As part of the agreement Vertical Electrical Sounding was conducted at 10 points at Arjo- Dedesa between June 10 and June 20 2006. This report presents the results the geophysical investigation (Vertical Electrical Sounding) conducted in the area. The interpreted resistivity layers are generally correlated with the neighboring borehole logs. The thickness of the overburden is estimated to be 12-17m at the spillway and about 3m at the dam site. At the saddle dam the overburden is assumed to be very thick (greater than 40m). Electrical imaging is recommended in addition to the planned retraction seismic survey. 21Table of Contents 1.

Introduction 1.1 General 1.1.1 Location and Accessibility The investigation site is located in the Oromia Regional state, about540km from A Ababa, geographically bounded by 36 38’50’ E — 36 41 34 E and 8 32 34 29’52”N (Figure 1.) It can be accessed after driving about 460 km along Addis Ababa -Gore asphalt and all weather road. Turning to the right at 460km from Addis Ababa, about 80km dry weather road leads to the site of investigation. 1.2 Objectives The main objectives of the geophysical survey are: - To determine the nature and depth of the bed rock - To estimate the nature and the thickness of the overburden - To determine the nature of geologic structures if any 2.

The Schlumberger array was applied for the investigation. In this configuration MN (potential electrodes) are kept fixed and current electrodes (AB) are moved outward symmetrically in steps. At some stage the voltage difference between MN will, in general, fall below the reading accuracy of the voltmeter in which case the distance between MN is increased (Figure 3). The maximum current electrode separation was limited to AB/2=220-330m due to topographic problems. «---- AB/2----------------------------- AB/2 A MN Figure 3 Schlumberger array configuration 3.2.2 Data processing and presentation The observed apparent resistivity for each VES was ni „ plotted against half separation (AB/2) on double logarithmic paper. Approximate current electrode auxiliary point method was initially applied on the raw parameters (resistivity and thickness). — interpretation ■ da.a (b « r " U‘ " "4 - -he 5These layer parameters were used as initial model for more computer assisted iterative interpretation to obtain the final layer parameters. Finally, the VES data are presented as geo-electric sections using these layer parameters (resistivity and thickness). The geoelectric section of the spillway, the dam site and the saddle dam are presented in Figure 4, Figure 5 & 6 and Figure 7 & 8, respectively. 3.2.3 Data quality. The data quality of Vertical Electrical Sounding generally depends on the topography, orientation of the line, ground contact of electrodes and instrumental error. The Ar]0-Dedesa dam site is generally characterized by rugged terrain and ground contact of electrodes was poor, which is assumed to affect the quality of the data. 4. Data interpretation The interpreted VES results are presented in the form of sections (Figure-4 to Figure 8) and also summarized as shown in Tables (Table 2-Table 7). Lithological descriptions of the resistivity layers are taken from borehole records in the vicinity of the VES points Spillway Subsurface information for the spillway area was obtained from two VES observations, VES-1 and VES-2, located in the north-western and south-eastern part of the spillway respectively (Figure-2) VES-1 which is located in the north-western part and relatively at lower elevation displayed four resistivity layers (see Figure 2 and appendix).

Four resistivity layers are delineated under VES-9. These layers exhibit very high resistivity values (1460-8700 Ohm-m). The borehole log AD5 describes that thick trachyte body underlies the vicinity. Fractures observed on the trachyte are filled with white minerals. The high resistivity obtained suggests that the degree of weathering and fracturing of the underlying trachyte is less in the vicinity or the fractures are filled by high resistivity minerals like silica. Figure-6 shows the four delineated resistivity layers and their possible lithological description. VES-10 is located at relatively lower elevation towards the Dedesa river (Figure-2). The four layers delineated under VES-10 are characterized by very low resistivity compared to VES-9. The top 1.4m layer having a resistivity of 15 Ohm-m comprises silty clay. The second 653 Ohm-m layer is 8.7m thick . This layer is associated with slightly weathered trachyte. The third layer which is characterized by low resistivity (58 Ohm-m) is very thick (45m). This layer is lithologically interpreted as highly weathered trachyte The rise of the resistivity to 195 Ohm-m of the bottom layer indicate the decrease in degree of weathering and fracturing of the trachyte with depth Saddle dam The four VES points of the saddle dam area are distributed in such a way that th two VES observations (VES-5 and VES-6) conducted along ESE-WNW o ' eastern part of the saddle dam.

Conclusion and recommendation The Vertical Electrical Sounding (VES) conducted in the area delineated different resistivity layers corresponding to different lithological units, which are generally in correlation with the neighboring borehole logs. From the two VES observations conducted at the spillway the overburden thickness is estimated to be 12m - 17m. The bedrock is assumed to comprise highly weathered and fractured trachy basalt. The over burden at the dam site is very thin (about 2m thick). The bedrock is also marked by very high resistivity that is in thousands of Ohm-meters indicating that the bedrock of the dam site area is slightly weathered and fractured or the fractures are filled with high resistivity minerals such as silica. The results obtained from VES-4 and VES-10 suggest that the resistivity of the bedrock at the dam site decreases towards the river (in the vicinity of the flood plain). The saddle dam is generally marked by low resistivity (16-44 Ohm-m), 40-80m thick formation This formation is considered as soft formation and the relatively hard formation which assumed as a bedrock at saddle dam area seems deeper (about 40m deep at the south eastern part and about 80m in the north western part) The interpreted VES results do not show the presence of structures such as faults and shear zones. Recommendations The authors recommend Electrical imaging survey in the area in aridity . l. 'juiuon to the planned seismic refraction survey to get reliable and detail subsurface information 204.
