A depth-percent damage relationship (i.e., curve) defines the percent damage caused to a structure, a structure's contents, and any vehicles stored at a structure at incremental depths. As depth increases, percent damage also increases. Depth-percent damage relationships are defined in HEC-FIA within the Structure Occupancy Type dialog. An example depth-percent damage relationship is shown in the table below. For depths between ordinates, the percent damage is linearly interpolated.
Example Depth-Percent Damage Relationship
Depth (feet) | Percent Damage |
0.00 | 0.00 |
1.00 | 32.00 |
2.00 | 38.70 |
3.00 | 45.50 |
4.00 | 52.20 |
5.00 | 58.60 |
6.00 | 64.50 |
7.00 | 69.80 |
8.00 | 74.20 |
9.00 | 77.70 |
