HYDRO-MODULE DETERMINATION FOR VANAEI VILLAGE IN ESLAM ABAD GHARB, IRAN

In order to design a network of irrigation channels, it is necessary to determine cropping pattern and HydroModule of area. Then according to the water requirement (Hydro-Module), flow through each irrigation channels is calculated. In addition, in many villages, due to the poor knowledge about water requirement to agricultural uses, irrigation efficiency is low or crops are exposed to water stress. Thus, Hydro-Module determination gives many advantages to experts and farmers. In this study, after being informed from cropping pattern of Vanaei Village located at Eslam Abad Gharb in Iran (query from local farmers and using NETWAT software), by using CROPWAT software, Hydro-Module determined for this village. Finally, results compared with AGWAT software. The amounts of calculated Hydro-Module using CROPWAT software and AGWAT software were 0.78 and 0.73 liter per second in each hectare, respectively. Among the cultivated crops in the villages, sugar beet has the greatest net irrigation requirement. Therefore, according to the water resources limitation, it should be considered further. Because there is sugar factory in the Eslam Abad Gharb city, there is no possibility of sugar beet production reduction or changing of cropping pattern. Therefore, it is essential to use the correct administrative procedures in this village for avoid from water loss and increasing of crop yield.
