Development and Application of an Interactive Coupling Rainfall-Runoff Model According to Soil Texture

In this study, we developed a model that simulates surface and subsurface flows for rainfall-runoff analyses using an interactive coupling method. To characterize the interaction between the surface and subsurface flows, we studied the coupling analysis model. The proposed model was designed followi...
