In Korea, around 25 oil and chemical water pollution accidents take place every year. In case of middle or large chemical spill in river, not only field response but also forecasting for the arrival time and diffusion concentration is important. However, the nation's forecasting ability using the hydrodynamic and water quality model is still in its infancy. For example, when fire occurred at the petrochemical plant in Kimcheon in 2008, forecasting error of arrival time for phenol prevented intake plants from taking proper measures in advance. In particular, as river flow characteristics have greatly changed following the construction of the weirs in four major rivers, we need to take into account weir management for prompt water pollution accident response. To this end, National Institute of Environmental Research developed the Water pollution Accident Response Management System (WARMS) for four major rivers. This system is designed not only to forecast arrival time and diffusion concentration in a timely manner using its automatic update of EFDC hydro module, but also to conduct scenario modeling using weir-connected operation. This study introduces the WARMS characteristics and evaluates the performance of the system using a phenol-spill simulation.
