Short Description of Functionality

The program LZKWF is a postprocessor for different numerical models (e.g. TRIM-2D, TRIM-3D, TELEMAC-2D, UNTRIM, UNTRIM2007 etc.). LZKWF automatically computes several characteristic numbers of water level which are independent of the presence of tides. The data must be given as time-series (in universal direct access data format). The results of LZKWF analyses may be visualised/displayed with the graphical postprocessors HVIEW2D (for 2D/3D-data) or LQ2PRO (for profile-data).

Within the period of data analysis the following characteristic numbers (independent of tides) can be (optionally) calculated:

Input-Files

  1. general input data (filetype lzkwf.dat)
  2. time series data which shall be analysed (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
  3. grid for 2D/3D-data (filetype gitter05.dat/bin or filetype untrim_grid.dat)
or profile-topography for profile-data (filetype profil05.bin)
or system file for specific locations (filetype location_grid.dat)

Output-Files

  1. results of data analyses (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
  2. informative printer file (filetype lzkwf.sdr)
  3. (optional) trace of program execution (filetype lzkwf.trc)

Methodology

An arbitrary long/short period of time can be chosen to calculate characteristic numbers of water level which are independent of tides. For every node of the grid the given time-serie is analysed automatically by means of several analyses modules. An (optional) calculation for the maximum values of the velocities for fall and rise of the water surface takes into account an averaging process of the respective velocities for a user-defined time intervall (typically 30 minutes).

For visualization of results with alternative bathymetry some additional results of program LZKMF are required.
Namely

These quantities must be available for the same period of data analysis.
