Abstract :
To protect from the risks of drought and water crisis in the future is needed that guidelines and rules for utilization of limited water resources be taken. In this context, mathematical programming models are used to help solve problems related to water resources management widely. In the present study in order to proper exploitation of groundwater and surface water resources and the optimal allocation of these resources in agriculture sector and also to determination an optimal cropping pattern that conducive to achieve the maximum possible profit for farmers of Roudbar Alamout region, from Fuzzy Goal Fractional Programing (FGFP)model and statistical data related to year 2010-2011 were used. The proposed model was solved in GAMS software version 23/9. The results showed that utilization optimal cropping pattern and optimal allocation of existing water resources in case study region in addition to reducing water used in farms level, the product cost in per hectare of lands reduced, the utilized labor force increased and efficiency indicators "profit ratio to water used" increased about 13 percent. In the end, according to obtained results planning and modeling from bottom to up for development agricultural sector of Qazvin province was proposed.
