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) originates from the IMPACT project (Soares-Frazão and Zech 2002). Physical measurements were provided by the Civil Engineering Laboratory of the Université Catholique de Louvain (UCL).

Characteristics:

  • Dimensions: 20X the values below
  • Roughness: uniform Manning n = 0.05 s/m^(1/3)
  • Initial 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). The results for each point are shown below.
