Abstract

In the present paper Preemptive Goal Programming (PGP) model has been developed (MRPPGP) and applied to Mahanadi Reservoir Project (MRP) system, situated in the state of Madhya Pradesh, India. The objective of the present work is to find out a better operation model for MRP system at its ultimate development stage. For the justifiable comparison of performance of MRPPGP model with the earlier reported models (HEC-3, MRPSIM, and CDDP), the same data set has been utilized. The MRPPGP model shows better performance as compared with the other models and is identified as the most suitable model for MRP system. In the second section of the study the PGP model is applied to MRP with the modified demand and inflow data. The irrigation demands are computed as per the guidelines by FAO-24 considering the effective rainfall in the command area. Based on the concept of net-inflow the inflow series were reconstructed. Furthermore the study was extended to explore the possibility of increase in the designed net culturable command area (CCA). It was observed from the results that by the application of MRPPGP model utilizing the modified data, an additional 10% net CCA can be irrigated. It is concluded that the MRPPGP model can deal effectivelly with the priorized demands and in case of MRP system its application shows significant improvement in the operation policy as compared with that given by other reported models.
