Significance of the File

description of local weirs with quadratic friction for DELFT3D

File-Contents (in Catchwords)

Contains location as well as type for sub-grid scale local weir effects in a computational grid of the integrated modeling system DELFT3D; the impact of the weir on the flow is parameterized using a quadratic friction law:

1. the grid co-ordinates of the begin and end point of a local weir;
2. type description
   • U = parameterization for U-computational points (edge in N-direction);
   • V = parameterization for V-computational points (edge in M-direction).
3. friction coefficient for a quadratic friction law used to parametrize localized energy losses;
4. sill depth of the weir.

Notice: Further informations can be found in the Delft3D-Flow user manual, appendix A (local weirs).
