Numerical River Modelling
River Rhine "Mehrum" Section Case Study

This Web page describes the basic tasks to set-up a 1D model and a 2D model of a section of the river rhine, a 2D model for the polder "Mehrum" and combined model of the river and the polder for a dam break scenario.

Geometry/Bathymetry

River Cross Section / Bathymetry

• Rhein_punkte.txt (river cross section points)

• dgmfull.e00 polder Mehrum region DEM
• PolderMehrumMesh.dat (polder Mehrum mesh point data - former project)

Polder Mehrum

• polderxyz_10m.dat
• PolderMehrumMesh.dat (polder Mehrum DEM)
• dgmfull.e00 full region DEM

Tools for Geometric Data Handling and Analysis

• transformation to Mike11 format
  • RheinToMike11Application.java (java application to convert Rhein_punkte.txt)
  • Mike11.txt (resulting cross section file Mike11, all cross sections)
• transformation to ArcGIS
  • RiverRheinGIS.html (tutorial and additional data for ArcGIS application)

Time Series

Upstream: Station Ruhrort

• HYMOG_End_Ruhrort-Rhein_Q_01h.uvf
• HYMOG_End_Ruhrort-Rhein_W_01h.uvf

Downstream: Station Wesel

• HYMOG_End_Wesel-Rhein_Q_01h.uvf
• HYMOG_End_Wesel-Rhein_W_01h.uvf

H/Q relationships

• RuhrortHQ.xls (Excel file with several 10 year H/Q tables since 1958)
• WeselHQ.xls (Excel file with several 10 year H/Q tables since 1958)

Tools for Time Series Data Handling and Analysis

pre-analysis with R
