SA CARD: Sand Characteristics
Required for Sand
Card Description: Active parameters on this card cause the program to use the
specified parameter values in place of the default values.
Field

0, C 1-2
IC1
SA
Card group identifier.
Ackers-White transport function. This is the only
1
MTC

option available in the current version of SED2D
WES.
≥0
2
SACLL
Minimum sand grain size for NSACI
<0
Default = 0.0625 mm. See note below.
≥0
3
SACUL
Maximum sand grain size for NSACI
<0
Default = 0.0625 mm. See note below.
+
Class number. The class interval is calculated for
4
NSACI
the log of particular sizes. See note below
≥0
5
SGSA
Specific gravity of sand grains
<0
Default = 2.65
≥0
6
GSF
Grain shape factor
This variable name is basically not used.
<0
Default = 0.67
≥0
7
CLDE
Characteristic length factor for deposition
<0
Default = 1 times the depth
≥0
8
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.
