Abstract
Observed data are required to carry out hydrological simulations in a watershed for use by policy-makers. Hydrological simulations, thus, require extensive interdisciplinary knowledge about modelling, computer sciences, databases and GIS. A MATLAB pre-process prior to the hydrological modelling is presented for educational purposes and for an easy uptake by non-GIS users. Moreover, this allows for parallel computing. This pre-process builds on two renowned and freely available MATLAB toolboxes providing GIS and mesh functionalities. Additional functionalities allow for a decomposition of watersheds with respect to parameterized constraints, including the meshing of the subdomains and the construction of an oriented flow graph. The method is exemplified by a study on a sub-basin of the Saar River.
