Assessment of conjunctive use planning of water resources: A ease study of Sultanpur district-Uttar Pradesh, India

摘要

The amount of available water resources have been recognized as limiting factors in development of most of the semi arid regions. Optimal utilization of available surface and groundwater resources, in canal command areas would result in their better utilization by maximizing the net benefits from the crop production. But shortage of surface water supplies has increased the pressure of ground water utilization and development as well. The potential of groundwater can be used to develop conjunctive usewater management plans for supplementing canal water supplies and to increase agricultural productivity. The feasibility of conjunctive use management is analyzed using a mathematical mode in the Shard a sahayak command area of Sultanpur district of Uttar Pradesh-lndia. The water demand and available water resources in the study area in the study area in the study area are evaluated considering surface water and groundwater. This paper presents a simple economic- engineering optimization model to explore the possibilities of conjunctive use of surface and groundwater using linear programming, and to arrive at an optimal cropping pattern for optimal utilization of water for maximizing net benefits. The UNDO 6.1, optimization package has been used to arrive at optima allocation plan of surface water and groundwater. The results indicate that conjunctive use options are feasible and can be easily implemented in the study area.
