|shortdescription=
The program TDKVF is a postprocessor for different numerical models (e.g. TRIM-2D, TRIM-3D, TELEMAC-2D, UNTRIM, UnTRIM2007 etc.). TDKVF automatically computes the tidal characteristic numbers of current for a given set of results (universal direct access data format).
Data analyses can only be performed for static (constant in time) bathymetry. Bathymetry data must be either present in the grid file or given as alternative bathymetry in the data file containing also the computational results for water level.
The results of TDKVF analyses may be visualized/displayed with the graphical postprocessors HVIEW2D (for 2D/3D-data) or LQ2PRO (for profile-data).

Within the period of data analysis the following tidal characteristic numbers of current are calculated (some numbers are optionally calculated):

- Flood Current
- Maximum Flood Current Velocity
- [[Mean Flood Current Velocity
- Flood Volume
- Flood Current Duration
- Slack Water Time of Flood Current
- Slack Water Duration around Slack Water Time of Flood Current
- Slack Water Dislocation of Flood Current
- Differences of Time of Maximum Flood Current between Different Locations
- Flood Path

- Tidal Cycle
- Residual Current
- Eulerian Residual Path
- Residual Flow
- Tide Volume
- Ratio Flood Current Duration : Ebb Current Duration
- Ratio Max. Flood Current Velocity : Max. Ebb Current Velocity
- Ratio Mean Flood Current Velocity : Mean Ebb Current Velocity
- Ratio Flood Path : Ebb Path
- Ratio Flood Volume : Ebb Volume

For each characteristic number of current the following values are being calculated for the period of data analysis:

- Characteristic value for each tide within the period of data analysis
- Mean value for the period of data analysis
- Maximum value for the period of data analysis
- Minimum value for the period of data analysis

|methodology= At first some extreme events (HW and LW) for the water level are determined for a network of reference locations for each tidal cycle. This ensures the phase-correct ordering of the events for all nodes of the computational grid respectively profile-topography. This first step is followed by a calculation of the times of slack water (ebb slack and flood slack). Thereafter the tidal characteristic numbers for the current are calculated at all nodal points, using the formerly calculated results at the reference locations. To obtain a more precise calculation of the times and values for all tidal characteristic numbers of water level a spline interpolation is used to interpolate between equidistant time series data at each nodal point. Drying and wetting of tidal flats is taken into account by the algorithm. |preprocessor=DIDARENAME, DIDASPLIT, ZEITR |postprocessor=ABDF, DIDARENAME, DIDASPLIT, GVIEW2D, HVIEW2D, LQ2PRO, VTDK, VVIEW2D, XTRDATA |language=Fortran90 |add_software=- |contact_original=G.
