CMS-Wave Depth File

Constant X and Y spacing

Depth file (*.dep). A sample depth file with constant X and Y spacing is shown below:

3 6 100.00 200.00
9.93125 9.79375 9.65625 7.51875 3.38125 1.24375
8.55625 7.41875 5.28125 3.14375 1.00625 -0.86875
8.18125 7.04375 4.90625 2.76875 -0.63125 -1.49375

The first line contains:

• The number of rows (3)
• The number of columns (6)
• The cell size in the x direction (100.00 m)
• The cell size in the y direction (200.00 m)

Depth values are then specified for each cell in the row-to-row order (from top row to bottom row in the model domain).

Variable X and Y spacing

If however, you have a variably spaced grid, a sample file shown below.

The first line contains:

• The number of rows (147)
• The number of columns (181)
• The largest size of either dx or dy (1492.249106 m)
• Flag that tells CMS-Wave that cell sizes are variable (999.000000)

1. Depth values are then specified for each cell in the row-to-row order (from top

row to bottom row in the model domain).

1. DX values are specified for each cell in the x-direction (147 values)
2. DY values are specified for each cell in the y-direction (181 values)
