Reservoir siltation has negative effects on water resource development projects. The impact of sedimentation on FERC's licensed hydropower developments is often quite significant. Therefore, at Federal Energy Regulatory Commiss ion (FERC), managing sediment in reservoirs has become an increasingly serious problem. In a recent report, the World Bank has confirmed the seriousness of the problems worldwide. The Bank estimated that on a global basis the average replacement cost of the annual reservoir storage capacity loss due to siltation alone is approximately $6 billion. However, careful project planning and management can greatly mitigate or completely avoid many such problems.
