A depth-damage function is a mathematical relationship between the depth of floodwater above or below the first floor of a building and the amount of damage that can be attributed to that water. The depth-damage relationship is the most important tool in the cost-benefit analysis of flood damage reduction projects. This reports presents a comprehensive catalog of residentail depth-damage functions used by Corps of Engineers district offices. These damage functions include those computed from National data of flood damage records as well as those originally computed on a project-specific basis and now in general use. This catalog should help analysts who perform flood damage estimates to carefully consider existing local damage functions, and has the functions compare with depth-damage functions used by other Corps of Engineers districts.
