This paper describes criteria of caution and warning on evacuation of district in floodplain including small-medium sized rivers. We computed flood flow with inundation and from breach along rivers, in order to focus on depth and velocity in inundation area. As results, municipality alert to residents in almost districts for shelters, however if they lose the timing to evacuate, residents can choose to evacuate more than the second floor in house. Criteria of evacuation in few districts are discussed by accumulated precipitation, hourly precipitation and water surface level in rivers. We estimated the temporal difficulty of evacuation shelter in inundation from results of flood flowing analysis. Evacuation judgment criteria were suggested to be able to change evacuation more than second floor at occurrence of the difficulty to evacuate.
