the purpose of this study was to investigate and analyze factors influencing farmers’ participation in irrigation networks management, with an approach to compare two groups of farmers (one in irrigation networks with wua (water users' association), and the other in networks lacking wua). the methodological approach was a descriptive-correlational and causal-comparative study of the survey...

Drawing from the encouragement of Prof. Norman Uphoff to start SRI in Kenya, the first meeting to plan and introduce SRI was held at the Mwea Irrigation Scheme in July 2009, organized by Prof. Bancy Mati of JKUAT and Markus Moeller (then the Irrigation Specialist at the World Bank office in Kenya). The two drew together some like-minded individuals to form a collaborative team comprised of staf...

In past couple of decades, there is immediate growth in field of agricultural technology. Utilization of proper method of irrigation by drip is very reasonable and proficient. A various drip irrigation methods have been proposed, but they have been found to be very luxurious and dense to use. The farmer has to maintain watch on irrigation schedule in the conventional drip irrigation system, whi...

according to the low efficiency of irrigation and drainage networks and water distribution in iran, simulating water flow and sensitivity structures and networks is considered as a new approach to evaluate the performance hydroelectric projects in the country. in this study, because of reduced water supply and distribution, especially in downstream irrigation and drainage networks varamin to ev...

the main objective of this study was to develop an assessment model for the virtual water of irrigation networks using analytical hierarchy process. for this purpose, 14 modern irrigation networks of iran were selected. also, 14 effective factors on the virtual water of these systems were considered as decision criteria. expert choice software was used for ranking the virtual water values of th...

At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...

The designating factors in the design of branched irrigation networks are the cost of pipes and the cost of pumping. They both depend directly on the hydraulic head of the pump station. It is mandatory for this reason to calculate the optimal head of the pump station as well as the corresponded optimal pipe diameters, in order to derive the minimal total cost of the irrigation network. The math...
