Setup

The spatial domain consists of a rectangular

  (1)

where is the bed elevation and is the horizontal distance.

Model Setup

A computational grid with constant water depth of 5 m and irregular boundaries is used in order to test the model performance. The computational grid has 60 columns and 70 rows and a constant resolution of 500 m.

Figure 1. Computational grid.


Results
