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.
