Open WL Archief (OWA)

To investigate the uncertainty attributed from the hydrological model structure, several models with different spatial resolutions and process descriptions were considered in the study. Although there are almost countless numbers of model codes, five codes had been chosen to be representative for the different classifications. They range from the simple, lumped, conceptual NAM, PDM and VHM models over the intermediate conceptual-physically based, distributed WetSpa model to the highly detailed, physically based, fully distributed MIKE SHE model, which accounts for the 3-0 groundwater flow and interacts with a MIKE 11 river model to simulate the physical basis of the groundwater-river flow exchange.
