This study is to evaluate the use of dual-polarization radar data for storm runoff modeling in Namgang dam (2,293 km2) watershedusing KIMSTORM (Grid-based KIneMatic wave STOrm Runoff Model). The Bisl dual-polarization radar data for 3 typhoons (Khanun,Bolaven, Sanba) and 1 heavy rain event in 2012 were obtained from Han River Flood Control Office. Even the radar data wereoverall less than the ground data in areal average, the spatio-temporal pattern between the two data was good showing the coefficientof determination (R2) and bias with 0.97 and 0.84 respectively. For the case of heavy rain, the radar data caught the rain passingthrough the ground stations. The KIMSTORM was set to 500×500 m resolution and a total of 21,372 cells (156 rows×137 columns)for the watershed. Using 28 ground rainfall data, the model was calibrated using discharge data at 5 stations with R2, Nash andSutcliffe Model Efficiency (ME) and Volume Conservation Index (VCI) with 0.85, 0.78 and 1.09 respectively. The calibration resultsby radar rainfall showed R2, ME and VCI were 0.85, 0.79, and 1.04 respectively. The VCI by radar data was enhanced by 5 %.
