/.J location and Accessibility'
The proposed Upper Beles irrigation protect is located m the Amhara Region in rhe Belo river sub basin in the west central portion of the Abbay river basin, south west of Lake
I ana The main Beles River originates at the foot of the escarpment dividing it from Lake Tana and flows to die southwest.
The Upper Beles Balancing Storage Reservoir is located nrar Jawi, a small wereda town which is 157km from Kosobcr located on the junction of the main asphalt road. Jawi is located about 600km Nortn-XXcst of Addis Ababa Jawi can be reached after having (ravelled foi 443km from Addis Ababa along the main Addis Ababa-Bahir Dar asphalt road to Kosober and then driving for 157km off the mam asphalt road through < hagm, Gilgcl Beles and Pawn. Jawi can also be accessed from Dangla through Wcrk Mcda on 80km dry weather road which is under construction Generalised loc ation of I pper Beles irrigation protect area is shown in figure 1Wile ImRJtion .ind Draliugr Schemes F-actujI CeotrehniejdInvmigjilon Kepcn [Lot 2i Unr<f Bek* jlttica^ Storag Rrhnuir]

brief description of regional and site geology
2.1           RcgfoaiJ Geology
The geological units in Ethiopia fill into one of rhe following three maior catepones; the
Precambrijtn Bascmeoc. T ale Palcoioic to EaHy Ter nan sediments and the Cenozoic
vulcanic and associaicd sedimentary rocks.
The Upper Ikies irrigation project area comprises the above units, ilese are explained as
follows. starting from thr basement complex
PRECAMBRIAN BASEMENT
F’.Tprwuiesi arp found m area's not inteiisivc'ly affected by Cenozoic volcanism and idling and
where the Phanero/oK cover rucks have been ernded away. Precambrian rocks util crop in
four major regions around the plateau margins. ITiese areas are Ln Tigray region in the
north; along the Sudan border in Goiam, Wollega, JIluLabor and Ke I a regions in the wc^i. m Sidanui and Hale regions m the south and in Haierghe region in the east.
•      Large tract of Land underlain by the relatively low grade volcano-sedimentary
succession known as:
S PR2rd (Tulu Dimtu Group): Mrtjibasak, Metaandesite. grrm shist, phylite. mctaconglonwratr. quartzite and amphibednrs.
•       TntTUMVC rocks occur enclosed by gnelsslc Terrains of Early Proterozoic to
Archaean age:
ARI (Aligc Group): Biotite and hornblende gneisses, granulite and nugmaiitr with minor mria^editnentaxy  gneiss, Consisting  of dominantly grey  biotite-hornblende gneiss and granulite of vadiblc color, in pan containing  ill defined masses of relatively  uniform orthogneiss of granodiontic, tonalitic and diuntic compositions
•      Early or pre-iectonic plutonic bodies
fib,  th,  gd/  m,  ,  and  gt2  arc  internally  foliated  and  concordant  with  their
host rocks

