ABSTRACT: Surface and groundwater are related systems. They can be used
conjunctively to maximize the efficient use of available resources. Groundwater
may be used to supplement surface water to cope with the irrigation demands to
meet the deficits in low rainfall periods. The parameters involved in the
present study are groundwater availability, surface water availability, water
requirement of crops and crop area. The inclusion of such uncertain parameters
leads to accept the decision making process beyond the consideration of
economic benefits. In the present study, an irrigation
planning model is formulated by considering the conjunctive use of surface and
groundwater. The resources in the present model, i.e. the area, surface water and groundwater availability are
represented by fuzzy set. The linear membership function is used to fuzzify the
objective function and resources. The model is applied to a case study of
Jayakwadi project and solved for maximization of the degree of satisfaction (l)
which is 0.546.
