Abstract: The Climate change is judged to impact seriously to human society. Hence, assessing the variation of climatic factors in this process is indispensable to mitigate its negative impacts. Quang Nam Da Nang area covered 3 large river catchments (Vu Gia Thu Bon, Tam Ky, Cu De) is predicted to be affected violently by the change of climate, especially on water resources security, as well in hydrological disasters. With the aim of evaluating the consequences of climate change, the study utilizes a semi distributed hydrological model (SWAT model) to simulate the stream flow variation in Quang Nam Da Nang area. The model is constructed with specific catchment characteristics. It is calibrated and validated over a period of 38 years from 1979 to2016 with the impressive coefficients (NASH reachs to 0.87, R reachs to 0.94). The data about climate change is supplied by Vietnamese Ministry of Natural Ressources and Environments.
