Domain

  • Square reservoir and a 45 deg bend channel
  • Reservoir length = 2.44 and width = 2.39 m
  • Straight channel length = 4.25 m and width = 0.495 m
  • Angled channel length = 4.15 m and width = 0.495 m

Wet dam bed dimensions

Initial Conditions

  • Initial reservoir water depth = 0.25 m
  • Initial channel water depth = 0.01 m
  • Friction defined by Manning's
    • flume bottom n = 0.0095
    • flume side wall n = 0.0195