SEDIMENTARY COMPLEX
Two major transgr^sion-regtession cycles took place during the Mesozoic era Kaznun
1972).
Addis Geosystems CohdNile Irrigation and Drainage Schemes Factual Geotechnical Investigation Report (Lot Z: Upper Ik-kw lUbnongStnrage Hvscrvuir)
Adigrat Formation (Ja): l*hc first transgression started in the Fatly Jurassic or I-ate Tnassic from the Ogadcn region in the Southeast towards northwest and reached its maximum extent in Kimmcridgian A digrat Formation Qa) were deposited dunng this time consisting mainly of sandstone and minor lenses ol siltstone.
TERTIARY VOLCANIC AND SEDIMENTARY ROCKS
Mohr (1962) divided the Cenozoic volcanic rocks of Ethiopia into the Trap Senes and Aden Scries. ’Die term Trap Series is still widely used to refer to the whole pile of the Tertian’ flood basalt sequence with intercalation of felsic lava and pyroclastic rocks (commonly on the upper part) which form the northwestern and southeastern plateaus and attain a thickness of up to 3 km The name Aden Senes was used for post rift 'Middle Miocene to Quaternary) volcanic rocks of the Main Ethiopian Rift, Afar Depression and some pans of the Ethiopian plateaus.
Ashangai Formation (Pza): The Ashangi Formation represents the carbest fissural flood basalt volcanism on the northwestern plateau. The basalt Hows arc several hundreds of meters to a kilometer (hick of strongly weathered, crushed, tilted basalts which lie Ik low the major Pre-Oligocene unconformity (Zane run et al, 1980). The Ashangi Formation consists of predominantly mildly alkaline basalts with interbedded pyroclastics and rare rhyolites and is commonly mice ted bv dole rite sills and dykes
Tarmabcr Gusaa (PNtb): Tarmaber Formation represents Oligocenc to Miocene basaltic shield volcanism on the northwestern and southeastern plateaus The central type Tarmabcr Formation basaltic volcanism was followed bv fissural eruptions particularly along the escarpments of northwestern and southeastern plateaus. Basalts of die Tarmaber Formation in contrast to the tholeiidc and mildly alkaline nature of the earlier flood basalts tvpicalh have an alkaline affinity.
QUATERNARY VOLCANIC AND SEDIMENTARYROCKS
Quaternary Plateau Basalts (Qbl): Quaternary alkaline basalts and trachytes were
erupted along preexisting structures on the northwestern and southeastern plateau Although, not dated, their relatively unmodified gcomorphological features such as the prevalence of prominent cinder cones and small collapse craters in particularly in a region of heavy rainfall and perennial streams indicire their recent age Alkaline basalts and trachvtic lavas prevail m the Tana Graben and voung trachyte flows on dir Batu Mountain and Sanetc Basalts in Bale region (Kazmin, 1979; Meria rt al. 1973) all belong to this unit Field evidence suggests a Pleistocene age to all these rocks. \ okamc cones and flows of
scotaceous basalts arc well preserved in the Lake Tana Graben

1.1           Background
The Upper Belos Weir Project is part of a larger planned irrigation development under the Ethiopian Nile Irrigation and Drainage Project The main structures proposed consist of a weir on the Upper Beles River, a sand trap roughly 40m wide and 400m long and main irrigation canal.
This report describes the geophysical Two Dimensional (2D) Resistivity Imaging survey conducted at che location of the sand crap on the right side of the river close to the weir axis on November 27 and 28, 2009 for the purpose of geotechnical investigation
L2 Objective of the geophysical surveys
The original plan was to measure two lines, one along the weir axis (200m) and
another along the sand trap diversion structure on the right bank (100m) However,
due to weir site construction works already underway by Amhara Design and Supervision Works Enterprise (ADSWE). the plan was revised, and three lines were investigated only on the sand trap.
The main purpose of the geophysical survey conducted at the site was:
•     To determine the depth to bedrock
•     To determine the thickness and degree of weathering of the bedrock and;
•     To determine the existence of geological structures, i.e, faults and/or fracture
zones
The depth to bedrock at the site of the sand trap determines the cost of the structure, which depends on the difficulty of excavation co the extent of Misting if shallow bedrock may be found.
li 3 Location and Accessibility
The Upper Beles Weir site is found on the Upper Beles River, about 16 km
the ullage of Fendika in Jawi Woreda. Aw. Zone of the Amhara Regional State.
The site an be reached from the Addis Ababa-Bahir Dar h.ghway by branching the west at the town of Koso Ber Koso Ber is found at about 430 km from Add.
Ababa Thereafter, a good gravel surfaced road of about 100 km to the west * Chagni leads to Gilgel Beles. A northwards turn 3km west of G.lgel Beles on a 6km
long road leads to Fendika. From Fendika, access to the site is possible using a new track bulldozed by the ADSWE The location map of the project area is given n
Figure l-l.2. Geophysical Survey
2.1           General
Geophysical surveys provide useful information in the planning and implementation phases of large construction projects, where the geological conditions of the foundation beneath rhe proposed structure should be investigated. In this regard, geophysical surveys provide indirect information about the subsurface condition to supplement the engineering geological investigations.
The geophysical method employed in the present study is the Two Dimensional (2D) Resistivity Imaging Survey, which is able to furnish subsurface information both in lateral and vertical direction. Different geologic materials show significantly different physical properties, the measured property in this case being the resistivity of the subsurface to electric current flow.
2.2 Survey Loy out and Summary Statistic*
Three profiles. Line I co 3. were laid out in the area of the sand trap diversion structure as shown in Figure 2-1. Line I follows nearly the center line of the sand crap, and is 300m long, whereas Line 2 and Line 3 run almost perpendicular to Line I. The length of the cross profiles is in the range of 120 and 130m.
A  hand  held  eTrex  Garmin  GPS  receiver  was  used  co  measure  the  UTM  coordinates of  the  start  and  end  points  of  the  geophysical  profiles,  which  are  given  in  Table  2-1. It  should  be  noted  chat  the  Adindan  datum  was  used  in  rhe  acquisition  of  the  UTM coordinates.

