NUMERICAL MODELING OF TWO-DIMENSIONAL POLLUTNANT TRANSPORT IN NAKDONG RIVER
The transport and dispersion of pollutants in natural rivers is a principal issue in river management. To study the pollutant transport in natural rivers, the effects of meandering and confluence of tributary on mixing processes have to be analyzed. Two-dimensional depth-averaged schemes are used to represent variations in the velocity distribution and water quality in a channel. The objective of this study is to evaluate the impacts of operating water gate of Nakdong Estuary Barrage on the river environment. The Nakdong River being used as drinking water sources for Busan and Gyeongnam province has been contaminated due to inflow of inadequately treated wastewater from the tributaries into the fiver. The computational domain includes the cross sections from the Miryang river junction to the downstream barrage end of the Nakdong River. The length of the reach is 45 kin. Mulgeum intake station is located west side of applied domain. During the operating of the water gate, the velocity magnitude and concentration are analyzed around intake. The effect of the pollutant flow from the Daepo stream, tributary of the Nakdong river, which is located opposite intake, is also analyzed.
