Fort.141: Time Varying Bathymetry Input File

The ADCIRC Time Varying Bathymetry Input File (fort.141) is used by ADCIRC whenever the NDDT value in the fort.14 is nonzero. There are two variations of this file, depending on the value of NDDT.

Full Domain Bathymetry Change

If NDDT is +/-1, then each bathymetry dataset in the file covers the full domain, and the file format is as follows:

for i=1 to numDataSets
    for j=1 to NP
        j, depth(j)
    end j loop
end i loop

where: - NP is the number of nodes in the horizontal mesh - j is the node number - depth(j) has the same meaning as DP in the mesh file (fort.14)

Limited Area Bathymetry Change

If NDDT is +/-2, then each dataset in the fort.141 file covers only part of the domain, and the file format is as follows:

for i=1 to numDataSets
    "#"
    for j=1 to areaNodes
        j, depth(j)
    end j loop
end i loop

Notes

• This file is only required when NDDT is nonzero

• For NDDT=+/-1: - Each dataset must cover all nodes in the domain - The number of records per dataset is fixed (equal to NP)

• For NDDT=+/-2: - Each dataset can cover a different subset of nodes - The separation between datasets is achieved by placing a hash mark (“#”) in the second column of a line - This allows for simulations where the number of nodes that change their bathymetry varies over time

• The depth values have the same meaning as the DP values in the mesh file (fort.14)
