Cover Story: Increasing extreme weather events necessitate accurate flood prediction to protect lives and infrastructure. A study in the Waryong Reservoir Basin revealed significant differences in flood model (Cell2Flood) accuracy depending on rainfall inputs. Researchers evaluated six rainfall datasets, including on-site measurements, Automated Synoptic Observing System (ASOS) and Automatic Weather System (AWS) network data, and radar-based HSR data. Point-gauged ASOS (P-ASOS) data showed the highest reliability (Pearson's r up to 0.84), outperforming the nearest AWS station. Conversely, HSR data underperformed, with large runoff prediction errors (NPE up to 4.66, PTE over 200 minutes). Input-specific calibration improved the results, but errors persisted due to inherent rainfall data uncertainty. This highlights the importance of careful rainfall input selection and calibration in flood modeling. View this paper
