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 | Description |
|---|---|
| A | Unsubmerged entrance and exit. Critical flow at entrance. Upstream controlled with the flow control at the inlet. |
| B | Submerged entrance and unsubmerged exit. Orifice flow at entrance. Upstream controlled with the flow control at the inlet. |
| C | Unsubmerged entrance and exit. Critical flow at exit. Upstream controlled with the flow control at the culvert outlet. |
| D | Unsubmerged entrance and exit. Sub-critical flow at exit. Downstream controlled. |
| E | Submerged entrance and unsubmerged exit. Full pipe flow. Upstream controlled with the flow control at the culvert outlet. |
| F | Submerged entrance and exit. Full pipe flow. Downstream controlled. |
| G | No flow. Dry or flap-gate active. |
| H | Submerged entrance and unsubmerged exit. Adverse slope. Downstream controlled. |
| J | Unsubmerged entrance and exit. Adverse slope. Downstream controlled. |
| K | Unsubmerged entrance and submerged exit. Critical flow at entrance. Upstream controlled with the flow control at the inlet. Hydraulic jump along culvert |
| L | Submerged entrance and exit. Orifice flow at entrance. Upstream controlled with the flow control at the inlet. Hydraulic jump along culvert. |