2.3   Instrumentation and Field Procedure
The PASI I6GL Earth Resistivity Meter was used in the 2D resistivity imaging measurements, which is powered by the PASI model PI00-3 Energizer that can deliver current up to 500mA, at a maximum output voltage of 350 Volt Additions1 pieces of equipment used include:
•    Cable sets (for current and potential circuit)
•    Stainless steel electrodes
•    Connectors and dips, and
•    Hammers

4The Wenner electrode configuration was used, with smallest inter-electrode spacing (a) of 10m Multiples of the smallest inter-electrode spacing (na) ranging from n=l to n =4 were progressively used so as to increase the depth of investigation, the largest inter-electrode spacing mainly used being 40m However, for Line-1 measurements were made up to n=5, the largest inter-electrode spacing being SOm. The data is collected in such a way that the electrodes are arranged along a line with a constant spacing between adjacent electrodes. First, the profile is traversed with the smallest inter-electrode spacing, and then the process is repeated with the next higher spacing until the maximum spacing is reached.
2.4 Data Processing and Presentation
The 2D resistivity imaging survey data is first edited to remove any erroneous data which could have detrimental effect on the inversion process. The edited data is input co the 2D resistivity inversion software. RES2DINV, which automatically determines a two-dimensional (2D) true resistivity model of the subsurface for the data obtained from the imaging survey along a particular profile.
The program divides the subsurface into a number of rectangular blocks, and tries to determine the resistivities of the rectangular blocks that will produce an apparent resistivity pseudosection that agrees with the actual measurements. The inversion method basically tries to reduce the difference between the calculated and measured apparent resistivity values by adjusting the resistivity of the model blocks in a number of iterations. A measure of this difference is given by the root-mean-squared (RMS) error,
The final output of the inversion provides three sets of sections, i.e. the measured apparent resistivity values, the calculated apparent resistivity response of the model ind the true resistivity model itself. The true resistivity model section is further ,ntcrpreted in terms of the local geology, and is presented in Figure 3-1 to Figure 3-3 for *e three profiles, respectively The inferred contact between the highly
ea thered rock/soil and the underlying bedrock is presented in Annex-1.
53. Results and Interpretation
3.1 Une-I
The    interpreted    2D    resistivity    section    along    Line-1    (Figure    3-1)    shows    distinct resistivity responses generally marked by low and high resistivity.
The low resistivity response, attributed to highly weathered and/or fractured rock, is observed at three locations along the line. The 50 Ohm-m resistivity contour is considered as the boundary between the highly weathered/fractured rock or soil and the underlying relatively massive bedrock The low resistivity zone stretches from about picket 30 in the SW to nearly picket 200 in the NE, attaining a maximum thickness of about 15m below pickets 60-100 and picket 150-190.
In the area between picket 220-240, the low resistivity zone (10-50 Ohm-m) appears to represent a sub vertical structure having a large depth extent, which proDably represents a weak zone. Also the area between picket 260-280 is underlain by such low resistivity response, which is still open northeastwards.
L lr»e
resistivity «dt> tepoyreyhy
Figure 3-1. 2D Resistivity Section along Une-I.
The  bottom  part  is  characterized  by  high  resistivity  response  varying  from  50  Ohm- m co greater than 300 Ohm-m. This high resistivity zone is probably the response ofslight!/ wea*ered to
Wh*Ch for™ ** bedrock in ^ea. The
portion lying between pickets 70 and 140. in particular is characterized by very high rssistMty. and thus may correspond to fresh horizons. The area between picket 0- 20 and 210-240 may be sites where shallow bedrock could be found.
3.2 tine-2
The 2D resistivity section along Line-2 (Figure 3-2) shows two zones of contrasting resistivity responses. Generally, the northern part of the line between station 0 and 90 is characterized by low resistivity values below 50 Ohm-m. and may be attributed to highly weathered/fractured rock. This zone extends down to more than 25m
below the surface, and further extends northwards beyond picket 10.
,n ^them part of the line between Picket 90 and 110. a high resistivity (>50 hm-m) material is found close to the surface and having depth extension. The high
^Jistivity body generally appears to have a northward dip. and is still open in the x °uth probably extending to the river bed indicating that the area is underlain by
X weathered to massive rock.

