| Summary: | HAZUS flood depth-damage functions (DDFs) are commonly used outside of the HAZUS software. As far as I can tell, there is no persistent and archived repository that stores these DDFs. To fill this gap, I reached out to the HAZUS help desk and asked permission to upload the library of HAZUS DDFs to Zenodo. In addition to HAZUS DDFs, I also include a .csv file I created that uses the same format as the HAZUS DDF library to represent the DDFs from the 2015 North Atlantic Coast Comprehensive Study Physical Depth Damage Function Summary Report . There are 4 files uploaded to this repository. Below, I indicate the filenames, a brief description, and the source for the data. Source/procedure: https://github.com/cran/hazus/tree/master/data. Potentially longer term archiving available from https://rdrr.io/cran/hazus/. I downloaded haz_fl_occ.rda and haz_fl_dept.rda, opened them in R, and wrote out the corresponding files as csvs. haz_fl_dept.csv: This is a file with all DDFs in HAZUS (I believe this is version 5.1). You may be able to learn more about the metadata here: https://rdrr.io/cran/hazus/man/haz_fl_dept.html. The dataset includes occupancy codes (corresponds to one of our other files - haz_fl_occ) and other information that we need to estimate flood damages. The columns are feet relative to first-floor elevation of a structure. haz_fl_occ.csv: This is a file with all the occupancy codes for DDFs in HAZUS. You may be able to learn more about the metadata here: https://rdrr.io/cran/hazus/man/haz_fl_occ.html Source/procedure: https://www.fema.gov/sites/default/files/documents/fema_hazus-flood-model-technical-manual-5-1.pdf This link will almost certainly not work at some point in the future, but could probably be requested from FEMA by asking for the Hazus 5.1 Flood Model Technical Manual. Also, I have a pdf locally that I can send, but I am not sure if copyright protections prevent me from posting this myself online. I copy/pasted Table 5-2: Default Damage Functions for Estimation of Structure Damage in Riverine ...
