Development and Evaluation of a Real-Time Flood Forecasting System Based on the K-series Integrated Modeling Framework in the Seomjin River Basin

This study evaluates the applicability of a real-time flood forecasting system developed using K-water’s K-series integrated modeling framework, which couples rainfall-runoff simulation, reservoir operation, river hydraulics, and flood inundation analysis. The system was applied to the extreme flood event that occurred in the Seomjin River Basin, South Korea, in August 2020. Catchment runoff was generated using K-DRUM (K-water Distributed Rainfall Runoff Model), reservoir operations were simulat
