considering that agricultural sector is the largest consumer of water, presenting integrated management for water resources and formulating effective policies to increase water productivity in this sector is essential. therefore, using economic modeling , this study simulated the farmers’ responses to irrigation water pricing and rationing policies in zabol city. to achieve the study purpose, t...

By definition, integrated water resources management (IWRM) deals with planning, design and operation of complex systems in order to control the quantity, quality, temporal and spatial distribution of water with the main objective of meeting human and ecological needs and providing protection from water disasters. Complexity is a result of water resources system structure and interaction betwee...

abstract in current study, an irrigation examination and acquisition of environmental water in kor-river fields, that is dominated from doroudzan dam to bakhtegan lake, was done by an integrated economy-environmental model. the model was considered by economic, hydrologic and agronomic components. in the economic component, an optimal harvesting of water was done using non-linear programming in...

Abstract Water resources allocation is an important technical tool to alleviate the conflict between water supply and demand, improve utilization efficiency, achieve control target of total utilization. However, current theory immature, there are few objective quantitative methods, which leads relatively backward practice. Moreover, amounts allocable change dynamically, makes static single trad...

In the past, water resources in Australia have been over-allocated and this has led to the implementation of water reforms. An integrated assessment project is underway in the Namoi Catchment, located in New South Wales, Australia, that aims to assess the social, economic and ecological impacts of reductions in water allocations under current and future environmental conditions.
