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

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