section along Line-3 (Figure 3-3) shows a simple subsurface
( ^t,f'Cat,On Except a small part in the southern tip of the profile at picket 100 and w ^°*c section is underlain by a low resistivity material of less than SO O
7m with resistivity progressively increasing with depth. This low resistivity layer i$
probably  composed  of  highly  weathered  and  fractured  rock,  having  thickness  of  10
co  15m.  which  is  expected  to  increase  even  more  further  north  of  picket  20  as  can be seen from the section.
Figure 3-3. 2D Resistivity Section along Line-3.
The high resistivity values at depth probably indicate the response of slightly weathered to massive bedrock. The depth to bedrock progressively decreases to the south, and is expected to be close to the surface north of picket 100.Conclusions and Recommendations
4 The  results  of  the  geophysical  surveys  conducted  at  the  proposed  Sand  Trap version  structure  clearly  indicate  the  nature  and  condition  of  the  subsurface materials.
Three profiles were measured at the site. On the first line, extending in the SW-NE direction, the surficial layer attributed co highly weatheredffractured rock or soil is fourKj between pickets 30 and 200 with thickness generally ranging from 8 to 15m
Between pickets 220 and 240, a vertical low resistivity anomaly (10-50 Ohm-m) with its resisovicy value decreasing with depch has been detected This anomaly may be interpreted as a nearly vertical scructure/weak zone, which extends to more than 25m depth. Ac the NE end of the line lying between picket 250-300. another low resisovicy is mapped which is open depth wise.
Line-2 and Line-3 run in the north-south direction across Line-1. The results along these lines indicate that depth to bedrock is deeper towards the north. On Line-2, overburden thickness of more than 20m may be found between pickets 0 and 55. whereas between pickets 55-80 depth to bedrock is in the range of 10-20m. In the area souch of picket 80, the bedrock is very close to the surface.
On Line-3, the bedrock outcrops in the southern part close to the river bank south °^picket 100 To the north of picket 100. che bedrock is covered by a low resistivity ^rial whose thickness varies between 10 and 15m. Generally, a northward
fCasc ,n thickness of overburden is observed
At intersection of Une-I with the other lines, very good match is found on the lr “  Preted depth to bedrock For example, at Picket 80 of Une-I and Picket 75 of
er
b depth to bedrock of Mm has been found. Similarly, almost outcropp g ij mapped at the intersection of Line-1 and Line-2.

discussed in an oblique manner during pre award clarification meetings/ correspond
which it was noted that ... "topographical surveys should he earned out at a higher density so // intervals of 0.5m are avaltable for the feasibility level designs*'
In fairly flat, un broken land the density of surv ey required for reasonable assurance of contouring accuracy' is considerable less than for steeply sloping and / or broken land
In addition to the deliverables required by the ToR. I laicrow have supplied the Digital Elevation Model (DEM) as well as high resolution Orthorectified Imagery of the Stuck Area
This provides the added benefits to the Ghent of using the high resolution DEM for design is opposed to contour plans, as well as highly detailed imagery’ as a backdrop to the contour plan.
1.2.2            Extent of Survey
The required survey / study area for Upper Bcles was about 138,000 ha compared toagron
area quoted in the contract ToR of 63,200 ha* 4. IVis more than doubling in survey / study area resulted in field survey’s and studies taking 3-4 months longer than anticipated ar the lnceponn stage of the feasibility study. ’I*he mam reason for expanding the Study or search area tor survr. was the highly fragmented and broken character of the area which subsequently nude identification of the desired +60.000 ha of viable net irrigable land for development in I pper Belcs quite difficult.

Given thai the satellites arc orbiting hundreds of kilometres above the earth’s surface, the reported accuracies arc impressive, Factors contributing to this performance are (i) the high accuracy to which the sensor position and orientation are known, which is then further enhanced by ground control; and (ii) the use of oblique images to enhance the stereoscopic
effect.

