Fort.77: Time-varying Weir Output

This file contains time-varying weir elevation data when time-varying weirs are activated and output is requested in ADCIRC. The file records changes in elevation from the original elevations specified in the Grid and Boundary Information File. When written in sparse format, the data is recorded only for weir nodes, with node numbers referenced to the global node numbering system.

File Structure

The basic structure is shown below:

RUNDES, RUNID, AGRID

NDSETSE, NP, DTDP * NSPOOL_TVW, NSPOOL_TVW, IRTYPE

TIME, IT

for k=1, NP
    k, TVW(k)
end k loop

Notes

  • Only elevation changes relative to the original fort.14 elevations are recorded

  • When using sparse format, only weir nodes are included in the output

  • Node numbers (k) reference the global node numbering system

  • The output frequency is controlled by NSPOOL_TVW parameter

  • TVW(k) represents the change in elevation at node k from the original fort.14 elevation
