Short Description of Functionality

The program TRVZR analyses the hydrodynamic files of the numerical methods TRIM-2D and TRIM-3D.

Input-Files

1. general input data (filetype trvzr.dat)
2. bathymetry and index arrays (filetype tr2.topo.bin.ind)
3. Trim-2D or Trim-3D hydrodynamic result files (area) (filetype tr2.result)
4. (opt) boundary polygon to desribe, which cells should be analysed (filetype poly.dat)

Output-Files

1. analyse result files (split into information, results and differences) (filetypes tr_h.Info.dat, tr_h.ergeb.dat and tr_h.delta.dat)
2. (optional) trace of program execution (filetype trvzr.trc)

Methodology

Every Trim-2D or Trim-3D result file contains the calculated water levels for each grid cell for a single date. Further on, for every grid cell the undisturbed water depth is known, so that the program can calculate which cells are flooded and which cells are dropped dry. For all flooded cells the program calculates the extreme water level and water column, the value for the flooded surface and the volume of the water body. All these results are stored in a file of the type tr_h.ergeb.dat.

If there are more than one Trim-2D or Trim-3D result files, then the program can also calculate the time variation of all above result values and stores these results in a file of the type tr_h.delta.dat.
