Land use and land cover data (LULC) play an important role in watershed hydrology and environmental modeling. The study of impacts of LULC on hydrologic processes requires the development of hydrologic models that can describe the dynamic effect of LULC and other physical data on hydrology. This study introduces a new method that unites a hydrologic model using physical infiltration mechanisms with a combination of a hydrologic soil group (soil) and a land use and treatment class (cover) information by adjusting the saturated hydraulic conductivity to integrate LULC data information into hydrological modeling. The new method has been incorporated into the Watershed Environmental Hydrology (WEHY) model to simulate hydrologic conditions over the Cache Creek Watershed (CCW) and Shasta Dam Watershed (SDW) in Northern California. This approach can also be used for estimation of the impact of changes in LULC on hydrologic response under future climate conditions. The results of this study suggest that the proposed approach can provide a fine resolution soil dataset through integration of LULC and soil data, which can improve the soil hydraulic parameters and the performance of WEHY model over the target watersheds. Within this framework, the new approach of this study can be applied widely in many parts of the world by means of the global soil data (World Soil Information).
