This [[Water Module benchmarks|benchmark]] performs ''UK EA benchmark Test 6 – Dambreak'' using the [[Water Module]] of the {{software}}.
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.

This dambreak test case (see Appendix A.6 for details) is the original benchmark test case available from the IMPACT project (Soares-Frazão and Zech 2002), for which measurements from a physical model at the Civil Engineering Laboratory of the Université Catholique de Louvain (UCL) are available.
Engine version: 2019.0.0 DEV 66.0
Date executed: 2018-07-10
 
Characteristics:
A test for the evaluation of an inundation pattern and depth at low momentum over a complex topography:
* Dimensions: 2000m X 200m
* Roughness: uniform manning = 0,03 m/s1/3
* Initial conditions: empty grid
* Resolution: 20m grid
* Boundary condition: Q(t) in North-East side of the model domain
 
note: the benchmark was executed on a 10m, instead of 20m

Water levels every 300 secs on the centre of every depression are requested together with a map of the waterdepts at the end of simulation.
 
The waterdepth at the end of simulation is shown below

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

This benchmark performs UK EA benchmark Test 6 – Dambreak using the Water Module of the Tygron Platform.

This dambreak test case (see Appendix A.6 for details) is the original benchmark test case available from the IMPACT project (Soares-Frazão and Zech 2002), for which measurements from a physical model at the Civil Engineering Laboratory of the Université Catholique de Louvain (UCL) are available.

Characteristics:

  • Dimensions: 20X the values below
  • Roughness: uniform manning = 0,05 m/s1/3
  • Initiële conditions: 8m in reservoir, 0,4m in floodplain
  • Modelgrid resolution: 2m

Results

Measured water levels and velocities were provided by UCL for six points (G1 to G6, except for velocities at G6). Below the result for each point.
