| dc.description.abstract | Dendo Dam Project is one of the Bilate Irrigation Projects undertaken by Water Works Design and Supervision Enterprise (WWDSE). The dam site is located around 347km south of Addis Ababa and bounded by geographic coordinates of 395800-399000E and 780200- 782800N. The main purpose of this dam project is to provide irrigation to the agricultural land which is situated in the northern part of Lake Abaya, southern part of Ethiopia. The success of this proFigure 1ject will highly depend on the availability of suitable embankment material as it plays great role in the design of the embankment to be constructed. Earth and rock fill embankment dams are tolerable in most of dam site particularly in seismic prone area and since everything from clay to large stones are used in their construction, it requires low capital investment and can be completed in short period of time with minimum environmental impact. However, improper use of construction material and carelessness during investigation stage causes embankment failure by piping and seepage, foundation blowouts, overtopping and others. Therefore, identification of the material based on: engineering, mineralogical, and dynamic property and the site conditions have substantial impact on the long term stability and economic feasibility of a given Embankment project. Therefore, in the light of these important points the main objective of the present study was to Characterize and carry out Suitability Analysis of embankment material with special consideration to core and filter material. For this representative samples were collected from the borrow areas, and laboratory tests were conducted to know index and engineering properties of the soils. The laboratory test conducted on soil samples during present study are: wet sieve analysis, Hydrometer analysis, Atterberg limits, shrinkage limits (linear), proctor compaction, permeability and x-ray diffraction (XRD). Test conducted on sand sample is sieve analysis. Besides, secondary data generated during previous study has also been procured from the project office. Based on the test results generated during both studies (previous and present) characterization and suitability analysis of embankment material was done. Finally, based on the results and finding of the present study, recommendations have been made | en_US |
