Significance of the File

coupling files for DelWAQ

File-Contents (in Catchwords)

• ASCII files
  • Filetype .hyd

    General input data for DelWAQ.

    Example WAQ.hyd (PDF).

  • Filetype .dat

    Description of the open boundary sections where water is exchanged.

    Example WAQ.dat (PDF).

  • Filetype .src

    Description of sources and sinks.

    Example WAQ.src (PDF).

• Binray files (STREAM, SEQUENTIAL, little endian)
  • Filetype .poi

    All (control) volumes are numbered from 1 to NOSEQ.

    All boundary volumes are numbered from -1 to -NOBND.

    For all NOQ exchange faces (exchanges) the FROM-TO volumes must be specified.

    Four (INTEGER) numbers each: FROM, TO, FROM-1 and TO+1.

    Postive flow is directed FROM - TO.

    Horizontal exchange faces first, vertical exchange faces second.

    In case of 3D layerwise from top to bottom.

  • Filetype .flo

    Fluxes for all NOQ exchange faces (observe FROM - TO). Fluxes are mean flows within the averaging period.

    For each record:

    1. (INTEGER) time in seconds since reference date.
    2. (REAL SINGLE) mean flow in [m**3/s] for the averaging period.

    Remark: At the end of the last averaging interval also a record has to be written. Solely the time stamp is used. Data are neglected.

  • Filetype .vol

    Water volumes in [m**3] for all NOSEQ control volumes.

    Volume must be >= 0.0.

    For each record:

    1. (INTEGER) time in seconds since reference date.
    2. (REAL SINGLE) water volumes in [m**3].

    Remark: At the end of the last averaging interval also a record has to be written. But now time as well as data are of relevance.

  • Filetype .are

    Mean flow area in [m**2] for all NOQ exchanges.

    Flow area must always be > 0.0.

    For each record:

    1. (INTEGER) time in seconds since reference date.
    2. (REAL SINGLE) flow area in [m**2].

    Remark: Identical with .flo.

  • Filetype .srf

    Representative horizontal area in [m**2] for all NOSEQ control volumes.

    Relevant for the determination of average depth, impact of sedimentation and deposition, solar radiation etc.

    For each record:

    1. (INTEGER) time in seconds since reference date.
    2. (REAL SINGLE) horizontal area in [m**2].

    Remark: Identical with .flo.

  • Filetype .len

    Typical distance in [m] to adjacent control volumes for all NOQ exchanges.

    A FROM as well as a TO distance must be specified.

    For the first record:

    1. (INTEGER) time in seconds since reference date.
    2. (REAL SINGLE) FROM and TO distances in [m].

    Remark: no change in time, write only once.

• cf-netcdf.nc
  • Filetype .nc

    Grid as well as volume aggregation table.

    For further informations see NetCDF DelWAQ data.
