GC CARD
GEOMETRY, CONTINUITY CHECK LINES
GC CARD
Code corner nodes only. Code all lines in the same direction. The lines will be numbered (J = 1, number
of lines) according to their order of appearance in this file.
Automatic calculation of the sediment flux across a continuity check line is not available in current version of
SED2D-WES. At some future date the capability will be added to calculate flux at up to MCC lines across part or
all the grid with up to MCCN nodes per line. The flux through the first continuity check line that is specified will
be used as a reference load for all subsequent continuity lines (as in RMA2). Code all lines in the same direction to
ensure a consistent sign for the flux direction. . In general, code left to right when facing downstream.
