Performance assessment of storage policies of the Vaigai Reservoir using a simulation model

Abstract

A comprehensive simulation model was used to assess the performance of the storage-based operating policies of the Vaigai Reservoir system, Tamil Nadu, India. The model first used historical inflow data, and then inflow data generated through an artificial neural network (ANN) model. The modelled releases were then compared with the actual ones. It was found that the existing storage-based policies were violated within the year but not on an annual basis, except in the recent past, when annual deficits occurred due to inadequate water availability from the upstream reservoir.