In order to understand the process and constraints of using stereoscopic satellite imagery in order was placed with Digital Globe tn December 20OT for imagery covermg about 2flOW (20.000 ha) of rhe Bries study area to be captured as won as possible us mg the new Worldview-
2 satellite, the best currently available.
The imagery tor this pilot (test) area was captured on 19,h January 2010 and was received on 26rh January 2010. A crimpatuon of contours generated using this stereoscopic imagery with spot heights from terrestrial survey was earned out, and shown below for two different areas In both cases the spot heights were within aboui 0.300m of the conrours, see Figure 2-1 and Figure 2-2 The pilot study confirmed the accuracy of the approach and in order placed for imagery for the full study area.

Because of the difference in troposphenc conditions encountered at Munzcn and BOO 3 due to rhe large height difference to rhe horizontal distance ratio, a different processing strategy had to be adopted for this baseline This difference in height causes the GPS signal m pass through additional Layers of the troposphere io reach 0003. Although the uopospbcnc modd used was the same for all baselines, an Lt + L2 frequency solunun was preferred for the Munzm to B003 baseline.

Dur to the survey only being based on one EMA station at Munzen. an independent check ww necessary to confirm the accuracy of rhe EMA station within the EMA network As there were
no additional HMA stations tn the vicinity a check was done by observing one 32 hour
observation session for baselines to the International IGS ncrwnrk Thia does provide an absolute check on the EMA station used (Munzcn) in the ITRE reference frame, but docs not provide a check on the relativ e accuracy of rhe EMA stanon with respect to any of the local
EMA stations in the vicinity. A full discussion of the mrrhods used and results is found tn
Section 23.3 The IGS station check iho proved that a GeoidaJ Model would improve ibe
accuracy of heights with respect to lhe geopotential surface
During processing GPS Antenna constants were checked against die Latcsi PCV calibration value* s. Reference coordinate triplets were checked agamst the final Control coordinate triplets
Sonic baselines were renbserved to provide additional robustness and a check on instnimenr setups from a previous phase. Redundant observation* were included in the processing.
Al! GPS Static and RTK Base Station setup information was recorded on GPS Static Eield Ixigs I.SM1F GPS !) and compared with the onboard recorded information during processing.
In&tnunent heights were measured and recorded both with a height hook and to the antenna phase centre which provided an independent check on inn tumen t heights.

3.2              Terrestrial Surveys
The validation of die detail ground survey was done primarily by cheeking the Tc
Control Stations on which GPS-RTK base stations were set up. During proecssi^^/
antenna constants were checked against the blest PCV calibration values. AU avetag J
were investigated for duplicated names and corrected.
During GCP surveys quality control checks were completed ever}- evening to ascertain th sufficient points where collected that conform to die quality critcna. GPS RTK points
processed and die locations compared with the GCP proformas to spot errors due to misidentification and inadvertent exchanging of points numbers between GPS numbering i- J numbering on proforma* Photographs were taken of even’ point to aid in the idenuficat^n of points on satellite images and assist with the exact location of the position where coordmrci
were taken.
3.3 Stereoscopic Imagery Processing and Accuracies
Within each GCP area a minimum of 4 points was selected with an optimum of 10which
creates redundancy and checks on the local accuracy of the srlected control within an area. Agreement of point residuals during the triangulation process within a GCP area indicates point selections, image accuracy as well as die accuracy of the GPS-RTK coordinates are correct.
The stereo-imaging software process for DEM creation has two basic report formats tlut provide an indication of the quality of the survey: (i) dir Triangulation Report; and (it) ♦he DTM Extraction Repon.
(a) Triangulation Repon
Tlie first is the triangulation report which provides statistics on the aenal tnanguuticin bundle adjustment This gives an indication of the accuracy of the intenor and exterior orientation parameters with respect to ground control. Table 3-1 provides a summan o results for rhe triangulation report.

The above table shows that the internal and externa) orientation parameters ai well as GCP’s are correct and conform to the required accuracy. All tie point residuals were found to be within the survey accuracy tolerances required
(b) DIM Extraction Report
As p>rt of DTM mass point creation a quality report is generated which provides statistics based on the height differences between the stereo-processed DTM compared to ground surveyed GCP‘s and topographic survey data This allows for an assessment of the true accuracy of ihc DTM model compared to actual ground surveyed data,
Table 3 2 contains a summan’ of the statistics generated from differences between the ground survey and DTM. Figure 3-1 shows a histogram of the errors based on the differences between the DIM and the Ground Trurhmg imrvcy.

