ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...

Due to water use increasing, attention to optimal water resources allocation is needed. In recent decades, the use of intelligent evolutionary methods for optimization of water allocation was focused more by researchers. The aim of this study is to development on water resources planning model that determined the proper cultivation, optimal exploitation of groundwater and surface water resource...

many real water resources optimization problems involve conflicting objectives. in this study, multiobjective genetic algorithm nsga-ii, has been developed for optimization the conjunctive use of surface water and groundwater resources and optimal management of supply and demand of agricultural water. here, optimal allocation of land and water resources to the dominant products in najaf abad pl...

The optimal allocation of water is importance because Yazd province has very limited access to water resources. The optimal allocation requires that the water price be approximately equal to its economic value. Accordingly, the present paper calculated the economic value of water consumed by manufacturing industries in Yazd province. The Cobb-Douglas, transcendental, translog, generalized quadr...

The unavoidable consequences of increased demand and decreasing water resources and Deduction rainfall and drought is caused to arise disutes among water user in recent years. On the other hand, vital need of agriculture sector to water and developing industry sector in Isfahan, have increased competition between water users of industry sector and agriculture sector. In this paper, we use...

The scarcity of water resources and supply resources limitation, have caused an increasing gap between water supply and demand specially in recent decades in almost all regions of the globe. One of the best known solutions proposed by the economists is using the different water pricing approaches thereby obtaining the optimal allocation and social justice. To this purpose, this paper uses the p...
