Hydrodynamic numerical model TRIM-2D<br />
Position dependant soil classification numbers<br /> 
|shortdescription=The program MKRDAT creates a file, which contains soil classification numbers for each u and v point of the TRIM-2D grid. To do this, the program needs the following input: First a TRIM-2D grid and second information about the position dependency of the soil classifications. The classification numbers can be set inside areas (discribed by a closed polygon i.e. '''structures INSEL or SAND''') and optional pointwise. 
|inputfiles=
# General input data (filetype [[MKRDAT.DAT|mkrdat.dat]]).
# TRIM-2D-Bathymetry (filetype [[TR2.TOPO.BIN.IND|tr2.topo.bin.ind]]).
# (optional) files(s) containing the polygons describing an area (type [[INSEL.DAT|insel.dat]]).
# (optional) point by point assignment of '''soil classification numbers''' (filetype [[GKPUNKT.DAT|gkpunkt.dat]]). 
|outputfiles=
# Distribution of '''soil classification numbers''' (filetype [[TR2.SOIL.BIN.IND|tr2.soil.bin.ind]]).
# when test output is active: mkrdat.trc and file of type [[TR2.TOPO.BIN|tr2.topo.bin]] with the classification numbers as TRIM-2D-'''topography file''' (enables visualization with [[TRGITTER05]]). 
|methodology=
'''Point by point assignment of soil classification numbers'''
All points defined by the user in a file of type [[GKPUNKT.DAT|gkpunkt.dat]] must pass through the folling steps:
* Read the coordinates, the depth and the soil classification number
* Compute the grid indices of the associated model point
* Control the position of the model point (inside/outside of model area; wet/dry model point)
* Copy the soil classification number to the u and v edge of this model point 
'''assignment of soil classification numbers by area'''
* The selected areas are searched by name in the given structure files. Only structures of type INSEL and SAND are accepted during the search.
* When an area is found it is processed. Therefor the order of the structure files and areas inside the input file is significant.
* The classification numbers are assigned then with respect to the criterions set by the user.
* The control criterions are: is the point inside/outside the area and deeper/lower than a depthlimit?. 

All grid edges not touched by this assignment get the soil classification number 1.
