- Integrated modeling approaches are essential for understanding and mitigating extreme hydrometeorological events and their associated disaster impacts under changing climate conditions. This study integrates the Weather Research and Forecasting (WRF) model with WRF-Hydro into a coupled modeling framework to assess climate change impacts on extreme hydrometeorological events and to quantify the resulting flood disaster risks. This coupled approach enables seamless integration of atmospheric and hydrological processes through synchronized exchange of surface conditions and physical parameters, providing a comprehensive basis for disaster impact analysis. This research focuses on Typhoon Hinnamnor, which brought record-breaking rainfall, severe flooding, and significant socioeconomic damage to South Korea in 2022. The study area includes the Nakdong and Geum River basins, as well as the eastern coastal regions (Pohang, Uljin). Multiple WRF simulations with various microphysics schemes are conducted to determine the optimal configuration, and hydrological simulations using both ground-based and WRF-generated forcings are analyzed to evaluate hydrological responses. Furthermore, flood inundation analysis, flood frequency and return period estimation, and a disaster vulnerability assessment incorporating land use, population density, and critical infrastructure exposure are performed to evaluate flood risk under current and future climate scenarios. Extreme hydrometeorological conditions under climate change scenarios are assessed based on key variables such as typhoon trajectory, precipitation, wind speed, soil moisture, and streamflow. The discussion highlights the benefits and challenges of the coupled modeling approach and its applicability for disaster impact assessment in vulnerable regions of South Korea.
