Wflow_sbm is a distributed hydrological model developed by Deltares, written in Julia. Initially based on the topog_sbm concept, it aims to balance between low-resolution, low-complexity (conceptual) and high-resolution, high-complexity (physics-based) hydrological models. Achieving this balance involves parameters grounded in physical characteristics or processes, maintaining relatively fast run times. The model encompasses various hydrological processes including glacier and snow dynamics, lakes and reservoirs (including operations), evapotranspiration, unsaturated zone dynamics, lateral subsurface flow, and multiple surface flow routing modules.
