Abstract:

Shiroro Dam, constructed across the Kaduna River in Nigeria, is a rockfill dam with reinforced concrete facing. The dam was completed in late 1983, and reservoir impounding started in May, 1984. Instrumentation was provided in the dam to monitor its behavior while under construction and during and after reservoir impounding, and data from this instrumentation indicate that the dam has performed satisfactorily. Some initial leakage was treated by placement of a silty sand blanket along the junction of the concrete face slab and the foundation toe slab, and leakage was successfully reduced to a nominal amount.
