The study reviewed the model application on the Ango agricultural water zone within Ansung river basin through field site survey. This research was implemented by element spatial data which were a topographic map of 1/5000 and river network map of 1/25000 and some datum collected in the field. And Data for Irrigation facilities was used by water management information project. And spatial analyst was implemented under GIS environment by river network map and created analyst river. And unique HydroID was named to spatial objects and established its phase relation from the vector river network. In the future, This research will be used for the relation supply estimation method connected AWDS using Automated agricultural hydraulic structure irrigation network program developed by this research.
