Drainage System Layout Errors

A valid drainage system layout must obey the following conditions:

• An outfall node can have only one conduit link connected to it.

• A flow divider node must have exactly two outflow links.

• Under Kinematic Wave routing, a junction node can only have one outflow link and a regulator link cannot be the outflow link of a non-storage node.

• Under Dynamic Wave routing there must be at least one outfall node in the network.

An error message will be generated if any of these conditions are violated.
