porosity values are initially set to 1.0 over the entire grid. The program then uses
values within the porous region boundaries to values specified by the user. The
(x,y) coordinates of the porous region boundaries are stored as two columns of
data in an ASCII file. The program is run interactively from an MS-DOS
command prompt window. An example is as follows:
C:\bouss2d\bin\map_porosity
bathy
# name of input bathymetry file (.grd)
porosity
# name of output porosity file (.grd)
2
# number of porous regions [1]
bw1.xy
# name of boundary file for porous region #1 [.xy]
0.4
# porosity (0-1) [0.4]
bw2.xy
# name of boundary file for porous region #2 [.xy]
0.4
# porosity (0-1) [0.4]
The porosity file is written out as an ASCII file in the grid file format described in
Appendix D.
