CMS-Wave structure files contain a line defining the number of cells that should be treated as structures in the model simulation, and then a list of these cells with special features assigned to them. These are specified in the SMS interface by selecting the cell and assigning cell attributes (CMS-Wave menu or right click on selected cell). These cells can represent:
- a floating breakwater
- a bottom mound breakwater
- a beach segment and the land adjacent to it
- jetties or seawalls
- underwater features such as reefs or submerged structures
A trench, submerged mound or structure can be added to the bed as features without modifying the input depth file. Each feature cell is described by four parameters in a line in the structure file. A sample file and table of the parameters is defined below.
File Format
number of structure cells one row for each structure cell (each row includes the I and J indices of a selected output cell, the structure type and the modifier value
Sample File
4 /* there are 5 structure cells in this sample file */ 10 15 1 3 /* cell (10,15) will be modified to have a depth of 3 meters */ 23 41 2 0.5 /* model will calculate runup and overwash at cell (23,41). It will be assigned an elevation 0f 0.5 meters above sea level */ 15 7 3 1.5 /* model will treat cell (15,7) as a floating breakwater with a draft of 1.5 meters to calculate transmission of waves under the structure */ 16 22 4 3 /* model will treat cell (16,22) as a breakwater/seawall/mound with an elevation of 3 meters above sealevel */
Parameter definitions
| kstruc | Description | Modifier value (cstruc) |
|---|---|---|
| 1 | add alternative depth without modifying input depth file | specify the new structure depth (assumed land if no depth specified) |
| 2 | for calculation of wave runup and overwash on beach face or structure and adjacent land | specify the elevation above mean water level for the cell. Input depth used in no value specified. Has no impact if elevation < 0) |
| 3 | for calculation of transmitted wave under a floating breakwater | specify the floating breakwater draft (skipped if not provided or value is < 0.05 m) |
| 4 | for a vertical wall breakwater | specify breakwater/structure elevation (input depth value used in not provided; immersed if value < 0.0) |
| 5 | for a composite or rubble-mound breakwater |
