Stromlinienförmiger Netzgenerator für Oberflächengewässermodelle
- recording of the morphology (river with inner zone and embankment, foreshore)
- measurement of the natural flow conditions (water stage, discharge, flow velocities)
- mesh generation and transformation of the morphology to the grid
- model calibration through comparison of measured and calculated flow properties

Procedure
To Apply 2D Numerical Models
Procedure to set up the model
- definition of river strips and cross sections
- differentiate the stream strips with respect to
- foreshore
- inner zone
- embankment
- consideration of embankment bottom and embankment top when generating the mesh
- mesh refinement at the embankment
- areal interpolation and separated interpolation of the river bottom and of the foreshore from measurement data
