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.
