Assessing influence of climate change on the flow of Vi Gia river basin, Quang Nam province by SWAT model.

Abstract

In recent years, climate change has greatly impacted on the Vu Gia river basin, Quang Nam province; therefore the application of model is a new approach to solve and forecast environmental problems. This study applies SWAT model to assess impacts of climate conditions on the flow of Vu Gia river. This provides information for the orientation of management and planning for the river basin to contribute to the sustainable development of the basin. In this research, input data of SWAT model is collected from 2001 to 2010. Model calibration and validation results are based on observed flow at Thanh My hydrological station with NSI of 0.78 and 0.91 respectively. It can be seen that SWAT model can be applied to assess Vu Gia river’s flow changes under the impact of climate change.
