The aim of this study was to assess the impacts of the changes in upstream flow and sea level rise due to climate change on seawater intrusion in the Sai Gon and Dong Nai Rivers in Ho Chi Minh City. The HEC-RAS model was used for simulating the salinity intrusion. The results of model calibration and validation indicated that the HEC-RAS model could simulate reasonably the streamflow and salinity concentration with NSE values exceeding for both calibration and validation periods. | Assessing the impacts of the changes in the upstream flow and sea level rise due to climate change on seawater intrusion in Ho Chi Minh city using the Hec - Ras 1D model
