Abstract :
On-farm Water Allocation Module (OFWA) in GIS-OWM Model is considered as a decision support tool for water allocation. OFWA module helps to equity on water allocation among fields by generating dynamic maps. The GIS-OWM Model conducted during (1/10/2013 to 1/10/2014) in an area located in between Dakahlia and Kafr Elsheikh governorates, with net served area of 11795 Feddans. The water allocation dynamic maps can be generated based on gross irrigation water requirements calculations. In addition, the results indicated that, Irrigation field status dynamic maps among fields can be generated per hour during rotation ON-Times to illustrate the irrigation progress. The statistical analysis of the experimental location studies indicated that, there were a convergence between results of GIS-OWM consumed time to reach the selected gates and the actual measured time.
