N2  - A GIS-based decision support model was developed for On-farm Water Management (GlS-OWM). The model includes three modules for water requirements calculations; crops manipulation and On-farm Water Allocation. The model was verified in an area located between Dakahlia and Kafr Elsheikh governorates. Egypt during (1/10/2013 to 1/10/2014). The ETo values which were estimated using GIS-OWM were highly significantly correlated with the ETo values estimated using FAO CROPWAT. The consumed time to reach the selected gates on Bahr Elbeshma canal using the GIS-OWM model were also highly significantly correlated with the actual consumed time to reach the same gates. The forecasting gross irrigation requirements for the pattern distributed using GIS-OWM (m3) was compared to the canals available water (m3) WId the gross irrigation requirements for the actual pattern (m3). The saved watter amount during summer season when GIS-OWM is verified is (l.22 X 107) m3 for 11795 Feddans. This amount represents about 34.6% of total water available during this period. GIS-OWM is able to generate maps for On farm Water Allocation and field irrigation status
