Subsurface drains can be simulated with either SUPERLINKS and/or a simple link/node routing package. The inputs are similar
3.12.1 Specifying the Methods
The following card is REQUIRED for the simulation of SUPERLINK subsurface drains.
| Card |
Argument |
Description
|
STORM_SEWER |
filename.spn |
Card specifies that subsurface drainage be performed and identifies the input file that describes the newtork connectivity and physical description.
|
The following card is REQUIRED for the simulation of non-SUPERLINK subsurface drains.
| Card |
Argument |
Description
|
STORM_DRAIN |
filename.spn |

3.12.2 Optional Inputs
The following cards are REQUIRED for the simulation of subsurface drains.
| Card |
Argument |
Description
|
GRID_PIPE |
filename.gpi |
File that contains the information needed to link the network to the groundwater model. Required when simulating tile drains.

SUPERLINK_C_OPT |
none |
Specifies that GSSHA assigns the proper node spacing for within superlinks.
|
SUPERLINK_DRAINMOD |
none |
Specifies the method used in DRAINMOD be used to compute flows into tile drains.
