Modelling tools


PCRaster is software for building probabilistic, forward, spatio-temporal modelling. It provides facilities for data assimilation. Model building is done in Python by using a framework for forward simulation and combining spatial operations which have been implemented in C++. It is maintained since 1990 by our team.


LUE is software for storing and manipulating large amounts of information for large numbers of objects. The LUE physical data model can be used for storing continuous fields and discrete agents, for example. It is developed by our team.



PCR-GLOBWB is a global hydrological model developed by the Global Hydrology Group. Our team is closely cooperating with the group and involved in maintenance of the PCR-GLOBWB code and improvements under the hood as it is coded in PCRaster.


PYCATCH is a catchment modelling framework coded in PCRaster. It contains modules for hydrological and geomorphological processes. It runs at spatial resolutions between 1 m and 100 m and temporal resolutions between 1 h and 1 week. There is no formal documentation yet. For hydrological applications, please refer to Lana-Renault et al., 2013. For geomorphological applications, refer to Karssenberg et al., 2017, in particular the digital supplement providing the model description. For info please contact


PLUC is a land use change model coded in PCRaster. It is developed and maintained by Judith Verstegen who is currently at Muenster University (Germany).
