In developing countries, natural river regimes are increasingly undergone human modifications. All these constraints strongly affect the river systems. However, study on minor tributary of modified river is few. Thus the interest of this paper is to explore a tributary due to extensively regulated flow regime of mainstem river constrained by two barrages. The mainstem and tributary are deteriorating in its water quality due to the existing estuarial barrage impoundment. However by inserting anot...

This paper discusses the evolution of the foggara in time and the methods adopted by farmers to increase the water parts of owners. Field works were conducted in 2007, 2008, 2009 and 2010 in the oases of Timimoun and Adrar. Over 100 foggaras were visited. Surveys and interviews with the populations and the owners were conducted. Two ancestral methods are used by the farmers to increase the discharge of the foggara. This is an extension of part of the drainage gallery and the addition of one or m...

In 2004, the Jordan National Water Master Plan (NWMP) was developed, which includes a number of water demand projection modules for assessing the existing water resources, and predicting demands on water for all uses; municipal, industrial, tourist and irrigation. The Irrigation Demand Module was tested with historical data and comparisons were made between the predicted demands as obtained by the module, and the recorded water use provided by relevant institutions. Serious imbalances appeared, ...

Various methods and criteria have been proposed and utilized for the evaluation of irrigation systems performance, which can be used for comparison of design conditions and irrigation systems performance. Surface irrigation systems should be paid more attention among all other irrigation systems due to their operation simplicity and high losses. In the present study, while describing main relationships of irrigation evaluation criteria of application efficiency, water requirement efficiency, Dee...

Water management for irrigation in areas with high water scarcity includes not only domestic wastewater treatment but also practices for the reuse of drainage water during the irrigation period. The main problem that concerns the reuse of drainage water for irrigation is the accumulation of salts due to the effluents existing in the soil. In this paper an optimization technique is proposed for the management of drainage water that uses, in combination, a soil-water-plant model (SWAP) and a mixed...

A linear programming model was developed to assess the impact of different water prices on cultivated areas, irrigation water demand, net income and optimal cropping pattern in the Northern Jordan Valley (NJV). The results reveal that the price for irrigation water does not reflect any elasticity in the range of water prices between 0.01 and 0.06 JD/M3 indicating constant real economic water price of 0.06 JD/M3. The change in cultivated areas as well as water demand (reduction) starts at water p...

Field experiments were performed to study the effect that wind shelterbelts has on irrigation uniformity of hand move sprinkler irrigation system located in northwest Kenya. Catch can tests were performed to evaluate the distribution of applied water using coefficient of uniformity and distribution uniformity for plots with shelterbelt and without shelterbelt scenarios. Three medium pressure twin nozzle sprinkler head types were tested to determine their water distribution uniformity at varying ...

The cost constructing for irrigation is often given in $/ha. In deciding whether a project is worth undertaking, it is important to weigh the anticipated benefits against the expected costs. In this study, unit area construction costs based on the way of project water supply (gravity, pump) and scheme type (classic canal, flume, pipe) were calculated for the 211 irrigation projects operated and constructed by DSI (State Hydraulic Works) in Turkey. In a case study of the 27 irrigation schemes con...

This paper provides the methodology and results of a cross-scale diagnostic performance assessment program of the irrigation water management in the old lands of the Nile Delta of Egypt. The analysis was done at three levels; main canal level, branch canals level and on-farm level of the Meet Yazid command (82,740 ha) for the year 2008–2009 to highlight areas for improvement. At the main canal level the annual average percentage of irrigation water returning to drains and groundwater was 53% of ...
