This study problem of flood in 20 last year. Happen in Thailand. Though, Flood occurrence is important problem in area is Srisaket Municipality, Srisaket. The researcher conducted a study the flood mitigation by using HEC-RAS 5.0. Simulated flood conditions in the basin of a river area is Sisaket Municipality, By fix condition upstream boundary that the station, M.190 and Huay Samran estuary at Pho Subdistrict, Muang Srisaket, Srisaket. Testing compares with coefficient has Manning’s n channel was 0.035 - 0.065. In case study has chosen the date 1 August to 30 October, 2011. That year have topmost flood and get study the trend in inundation slackening keeps both. By the non-construction, compose the map flood risks in year of return period for takes to keep use warn. When compare with the rainfall. Create map warning of Flood by use water level and discharge relationship at Hauy SamRan between M.190 and M.9 for warn. And water level flow to Srisaket Municipality at discharge 300 - 800 cms. Have max water level  120.96 - 123.90 m.msl
