Use of the program Velgrid and AutoDEPOMOD(v3)

AutoDEPOMODv3 (denoted ADv3) can run with spatially varying velocity grids. Velgrid is used to (i) make interpolations from hydrodynamic model grids and (ii) create a special INI file that ADv3 can use.

Getting started - step by step

1. Decide on the area of interest, and set up the bathymetry grid and cages in ADv3 as usual. Information on the size of the grid used in the area of interest is required by Velgrid. (details of setting up ADv3).
2. Take current velocity u and v predictions from a hydrodynamic model which overlaps the area of interest - a linear grid is required as well as predictions for every time step in the model run (usually 360 hours) and surface, mid and near-bed current.
3. Set up and run the Velgrid interpolation dialog to create ADv3 compatible velocity grids. See Diagram B - Use of Velgrid.
4. Create a Velgrid INI file. This notifies ADv3 how to use the velocity grids. It can also notify ADv3 that there are no velocity grids, in which case, velocity data should be specified as with AD version 2 - see Diagram C - Creation of Velgrid INI file
5. Run ADv3.
