TR-37 : Systems approach to optimize conjunctive use of surface and groundwater

Abstract

In the present study a conjunctive use model for optimum agricultural production in the sub-basin of the Ghataprabha command area in Karnataka State has been formulated. The aim is to develop an optimal crop plan, which is economically feasible and socially acceptable exploiting the irrigation potential both from surface and groundwater.

Ten crops have been identified for production on the basis of soil and climate and the cropping pattern observed in the area. The consumptive use and the net irrigation requirement of each crop have been computed. The groundwater resources and surface water availability over a time period have been estimated. A linear programming model has been used to allocate the optimal areas to different crops subject to the constraint of surface and groundwater availability.
