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 research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...

irrigation management transfer to farmers is one of the important and necessary issues for irrigation planners globally. irrigation management transfer or participatory irrigation management by water users’ associations (wua) is a widespread strategy in the world and a good way to remove the country's irrigation and drainage systems problems. the main objective of this research was respons...

Koot - Hamoodi are two units from seventh units out of 1&2 irrigation and drainage network in Dasht-Azadeghan project where was past about 7 years from their operation. Results of the studies were showed before construction of network; ground water table in considered of this area was high and more than 90% of these lands were high and too high in saline and alkaline. After construction and ope...
