C40 COHESIVE SEDIMENT PARAMETER SET 2 REPEAT DATA LINE NSED TIMES

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

*

* IWRSP: 0 USE RESUSPENSION RATE AND CRITICAL STRESS BASED ON PARAMETERS

*                 ON THIS DATA LINE

*            >0 USE BED PROPERTIES DEPENDEDNT RESUSPENSION RATE AND CRITICAL

*                 STRESS GIVEN BY EFDC FUNCTIONS CSEDRESS,CSEDTAUS,CSEDTAUB

*                 FUNCTION ARGUMENSTS ARE (BDENBED,IWRSP)

*             1 HWANG AND MEHTA - LAKE OKEECHOBEE

*             2 HAMRICK'S MODIFICATION OF SANFORD AND MAA

*             3 SAME AS 2 EXCEPT VOID RATIO OF COHESIVE SEDIMENT FRACTION IS USED

*             4 SEDFLUME WITHOUT CRITICAL STRESS

*             5 SEDFLUME WITH CRITICAL STRESS

*      >= 99 SITE SPECIFIC

* IWRSPB:0 NO BULK EROSION

*               1 USE BULK EROSION CRITICAL STRESS AND RATE IN FUNCTIONS

*                  CSEDTAUB AND CSEDRESSB

* WRSPO: REF SURFACE EROSION RATE IN FORMULA

* WRSP=WRSP0*( ((TAU-TAUR)/TAUN)**TEXP ) (gm/m^2/sec)

* TAUR: BOUNDARY STRESS ABOVE WHICH SURFACE EROSION OCCURS (m/s)**2

* TAUN: (NOT USED, TAUN=TAUR SET IN CODE)

* TEXP: EXPONENT OF WRSP=WRSP0*( ((TAU-TAUR)/TAUN)**TEXP )

* VDRRSPO: REFERENCE VOID RATIO FOR CRITICAL STRESS AND RESUSPENSION RATE

* IWRSP=2,3

* COSEDHID: COHESIVE SEDIMENT RESUSPENSION HIDING FACTOR TO REDUCE COHESIVE

* RESUSPENSION BY FACTOR = (COHESIVE FRACTION OF SEDIMENT)**COSEDHID

*
