Sample Case P8_DEMO.P8P
Illustrates various device types running in parallel.  Each has its own watershed ( not shown, for simplicity)
Surface outlets (normal pool & spillway) are all routed to a pipe device that collects all runoff.
Infiltration from each device and each watershed is routed to an aquifer.
The aquifer provides baseflow to a stream (represented by a Pipe device)
Baseflow and runoff pipes are combined to another pipe representing combined outflow from the watershed
