C37 BED MECHANICAL PROPERTIES PARAMETER SET 1

* DATA REQUIRED IF NSED>0, EVEN IF ISTRAN(6) = 0

*

* SEDSTEP: SEDIMENT BED INTERACTION TIME STEP (SECONDS)

*SETSTART: START TIME FOR BED/WATER COLUMN INTERACTION (DAYS)

* IBMECH: 0 TIME INVARIANT CONSTANT BED MECHANICAL PROPERITES (UNIFORM BED ONLY)

*                1 SIMPLE CONSOLIDATION CALCULATION WITH CONSTANT COEFFICIENTS

*                2 SIMPLE CONSOLIDATION WITH VARIABLE COEFFICIENTS DETERMINED

*                   EFDC FUNCTIONS CSEDCON1,2,3(IBMECH)

*                3 COMPLEX CONSOLIDATION WITH VARIABLE COEFFICIENTS DETERMINED

*                   EFDC FUNCTIONS CSEDCON1,2,3(IBMECH). IBMECH > 0 SETS THE

*                   C38 PARAMETER ISEDBINT=1 AND REQUIRES INITIAL CONDITIONS

*                   FILES BEDLAY.INP, BEDBDN.INP AND BEDDDN.IN

*               9 TYPE OF CONSOLIDATION VARIES BY CELL WITH IBMECH FOR EACH

*                   DEFINED IN INPUT FILE CONSOLMAP.INP

* BEDPORC: CONSTANT BED POROSITY (IBMECH=0, OR NSED=0)

*                    ALSO USED AS POROSITY OF DEPOSITIN NON-COHESIVE SEDIMENT

* SEDMDMX: MAXIMUM FLUID MUD COHESIVE SEDIMENT CONCENTRATION (MG/L)

* SEDMDMN: MINIMUM FLUID MUD COHESIVE SEDIMENT CONCENTRATION (MG/L)

* SEDVDRD: VOID RATIO OF DEPOSITING COHESIVE SEDIMENT

*                  > 0 CONSOLIDATE OVER TIME TO SEDVDRM

*                  = 0 CONSOLIDATE INSTANTANEOUSLY TO SEDVDRM (0.0>=SEDVDRT<=0.0001)

*                  < 0 CONSOLIDATE TO INITIAL VOID RATIOS
