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 Card specifies that subsurface drainage be performed and identifies the input file that describes the newtork connectivity and physical description.

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. 
HIGH_HEAD_RELEASE
 none Allow flow back to the overland from the storm drains during system surcharge. 
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.

3.12.3 Output Cards

The following cards are REQUIRED for the simulation of subsurface drains.

Card Argument Description 
SUPERLINK_JUNC_LOCATION
 filename File that defines the junctions for output. 
SUPERLINK_NODE_LOCATION
 filename File that defines the nodes for output. 
SUPERLINK_JUNC_FLOW
 filename File that contains the time series ouput data for the junctions listed in SUPERLINK_JUNC_LOCATION. 
SUPERLINK_NODE_FLOW
 filename File that contains the time series ouput data for the nodes listed in SUPERLINK_NODE_LOCATION.
