Constituents:Nutrient Sub Module (NSM) Constituents, Aquifer Environment File

There are a few files that specify the nutrient models setup outside of the mapping table files (.cmt, .smt). These are primarily the aquifer environment file and the point source file.

NSM is currently in no release version of GSSHA.

The Aquifer Environment File

The aquifer environment file is set up to look much like a mapping table. The file has the header

AQUATIC_ENV_NSM10

followed by two index map specifier cards. These index maps do not need to be referenced in the mapping table files to be valid here.

OV_MAP  "ov_map.idx" "map name here"
ST_MAP  "st_map.idx" "map name here"

These index map specifiers are followed by the more typical mapping table entries:

NUM_IDS ##
Text line .....
ID    ##

The main difference here being that the ID lines do not have a list of parameter values, but rather the parameter values follow on the next line or lines.

There are two options for specifying the aquifer environment paramter values. The first is to simply put:

DEFAULT

on the line following the ID. This assumes that all default parameter values are applicable. The other option is to specify all of the parameter values. This comprises 11 lines of values.
