1D2D model of the lower Rhine and the upper Dutch Rhine branches between Andernach and Nijmegen, Arnhem and Zutphen
GRADE (Generator for Rainfall and Discharge Extremes) is a chain of models, containing a rainfall generator, a hydrological model and a hydrodynamic model. In 2014 this model instrument was built for the Rhine until Lobith and the Meuse until Eijsden in order to determine the statistics of the discharge entering the Netherlands at Lobith (Rhine) and Eijsden (Meuse) (GRADE version 2.0 and 2.1). In these version of the model instrument SOBEK-RE is used for hydrodynamic modelling.
