SACLL
Minimum sand grain size for NSACI
Default = 0.0625 mm. See note below.

NSACI
Class number. The class interval is calculated for the log of
particular sizes. See note below

SGSA
Specific gravity of sand grains

GSF
Grain shape factor
<0
Default = 0.67

CLDE
Characteristic length factor for deposition

CLER
Characteristic length factor for erosion
<0
Default = 10 times the depth
NOTE: The current version of SED2D-WES handles only one size class. Therefore NSACI must equal 1, and
SACLL must equal SACUL. A multiple grain size algorithm is under development.
