PERFORMANCE ASSESSMENT OF A TYPICAL SEMI ARID WATER RESERVOIR FOR DIFFERENT KINDS OF OPERATIONS

The reservoir operations play an important role in conserving water. However reservoir operations go adhoc, many a times, for dealing with pressing socio-political needs of upstream or downstream users. There are many reservoirs in Indian geography where there are no consistent reservoir operation rules which are practiced. The existing way of operations practiced in the field, standard operating policies projected by water resources engineers, and new policies like hedging operations suggested by specialists need to be compared with appropriate performance criteria so that water conservation can be understood by field engineers. This has been simulated for a semiarid reservoir and several parameters of performance were applied suggesting where, when and how long one can hedge the water release for future use in an irrigation /water year. The flexible and feasible reservoir water releases using hedging can be employed
