Richards Equation

Modeling of surface runoff, infiltration and evapotranspiration – A research report by National Institute of Hydrology

In this study, a model has been developed considering surface flow component and subsurface flow component along with the evapotranspiration from the crop as the sink term for the Lokapavani area of KR Sagar command of Karnataka. The surface flow component is represented using one-dimensional St-Venant equations and the subsurface flow component is represented using one-dimensional Richards equation with the sink term for the evapotranspiration from crop.Read More

Overland flow modeling for urban catchment considering random roughness coefficient and irregular land surface – A research report by National Institute of Hydrology

In this study, a two-dimensional overland flow model has been developed considering random roughness coefficients and irregular land surface for the analysis of surface flow component. The one-dimensional Richards equation for subsurface flow component has been used for calculating the infiltration from the pervious area.Read More
