초록/요약
In the present study, the Total Maximum Daily Load (TMDL) was introduced to the Young-San river basin for the multipurpose expansion of the aquatic-ecosystem recovery and the water resource utilization of the Young-San Lake. For the methodology, the Young-San river basin was divided into 12 sub-basins in which point sources and non-point sources were investigated. The representative stations from the Young-San river were selected to estimate the hydraulic coefficients (a, b, alpha, beta) of the respective stations using HEC-RAS Model with the profile data from 『Ministry of Construction and Transportation, 1998』 Water quality prediction was performed by the QUAL2E Model with the input data from the water-stage network data of the Young-San River Flood Control Office and the water quality network data of the Young-San River Basin Environment Office. Based on the results from the water quality prediction, TMDLs for the respective sub-basins were proposed so as to fit the target water quality which was estimated in the river channel by the reduction of load.
