C42 NON-COHESIVE SEDIMENT PARAMETER SET 2 REPEAT DATA LINE NSND TIMES

* DATA REQUIRED IF NSND>0, EVEN IF ISTRAN(7) = 0

*

* ISNDEQ: >1 CALCULATE ABOVE BED REFERENCE NON-COHESIVE SEDIMENT

*                     EQUILIBRIUM CONCENTRATION USING EFDC FUNCTION

*                     CSNDEQC(SNDDIA,SSG,WS,TAUR,TAUB,SIGPHI,SNDDMX,IOTP)

*                     WHICH IMPLEMENT FORMULATIONS OF

*                  1 GARCIA AND PARKER

*                  2 SMITH AND MCLEAN

*                  3 VAN RIJN

*                  4 SEDFLUME WITHOUT CRITICAL STRESS

*                  5 SEDFLUME WITH CRITICAL STRESS

* ISBDLD: 0 BED LOAD PHI FUNCTION IS CONSTANT, SBDLDP

*               1 VAN RIJN PHI FUNCTION

*               2 MODIFIED ENGULAND-HANSEN

*               3 WU, WANG, AND JIA

*               4 (NOT USED)

*               5 (NOT USED)

* TAUR: CRITICAL STRESS IN (m/s)**2

*            NOTE: IF TAUR < 0, THEN TAUR AND TAUN ARE INTERNALLY

*            COMPUTED USING VAN RIJN'S FORMULAS

* TAUN: EQUAL TO TAUR FOR NON-COHESIVE SED TRANS

* TCSHIELDS: CRITICAL SHIELDS STRESS (DIMENSIONLESS)

* ISLTAUC: 1 TO IMPLEMENT SUSP LOAD ONLY WHEN STRESS EXCEEDS TAUC FOR EACH GRAINSIZE

*                 2 TO IMPLEMENT SUSP LOAD ONLY WHEN STRESS EXCEEDS TAUCD50

*                 3 TO USE TAUC FOR NONUNIFORM BEDS, THESE APPLY ONLY TO RESUSPENSION

* FORMULAS NOT EXPLICITLY CONTAINING CRITICAL SHIELDS STRESS SUCH AS G-P

* IBLTAUC: 1 TO IMPLEMENT BEDLOAD ONLY WHEN STRESS EXCEEDS TAUC FOR EACH GRAINSIZE

*                 2 TO IMPLEMENT BEDLOAD ONLY WHEN STRESS EXCEEDS TAUCD50

*                 3 TO USE TAUC FOR NONUNIFORM BEDS, THESE APPLY ONLY TO BED LOAD

* FORMULAS NOT EXPLICITLY CONTAINING CRITICAL SHIELDS STRESS SUCH AS E-H

* IROUSE: 0 USE TOTAL STRESS FOR CALCULATING ROUSE NUMBER

*               1 USE GRAIN STRESS FOR ROUSE NUMBER

* ISNDM1: 0 SET BOTH BEDLOAD AND SUSPENDED LOAD FRACTIONS TO 1.0

*               1 SET BEDLOAD FRACTION TO 1. USE BINARY RELATIONSHIP FOR SUSPENDED

*               2 SET BEDLOAD FRACTION TO 1, USE LINEAR RELATIONSHIP FOR SUSPENDED

*               3 USE BINARY RELATIONSHIP FOR BEDLOAD AND SUSPENDED LOAD

*               4 USE LINEAR RELATIONSHIP FOR BEDLOAD AND SUSPENDED LOAD

* ISNDM2: 0 USE TOTAL SHEAR VELOCITY IN USTAR/WSET RATIO

*               1 USE GRAIN SHEAR VELOCITY IN USTAR/WSET RATIO

* RSNDM: VALUE OF USTAR/WSET FOR BINARY SWITCH BETWEEN BEDLOAD AND SUSPENDED LOAD

*
