UK Benchmark 6 (Water Module)
The Benchmark of the UK Environmental Agency (EA, 2013) is used to assess the functioning of the numerical scheme for several cases. The results are described below.
Benchmark 3
description
Tygron Platform version: 2019.0.0 DEV 68.0
Date executed: 2018-07-11
Characteristics: Test for conservation of momentum over a small obstruction. By inertia (flow changing over time) some water flows over the obstruction.
- Dimensies: zie Figuur below
- Roughness: uniform manning = 0,01 m/s1/3
- Initial condition: 0m water depth
- Resolution: 5m grid
- Boundary condition: Q(t), see figure below
