background: nowadays the eutrophication of water bodies is enhanced due to discharge of effluents and runoffs. therefore, there is a demand for the management of natural and artificial lakes to prevent or postpone this problem. lakes eutrophication is a complex process. therefore computerized models are very important tools to describe this process. although there are several models for this, b...

The South-to-North Water Diversion Eastern Route Project (SNWDERP) of China is a large inter-basin water transfer project. It is an extremely complex process management of water resources allocation and scheduling for such a multi-basin, multisource, multi-objective complex engineering systems. The SNWDERP is difficult to accurately construct the mathematical model because this kind of complex ...

This paper develops the system of optimal allocation of water resources in irrigation district and irrigation decision support which integrates technologies of decision support, information management, information search and so on. It has the multi-function of water production function calculation, crop water requirement calculation, water resources optimal allocation and realtime amending the ...

To plan a water resources system, fuzzy theory is introduced to handle uncertain future information. Representing runoff hydrograph and future water demand with fuzzy membership functions, the optimal site and scale of the system are decided through fuzzy linear programming. Then the construction schedule is calculated through fuzzy dynamic programming, under the conditions of limited finance a...

Streamflows in a Mediterranean mountain basin in the central Spanish Pyrenees were projected under various climate and land use change scenarios. Streamflow series projected for 2021-2050 were used to simulate the management of the Yesa reservoir, which is critical to the downstream supply of irrigation and domestic water. Streamflows were simulated using the Regional Hydro-Ecologic Simulation ...

Proposed dam construction in the Lower Mekong Basin will considerably reduce fish catch and place heightened demands on the resources necessary to replace lost protein and calories. Additional land and water required to replace lost fish protein with livestock products are modelled using land and water footprint methods. Two main scenarios cover projections of these increased demands and enable...

The operations of water resources infrastructures, like dams and diversions, often involve multiple conflicting interests and stakeholders. Agent-based approaches have recently attracted an increasing attention to design optimal operating policies for these systems. In this paper we contribute a general monotonic concession negotiation protocol that allows the stakeholders-agents of a regulated...

sahand dam with 135 mm3 storage located in southwest of hashtroud city is one of the important dams of east azarbijan. water storage of this dam supply drinking, industrial water demand of hashtroud city. furthermore, it used for irrigation of 11 hectares of the sector land. according to importance of this water resource, quality of dam reservoir water and related surface water and ground water...

Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...
