This Web page describes the course work of the course "numerical simulation - river modelling". Main tasks are a 1D model and a 2D model of the river Rhine section Ruhort - Wesel, a 2D model for the polder Mehrum and a combined model of the river and the polder for flood modelling purposes. The course work is structured by modellng steps integarted in assignments. Most parts are done as team work.
Do a pre-analysis for the given data (geospatial data, hydraulic measurement data)
Software tool could be GIS, Excel, R, Matlab, paraview or similiar tools.
Set-up a 1D Model for the rhine section between Ruhrort and Wesel.
Software tool could be Mike11, HecRas or similiar 1D river simulation products.
Set-up a 2D Model for the rhine section between Ruhrort and Wesel.
Software tool could be Mike21FM, Telemac or similiar 2D river simulation products.
Set-up a 2D Model for the polder Mehrum and the related flooding process. Software tool could be Mike21FM, Telemac or similiar 2D river simulation products.
Combine the 1D model of the river Rhine section and the 2D polder model with for a dam break scenario. Both models can be coupled by a Q/H relationship or simplifed by a Q(t) function (outflow 1D model, inflow 2d model).
Finally a full 2D model for the river section and the polder could be used to model the flooding of the polder for a dam break scenario (fixed, predfined geometry).
The main assignment covers working step 1 + 2. Each student has to do the basic work personally, the case study detailed work is done as team work. Details of the assignment are descripbed on the Assignment Web page. Working step 3 to 5 will be demonstrated and is optional for students, who would like to specialize in these topics.
