Culverts are effectively tunnels or pipes directly connecting two bodies of water, and allow water to flow in either direction. Culverts can also be used to model tunnels on land, creating a hole which water can flow through when it is flowing over land. The throughput of a culvert is limited by its dimensions.
Culverts are assumed to have a circular cross-section, and level (i.e. not inclined).
A culvert is a line-based construction.
Icon | Attribute | Unit | Description | Default |
---|---|---|---|---|
CULVERT_DIAMETER | m | The diameter of the culvert. For throughput calculations, the culvert is assumed to have a circular cross-section. | 1 | |
CULVERT_HEIGHT | m + datum | The height of the inner side of the culvert's underside (or the threshold height at which water starts flowing through the culvert). When set to a level below the terrain height at either end-point, the culvert's height will automatically be treated as a value equal to that of the highest terrain found at either of its endpoints. | 0 | |
CULVERT_N | s/(m1/3) | The manning value of the culvert's material, which influences the flow speed. | 0,014 |
Notes
- If a culvert is placed in a waterway, and the waterway is not otherwise interrupted, water will be able to flow past the culvert via the waterway itself. It is recommended to make sure that the waterway is obstructed by an increase in the terrain height in such a way that the only way water can flow from the one end of the culvert to the other is via the culvert.
