UK Benchmark 6 (Water Module)

UK Benchmarks

Benchmark 2

description

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

results

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

And graphs of water levels at the centre of every depression:

Benchmark 3

description

Engine 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

results

Results every 2 seconds in the middle of every despression are requested and shown below
