Analytical Solution
The purpose of this verification test is to assess the model performance in simulating long wave propagation. The case is also useful for testing the model performance and symmetry for a non-rectangular domain. The test case consists of a quarter annulus shaped domain with a linear bottom in the radial direction. The analytical
Setup
- Forcing: 0.3048 m amplitude M2 tide (red cell string)
- Bottom friction: 0.0 sec/m^(1/3) (Manning N)
- Horizontal eddy viscosity: :0 m^2/sec
- Run duration: 5 days
- Ramp period: 2 days
- Time step: 10 min
- Wall Friction: Off
- Grid resolution: 1000 x 1000 m (constant)
- Number of cells: 23409
Results
The figure below shows a time series of water
levels at the green point shown in the figure above.
