ABSTRACT
Rock formations are generally perceived as favorable and good bearing stratum. However, there are many challenges in design of earthen reservoir foundation on a rocky profile. Geological mapping coupled with comprehensive geotechnical investigation is a vital requirement for such studies. The geological mapping needs to encompass the study of active folds, faults and any other geological concerns. The geotechnical data need to be detailed covering the permeability, compressive strength, water absorption etc. which are critical in the achieving the reservoir water tightness. This paper outlines the various challenges confronted in earthen reservoir design in a rocky landscape and the solutions provided for a project case.
