Thank you for your reply.

One further question and one further verification:

Scenario: one 100' long, 4' diameter pipe discharging into a 5' deep, 200' long open channel. Bottom of the channel elevation = 100 ft

Question: what would the following input parameters be to model this situation, taking into account there is no ponding, surcharging or storage at the junction?

Pipe Link:

Shape = Pipe
Barrels = 1
Diameter = 4
Length = 100
Inlet invert offset = 0
Outlet invert offset = ?

Junction

Invert elevation = 100
Max depth = ?
Initial depth = 0 (assume channel and pipe are empty)
Surcharge depth = ?
Ponded area = ?

Channel Link

Shape = Open Channel -- Rectangular
Height = 5
Width = 10
Length = 200'
Inlet invert elevation = 100
Outlet invert elevation = 95


Verification: if a max depth of 0 is used in the junction dialog box, then StormNet will default and use the depth of the connecting links.

For example: a 4' pipe connecting to a junction with a max depth of 0 entered, would (and shows in profile plot) use 4' as the depth in the behind the scenes calculations of HGL.
