|Title:||Derivation of operation policies for the multi-purpose Ramganga reservoir|
|Published in:||Water and Energy International|
|Abstract:||Reservoir operation policies are derived for improving project performance. Their derivation lies in the resolution of six basic questions (James and Lee, 1971) using economic data. The first three questions pertaining, in sequence, to the operation for flood control, flood control and conservation, and conservation, respectively, are relevant to the multipurpose Ramganga reservoir (India) operation, for which policies are derived for known priorities of demands in hydrological context using simulation. For the flood control operation, the derived strategy is based on the cut-off storage and inflow and the inflow pattern, whether rising or receding. It is evaluated using available hourly flood records including design flood and is found to perform satisfactorily. The policy proposed for flood control and conservation operation in high flow season analyses for daily releases the future hypothetical storages derived from flow forecasts and assumed release patterns. Employment of this strategy to a critical year has been found to be beneficial by Rs. 411.91 million over historic performance. For the conservation operation, a multiple zoning-based policy utilising daily flows is derived. Its application to 16-year data yields net annual benefits of Rs. 71.31 million (over historic performance) in drinking water supply and irrigation and Rs. 20.46 million in power generation.|
