HAZUS: HAZUS Depth-Damage Curves

In essatech/MNAI.CPBT: Municipal Natural Assets Initiative - Coastal Protection Benefit Toolbox

HAZUS Depth-Damage Curves

Description

HAZUS depth-damage reference curves showing the relative damage that a structure receives based on the flood depth from a given storm event. Damage estimates range from 0 to 1 and are referenced to the current structure value (replacement cost). A value of 0 indicates no damage whereas a value of 1 indicates complete damage (equivalent to the replacement cost of the structure). Note that curves apply to structures only (not content) and may represent an oversimplification for individual units. Depth-damage curves in this dataset are limited to short, salt-water exposure from the USACE - New Orleans curve database.

Usage

data(HAZUS)

Format

A data frame with 1500 rows and 6 variables:

DDID

Depth-damage curve ID.

Description

Structure types applicable to depth-damage curve.

damage

Portional damage (0-1) to the structure from flood water relative to the total structure value (replacement cost).

depth_m

Floodwater depth in meters for a given structure

Floors

Number of floors for a given structure.
