Runoff Prediction in Small Rivers Using Dynamic Parameter Fitting with Observed Rainfall Data
(American Society of Civil Engineers, 2024)Floods in a small river basin measuring a few square kilometers can sometimes cause the water levels to rise more than 1 m within 10 min. Therefore, the importance of runoff prediction within tens of minutes is greater in ... -
Rainfall Infiltration Test and Numerical Simulation Analysis of a Large Unsaturated Soil Slope
(American Society of Civil Engineers, 2024)Rainfall infiltration is the primary factor affecting slope stability, which may lead to geological hazards such as landslides, collapses, and debris flows. Thus, it is crucial to investigate the rainfall infiltration ... -
Response of Precipitation Increases to Changes in Atmospheric Moisture and Its Flux in the Columbia River Basin: WRF Model–Based Precipitation Maximization for PMP Studies
(American Society of Civil Engineers, 2024)US probable maximum precipitation (PMP) estimation guidance fundamentally relies on the assumption that any change in precipitable water is consistent with the change in precipitation. While this assumption is theoretically ... -
Generalized Relationship Linking Water Balance and Vegetation Productivity across Site-to-Regional Scales
(American Society of Civil Engineers, 2024)Evapotranspiration (ET) is a pivotal component in catchment-scale water balance and is essential for informed watershed management. Nevertheless, uncertainties in ET observation or modeling have been hindering effective ... -
Applicability of ERA5 Reanalysis Precipitation Data in Runoff Modeling in China’s Ili River Basin
