Hydrologic system for simulating reference flows in the Geum River Basin's TMDL practices
In South Korea TMDLs are now calculated in the administration boundaries (similar to counties in the U.S.) along the main rivers by multiplying a calculated reference flow times the water quality concentration of different parameters. To model this practice, a hydrologic system was implemented which simulates daily stream flows at the 36 main gauging stations along the streams within the Geum River basin. This computer system uses the DAWAST runoff model to calculate return flows from paddy fields, domestic and industrial uses, and was verified using two years of observed data measured every ...
