| Abstract | The operation of a storage based reservoir modifies the downstream flow
considerably in the low flow season. If there are a network of reservoirs in a basin then the
downstream flow augmentation due to the combined operation of the upper reservoirs can be
of considerable amount to be used for other purposes like irrigation, water supply or power
production. The case for this study are the two proposed storage based reservoirs located in the
upper tributaries and an existing irrigation project located at the outlet of Gandaki Basin,
Nepal. The reservoirs are proposed for power production but at the same time it will augment
the flow at the Irrigation Project that can be used for the irrigation as an additional benefit.
Based on the well known Stochastic Dynamic Programming (SDP) optimization
technique, a SDP Model is developed which is used for finding the optimal operation policy of
the reservoirs. Using the so generated operation policy and a synthetically generated long term
inflow series, the modified flow downstream of the reservoirs are simulated and mass balance
equation is used to calculate the additional flow, with its reliability, at the irrigation project due
to the operation of the two reservoirs. The additional amount of flow over the dry season (Jan
to May) is nearly one forth to double of the existing supply available at the irrigation Project
with a reliability of 80 % and it recommends strongly to the priority in the national plan for the
construction of these reservoirs. |
