The accurate estimation of soil texture is crucial as it significantly impacts soil moisture and other hydrological variables. While the Weather Research and Forecasting Hydrological Extension (WRF-Hydro) model is a useful tool for investigating various aspects of hydrological processes and their interactions with the atmosphere, the default soil map provided by USGS and MODIS exhibits potential issues associated with coarse resolution and limited accuracy. To address this deficiency, this study conducts a series of sensitivity experiments that consider additional data sources or alternative soil mapping approaches within WRF-Hydro model framework. A comparative analysis is performed by focusing on hydrological variables such as soil moisture and runoff. The study will enhance our understanding of how changes in soil properties influence key hydrological processes and shed light on the impact of diverse soil conditions on the robustness of simulation results.
