Short Description of Functionality

Program DATACONVERT is used to convert computational results and data:

• mode 1: conversion of computational results from the integrated modelling system Delft3D into BAW-specific data formats, with
  
  • conversion of a Delft3D computational grid into UnTRIM grid format,
  • conversion of two-dimensional (depth averaged) Delft3D computational results into BDF data format (2D),
  • conversion and depth averaging of three-dimensional Delft3D computational results into BDF data format (2D), and
  • conversion of three-dimensional Delft3D computational results (sigma-coordinates) into BDF data format (3D, z-layers).
    

Dynamic model bathymetry (morphodynamics) is supported for 2D as well as 3D computational results. If Delft3D model results have been produced for a domain decomposition run, the converted results are written to different domain-specific data files and are not yet combined into one single file.

A conversion into the subsequent physical output quantities is currently possible:

1. water level,
2. current velocity,
3. salinity,
4. temperature,
5. bathymetry (static),
6. transient bathymetric depth,
7. vertical erosion,
8. suspended load (icode=7),
9. new: (mass) bed load transport rate (icode=621), converted from a volume transport rate,
10. new: (mass) suspended load transport rate (icode=622), converted from a volume transport rate and
11. new: bottom shear stress

• mode 2: conversion of (DWD) NetCDF data files into BAW-specific data formats, with
  • generation of a grid from data points defined in the NetCDF data file, and
  • conversion of NetCDF data into BAWs BDF file format.
    
• mode 3: merge contents of several (DWD) NetCDF data files into a single NetCDF data file, with
  • transfer of meta data as well as data for identical dates into a single NetCDF data file.
• mode 4: conversion of BDF data into cf-netcdf.nc data, for
  • synoptic data at multiple locations.
  • synoptic data for triangular grid.
  • synoptic (morphological) data for triangular grid.
  • synoptic data for unstructured grid.
  • synoptic data for multiple profiles.
• mode 6: conversion of meteorological data into Delft3D format METEO_DLFT.
• mode 7: conversion of timeseries and meta information in BOEWRT format into cf-netcdf.nc data according to NODC's feature type template for timeSeries. Creation of optional status flag variable for description of data quality is supported.
• mode 8: conversion of CF SGRID NetCDF into CF UGRID NetCDF (see cf-netcdf.nc).

Input-Files

Methodology

The original computational grid is in case converted using methods from software package H_GRID or L_GRID. Interpolation of computational results is performed using methods from the H_IP package. Read and Write of computational data is carried through essentially using methods from software package IO_DATASET and in mode 6 also using IO_DELFT.
