IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ABSTRACT
The Upper Dong Nai River Basin was studied to quantify the potential impact of climate change on the water quality
(TSS, T-N, and T-P) using a multi-model ensemble approach. Climate change scenarios (RCP4.5 and RCP8.5) were
developed from an ensemble of GCMs (General Circulation Models) obtained from IPCC-AR5. The simple downscaling
method (delta change method) was used to downscaling the climate data from global scale to regional scale to generate
the climate change scenario for the study area. The Soil and Water Assessment Tool (SWAT) was used to investigate
the impact on water quality under climate change scenarios. The model was calibrated and validated using monthly TSS,
T-N, and T-P records. The calibration and validation results indicated that the SWAT model was able to simulate the
streamflow satisfactory, with Nash-Sutcliffe efficiency exceeding 0.50 for the Phuoc Hoa station, for both calibration and
validation periods. Their differences in simulating the water quality under future climate scenarios were also investigated.
This study was expected to provide a useful tool and reference for non-point source pollution quantification and to
support water resource management and planning in the Upper Dong Nai River Basin.
