Short Description of Functionality

The program LZKSF is a postprocessor for different numerical models (e.g. TRIM-2D, TRIM-3D, TELEMAC-2D, UNTRIM, UNTRIM2007 etc.). LZKSF automatically computes several characteristic numbers of salinity, suspended load, temperature or eff. bed shear stress which are independent of the presence of tides. The data must be given as time-series (in universal direct access data format). They can be defined in a 3D-volume, on a 2D-area, 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/3D-data), VVIEW2D (vertical sections along profiles) or LQ2PRO (for profile-data).

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

• Maximum Value of Salinity (HS)
• Minimum Value of Salinity (LS)
• Mean Value of Salinity (MS)
• Maximum Variation of Salinity (DS)
• Maximum Increase of Salinity
• Maximum Decrease of Salinity
• Standard Deviation of Salinity
• Variance of Salinity
• Duration of High Salinity
• Duration of Low Salinity

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

• Maximum Value of Suspended Load
• Minimum Value of Suspended Load
• Mean Value of Suspended Load
• Maximum Variation of Suspended Load
• Maximum Increase of Suspended Load
• Maximum Decrease of Suspended Load
• Standard Deviation of Suspended Load
• Variance of Suspended Load
• Duration of High Suspended Load
• Duration of Low Suspended Load

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

• Maximum Value of Temperature
• Minimum Value of Temperature
• Mean Value of Temperature
• Maximum Variation of Temperature
• Maximum Increase of Temperature
• Maximum Decrease of Temperature
• Standard Deviation of Temperature
• Variance of Temperature
• Duration of High Temperature
• Duration of Low Temperature

Within the period of data analysis the following characteristic numbers of eff. bed shear stress (independent of tides) can be (optionally) calculated:

• Maximum Value of eff. Bed Shear Stress
• Minimum Value of eff. Bed Shear Stress
• Mean Value of eff. Bed Shear Stress
• Maximum Variation of eff. Bed Shear Stress
• Maximum Increase of eff. Bed Shear Stress
• Maximum Decrease of eff. Bed Shear Stress
• Standard Deviation of eff. Bed Shear Stress
• Variance of eff. Bed Shear Stress
• Duration of High eff. Bed Shear Stress
• Duration of Low eff. Bed Shear Stress

Input-Files

1. general input data (filetype lzksf.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 lzksf.sdr)
3. (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, temperature or eff. bed shear stress 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 increase or decrease of salinity takes into account an averaging process of the respective salinities for a user-defined time intervall (typically 30 minutes). Drying and wetting of computational nodes is correctly taken into account.
