This study was to develop the flood analysis module (FAM) for implementation of a web-based real-time agricultural flood management system. TheFAM was developed to apply for an individual watershed, including agricultural reservoir. This module calculates the flood inflow hydrograph to thereservoir using effective rainfall by NRCS-CN method and unit hydrograph calculated by Clark, SCS, and Nakayasu synthetic unit hydrograph methods,and then perform the reservoir routing by modified Puls method. It was programmed to consider the automatic reservoir operation method (AutoROM)based on flood control water level of reservoir. For a 15.7 km2 Gyeryong watershed including 472×104 m3 agricultural reservoir, rainfall loss, rainfallexcess, peak inflow, total inflow, maximum discharge, and maximum water level for each duration time were compared between the FAM and HEC-HMS(applied SCS and Clark unit hydrograph methods). The FAM results showed entirely consistent for all components with simulated results by HEC-HMS. It means that the applied methods to the FAM were implemented properly.
