Introduction


  • Advice on SX connections & number of cells to connect to 2D domain – implications
  • Flow regimes – theory behind each.
  • How to check for the flow regime – link to check file
  • How do we sub divide logic rules (operational culverts)*
  • Losses – fixed, Englehund, automatic manholes etc.
  • Provide some justification on the ‘default’ height/width, entry/exit losses.


Flow Regimes

Regime / suffix Description
