Headwall Connectivity and Function in Model
Headwalls and Conduits
When a headwall is connected to a conduit it represents the transition from an open channel to a closed channel or vice versa. You can use the headwalls to define inlet/exit structures for a culvert as well.
To do so:
- On the headwall set the "Inlet Description" to the appropriate set Culvert Inlet Coefficients.
- On the connecting Conduit set the "Is Culvert?" flag to true.
- Then specify whether or not to set the culvert inlet coefficient set for upstream and downstream inlets either based on the adjacent headwall or to simply specify on the conduit itself.
Headwalls and Channels
When a channel link connects to a headwall you can specify the shape of the cross section at the interface of the open channel and the headwall structure.
Headwalls and Ponds
A headwall can represent inflow or outflow structure of a pond.
