Card Description: Boundary condition control, parameters may be specified by

node or by continuity line number, for which sediment concentration will be

specified. Initial and dynamic solutions.

specified by continuity line number for which

concentration will be specified. Initial and dynamic

solutions.

Option 2: Boundary condition control parameter

specified by node number.

Node or continuity line number

Sediment Concentration (kg/m3)

IBCFACT

0,1

Switch for boundary buffering; 0 off, 1 on

blank

Default = 0

BCFACT

Boundary buffering chamber mixing factor

Default = 0 is the only option at this time

NOTE: GCL card must precede BCL card type.

EXAMPLE: To calculate total mass contribution (kg) from a BCL boundary

specification:

(CONC kg/m3) x (Discharge m3/sec) x (#TimeSteps) x (deltaT hr) x (60 min/hr) x

(60 sec/min) = MASS in kg

Helpful unit conversions:

1 ppm = 1 mg/liter = 0.001 kg/m3

1 ppt = 1 x 10-6 kg/m3
