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 spherical cross-section.
A culvert is a line-based constructions.
| Attribute | Unit | Description | Default |
|---|---|---|---|
| CULVERT_DIAMETER | m | The diameter of the culvert. For throughput calculations, the culvert is assumed to have a spherical cross-section. | 1 |
| CULVERT_THRESHOLD | m + datum | The height of the culvert. (When set to a level lower than the terrain for either endpoint of it, the culvert's height is equal to the height of the (highest) terrain under either endpoint.) | 0 |
| CULVERT_N | manning value | The manning value of the culvert's material, which influences the flow speed. | 0,014 |
