CI CARD: Clay Characteristics By ID
Required for Clay
Card Description: Active parameters on this card cause the program to use the
specified parameter values in place of the default values
0, C 1-2
Card group identifier.
ID type number
(#1 is freshly deposited and unconsolidated)
If IDCL > MNCL (CC card) do not consolidate
Typical layer thickness (m) for this id type
Default = .03 meters
Bed shear stress at which cohesive particles begin to
erode (Newtons/sq m)
Default = 0.06 n/m2
Erosion rate constant for particle erosion
Default = 0.002 kg/m2/sec
Bed shear stress at which cohesive layers begin to
erode in mass (newtons/m2)
Default = 0.06, .12, .41, and 3.4 for layers 1 through
4 and 3.4 (n/m2) for layers 5 through MNCL
Bed shear stress at which cohesive at age = 1 year
begin to erode in mass (n/m2)
Default = 1.1 x QSI values (see above)
Initial dry density of a deposit of this type of
cohesive material (kg/m3)
Default = 90, 108, 144, and 263 for layers 1 through
4 and 402 for layers type 5 through MNCL
The consolidated dry density of deposits of this type
of cohesive material at age = 1 year.
Default = 1.1 times default values for RHOI (above)
RHOE and QSE to time in years
CCC=reference time (days) for QSE and RHOE
NOTE: Values of the variables in Fields 5-8 vary widely among sediment types.
The default values may be wrong for a given sediment. ID types are numbered such
that the highest number is the deepest core.
NOTE: CC card should precede CI cards.
