River flooding, especially flash floods are a well known risk in Samoa where steep river catchments get frequent intense rainfall events especially in the wet season resulting in floods. On the other hand, there is few information about hydrological observation and flood control is not enough to prevent damages. Therefore, it is very important to predict the flood flow and the danger of the flood during such disaster. This paper will discuss the application of numerical simulation models to the rivers which flows through urban area of Apia. In this study, runoff model and flood calculation are combined to know characteristics of each flood Models have been used to simulate the flood propagation and thus verified against physical observations. The results have identified the inundated area and quantified flood hazard extent and intensity Future studies include fitting flood structures for flood mitigation measures.
