ABSTRACT

A lot of research on the application of GIS has been conducted in the field of water quality management. The function of a geometric data acquisition for reservoir and river models, however, is not enough to satisfy multiuser’ convenience. CE-QUAL-W2 is a two-dimensional (2D) longitudinal/vertical hydrodynamic and water quality model for surface water bodies, modeling eutrophication processes such as temperature -nutrient -algae and sediment relationships. The purpose of this study is to analyzing which bathymetry information affects hydraulic results. There are consisted of three scenarios under consideration. The first scenario takes into account only tribatary type data such as Heoin and Okchen river. The second scenario, Heoin river constructs to tributary and Okchen river constructs by branch. Last scenario constructs Heoin and Okchen river by branch. The RMSE error results for the first, second and third scenarios are 0.61, 0.36 and 0.28 respectively.
