The Benefits of Continental-Scale High-Resolution Hydrological Modeling in the Detection of Extreme Hydrological Events in China

High-resolution hydrological modeling is crucial for detecting extreme events and understanding fundamental terrestrial processes. However, spatial resolutions in current studies have been mostly constrained to relatively coarse resolution (~10–100 km), they therefore a difficult time addressing flooding or drought issues with fine resolutions. In this study, continental-scale high-resolution framework (0.0625°, ~6 km) driven by remote sensing products was used detect event occurrences China evaluated based on the Variable Infiltration Capacity (VIC) model. The results showed that developed model provided more detailed information than coarser models (a 0.25° 1°), thereby capturing timing, duration, extent of hydrologic regarding 2012 Beijing flood 2009/10 Hai River Basin. Here, total water storage changes were calculated VIC (−0.017 mm/year) Gravity Recovery Climate Experiment (GRACE) satellite (−0.203 reflect availability caused climate change anthropogenic factors. This study found 0.0625° dataset could capture changes, providing reliable during events. integrated be accurate evaluations can valuable its long-term occurrence resource security.
