Short Description of Functionality
The program LZKSF is a postprocessor for different numerical models (e.g. TRIM2D, TRIM3D, TELEMAC2D, UNTRIM, UNTRIM2007 etc.). LZKSF automatically computes several characteristic numbers of salinity, suspended load, tracer load, temperature, bed load transport or eff. bed shear stress which are independent of the presence of tides. The data must be given as timeseries (in universal direct access data format). They can be defined in a 3Dvolume, on a 2Darea, along profiles or at specific locations. Data may be the output from either depth integrated (2D) or depth structured (3D) numerical simulations.
The results of LZKSF analyses may be visualised/displayed with the graphical postprocessors HVIEW2D (for 2D/3Ddata), VVIEW2D (vertical sections along profiles) or LQ2PRO (for profiledata).

 grid for 2D/3Ddata (filetype gitter05.dat/bin or filetype untrim_grid.dat)
 or profiletopography for profiledata (filetype profil05.bin)
 or system file for specific locations (filetype location_grid.dat)
OutputFiles
 results of data analyses (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
 informative printer file (filetype lzksf.sdr)
 (optional) trace of program execution (filetype lzksf.trc)
Methodology
An arbitrary long/short period of time can be chosen to calculate characteristic numbers of salinity, suspended load, tracer load, temperature, bed load transport or eff. bed shear stress which are independent of tides. For every node of the grid the given timeserie is analysed automatically by means of several analyses modules. An (optional) calculation for the maximum values of the increase or decrease of salinity takes into account an averaging process of the respective salinities for a userdefined time intervall (typically 30 minutes). Drying and wetting of computational nodes is correctly taken into account.
