2.1.2. DXDY Input FileΒΆ

The dxdy.inp file specifies many of the physical properties of each cell. Every cell described in the cell.inp file must be described in this file.

Variable Description
I Array index in x direction
J Array index in y direction
DX Cell dimension in x direction, meters
DY Cell dimension in y direction, meters
DEPTH Initial water depth, meters
BOTTOM ELEV Bottom bed elevation, meters
ZROUGH Log law roughness height, zo, meters
VEG TYPE Vegetation type class, integer value

Below is part of a sample input file that specifies part of a single column of the geometry.
