Abstract:Quantification of groundwater recharge is highly important for understanding freshwater systems and sustainable management of both groundwater and surface water bodies, but it is very uncertain. To improve the global‐scale simulation of diffuse groundwater recharge (GWR), we developed, for the first time in global hydrological modeling, an approach for explicitly simulating GWR in karst areas, based on the World Karst Aquifer Map and ground‐based estimates of karst GWR. Ground‐based estimates of both karst and… Show more
