in the traditional systems of irrigation and exploitation of water sources, especially the water sources behind dams, there isn't regular and consistent plan for their management and this can be caused the weakness of irrigation performance. in this connection, using both of optimization methods and geospatioal information system (gis) together can improve the performance of irrigation pro...

A simulation and optimization model was developed and applied to an irrigated area in Delta, Utah to optimize the economic benefit, simulate the water demand, and search the related crop area percentages with specified water supply and planted area constraints. The user interface model begins with the weather generation submodel, which produces daily weather data, which is based on long-term mo...

This paper presents a method to design efficient automatic controllers for an irrigation canal pool, that realize a compromise between the water resource management and the performance in terms of rejecting unmeasured perturbations. This mixed controller design is casted into the H∞ optimization framework, and experimentally tested on a real canal located in Portugal. The experimental results s...

Many optimization models exist for water management systems but there is a knowledge gap in linking bio-economic objectives with the optimum use of all water resources under conflicting demands. The efficient operation and management of a network of nodes comprising storages, canals, river reaches and irrigation districts under environmental flow constraints is very challenging. Minimization of...

Saline irrigation has been shown to be both experimentally and clinically efficacious in decreasing bacterial contamination as well as decreasing infection rates. The dynamics of irrigation delivery fall into two primary categories: simultaneous and intermittent irrigation. An important component to irrigation therapy is distribution of irrigation solution to hard-to-reach areas of a wound bed,...

this study was conducted to evaluate the current management of furrow and border irrigation systems in the dez irrigation network. of the eight farms studied, three grew wheat and one each grew corn, sugar beets, lettuce, sesame and mung beans. the study found water application efficiency in the five farms with furrow irrigation systems to be 25.8% and for the three farms with border irrigation...

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

Groundwater plays a vital role in the arid inland river basins, in which the groundwater management is critical to the sustainable development of area economy and ecology. Traditional sustainable management approaches are to analyze different scenarios subject to assumptions or to construct simulation–optimization models to obtain optimal strategy. However, groundwater system is time-varying du...
