The Naghlu reservoir has been studied to determine the level of siltation and sedimentation characteristics in the reservoir bed. The study was fulfilled in two phases, i.e., field survey and laboratory work for determining the level of siltation and carrying out the grain size analyses of the collected sediment samples at 34 locations representing the whole reservoir area.
The Naghlu Dam is a gravity dam which has been built to generate electricity. The dam was built on the Kabul River. Two main tributaries of the Kabul River, i.e., the Kabul and the Panjshir, feed the reservoir. The catchment area of Kabul and Panjshir tributaries feeding the Naghlu reservoir is around 26,000 km2. The reservoir’s surface area is around 15.5 square kilometers, and the volume is 550 million m3 at the normal operation level; the useful volume of the reservoir is around 380 million m3. Dam provides 100 MW of electricity for the surrounding areas, including Kabul and Jalalabad.
