The re-usable and transferable method is implemented in the open source software KalypsoNA (KalypsoHydrology) and validated with results of a tidal influenced low lying catchment study.enhttp://rightsstatements.org/vocab/InC/1.0/hydrological numerical modellinglowland hydrologybackwater effectsGeowissenschaftenLandschaftsgestaltung, RaumplanungComputation of backwater effects in low lying (marshland) catchments : a re-usable and efficient method in an open source hydrological modelConference Poster not in Proceedings10.15480/882.342910.15480/882.342910.15480/882.2627Conference Poster