Although nor required by the ToR a Digital Elevation Model (DEM) has been included as an added value deliverable. The DEM was created from die stcreoprecessed mass points and FIN with GCP*s to a height accuracy commcnsurale with that required The DEM Was created at
3.5m cell size with elevations at 32bit floating point sample depth AutoCAD dwg drawings were prepared for selected sites for ma for structures. I’he DEM fadljncs design work allowing planning of engineering infrastructure alignments, such as alignment of canals, drains, flood bunds and roads. and ground level profiles to be plotted and chosen alignments with the use of appropriate software such 6/MVfqfyw.
4,2 Contour Map*
Contour maps were generated from the above DEM. typically at 1.0m intervals. Where rrquircd. for example for sires surveyed by ground survey techniques, contours were generated at 0.50m intervals from lhe ground survey TIN models
43 OtThr/r^cnSed Imagery
Hit* above mntours maps were overlaid onto the orthorectified imagery . Orthorcctilicd images were produced from thr 0.5rn resoluaon unrectified panchroma oc images lhe orthorcctifwd imagery is available as an added value product even though this is not required by thr ToR.
Map? mar be printed ai any appropriate scale and a selection of contour / orthorectified imagery maps bjc included in the Al Albums of drawings including
•      50.000 scale maps (dwg nrs ITB/FS/TOP/50/06 09
•      20,000 scale maps (dwgs no: UB/FS/TOP/20/01-20
•      2,500 scale maps (dwgs nrs: UB/FS/TOP/2-5/11
Due to lhe very large survey area the numbers of maps required arc: (T) 4 at 50,000 scale; (ii) 20 ar 20 000 scale, and (iuj about 800 at .2,500 scale
+
A sample of the produced contour mapping (0.5 m contours) over ortho-rectified imagery at
l:2A00 scale is given in tbe A I Map Album, Map Nr UB/FS/TOP/X5/11, and shown at
reduced scale on Figure 4-1 and (to a higher scale) on Figure 4-2. Contours arc dsci shown at i
range of other scales on uibcr drawings included in the Al Map Album.
A single compete set of cotuow maps at 1:2,500 scale was. printed! off for reference. However it is. expected that detailed design will be dune using the DEM which allows information and data for (long / crass section) design to be easily extracted.fdctifl Dfnroauii.- RrfutbA: of Erbfofta.

Upper Beles Irrigation Project Summary

Upper Beles Irrigation and Drainage Project Feasibility Study

Project Overview

The document presents the feasibility study for the Upper Beles Irrigation and Drainage Scheme in Ethiopia, a World Bank-financed project covering about 80,000 hectares of net irrigation area. The study was conducted by Halcrow Group Limited in association with Generation Integrated Rural Development (GIRD) Consultants and completed in May 2011.

Key Components: Engineering surveys, geological investigations, topographic surveys, irrigation planning, and environmental assessments.

Geological Findings

Regional Geology

The project area features:

Precambrian basement rocks including metabasalt and gneisses
Mesozoic sedimentary formations (Adigrat sandstone)
Tertiary volcanic rocks (flood basalts up to 3km thick)
Quaternary alluvial deposits

Site Geology

At the Balancing Storage Reservoir site:

Unconsolidated alluvial deposits (clayey silt)
Residual deposits (gravel, silt, clay up to 12m thick)
Bedrock of welded tuff and amygdaloidal basalt

Geotechnical Investigations

The study included extensive field and laboratory testing:

Investigation Type	Details
Boreholes	2 boreholes drilled to 13-15m depth
Soil Sampling	10 disturbed and 6 undisturbed samples collected
Laboratory Tests	Grain size analysis, Atterberg limits, moisture content, consolidation tests
2D Resistivity Surveys	3 profiles to map bedrock depth and weathering
Trial Pits	Multiple pits up to 4.6m depth with hand vane testing

Key Soil Properties

Parameter	Range
Liquid Limit	35-65%
Plastic Limit	24-40%
Natural Moisture Content	27-59%
Undrained Shear Strength	40-140 kPa
Compression Index	0.25-0.39

Key Findings and Recommendations

Overburden thickness varies from 0-15m, with deeper deposits in northern areas
Vertisols (clay soils) dominate the command area with high plasticity
Potential weak zones identified in resistivity surveys
No groundwater encountered in boreholes at reservoir site
Bedrock quality varies from highly weathered to massive basalt

Engineering Implications: Foundation design must account for expansive clay soils, variable bedrock depth, and potential weak zones in bedrock.
