ABSTRACT

Identification of potential landslides and evaluation of landside risk during impounding and operation are deemed necessary to ensure the safety of the project operations. The scope of the current studies for the accomplishment of the aforementioned purposes is to review of published materials, interpretation of satellite images and topographic maps, site reconnaissance and preparation of geological map and preliminary assessment of hazard and risk of identified landslides. The interpretations presented herein are based on study of satellite (Quick Bird Google TM Earth) images, Survey of Pakistan (SOP) sheets, previously published geological maps and reports pertaining to the project area followed by ground verification in the field. This paper presents a preliminary assessment of the reservoir slopes, briefly discussing physiography, geology, potential and active reservoir landslides and a preliminary landslides risk assessment. The conclusions and recommendations provided at the end of this report summarises the studies conducted, potential and active landslides, their subsequent risk assessment and further need of detailed studies.
