ABSTRACT

In this research the rehabilitation of irrigation system of Research and Aplication Farm of Adnan Menderes University Faculty of Agriculture was investigated involved with the climate-crop-soil properties of project area, and also it was aimed to determine the most appropriate irrigation system and water distribution method for the irrigation one. For this purpose; two different water distribution planning (continuous flow and rotation methods)  was made above two different irrigation schemes (open channel an high presure irrigation system) and totally four different irrigation project was developed.

The highest irrigation module of the year was used to determine the system capacity to be carried with the pipes or channels in water distribution schemes. Irrigation module datas that used in the projects is 2.08 l/s/ha for open channel system and 2.12 l/s/ha for pressurized system.

Open channel irrigation system was planned with three seconders and 21 manifolds connected to those. In pressurized irrigation system whole irrigation area is irrigated by 9 valves.

In the management of open channel irrigation system, system capacity is 292.88 l/s in continuous flow method and 925.39 l/s in rotation method; so system elements were planned according to these values. Five rotation groups were planned to irrigate the involved area in 24 hours equally.

The management of high pressure irrigation system is similar to open channel irrigation system, continuous flow and rotation methods were planned and capacity of pipe lines were determined. In continuous flow method, system capacity is 298.52 l/s and in rotation method it is 1506.68 l/s. In the method applied, three rotation groups were planned and each groups is irrigating the area in 24 hours equally.
