Abstract: Flood is a common hazard among all natural disaster and it causes the most problems. It is impossible to avoid risks of floods and prevent their occurrence. However, it is possible to work on the reduction of their effects and reduce the losses which they may cause. In order to understand the magnitude of floods as well as the contingency of planning and management decision, river modeling and flood hazard mapping have become more in demand for decision makers to understand the situation. This study is aimed to develop map flood risk by superimposing 4 hazard maps such flood hazard maps and probability of landslide hazard map. Flood hazard maps will be separated in to 3 scenarios which flood hazard map from 100 years return period of peak rain fall, land use change and climate change. The results show that risk of flooding is high around central area and southern part of Laos. . Following it, the flood risk map was compared with records of historical flood events to confirm the valid results
