SYSTEMS AND METHODS FOR FLOOD RISK ASSESSMENT
First Claim
1. A computer-implemented method for predicting a flood elevation for a flood frequency for a property point, comprising:
- calculating with a processor at least two points of flood frequency versus flood elevation for the property point using a flood map;
defining a relationship between flood frequency and flood elevation for the property point using the at least two points; and
predicting with the processor at least one flood elevation at a flood frequency different from the flood frequency of one of the at least two points for the property point using the relationship;
wherein the flood map comprises a map of flood zones, defined by flood boundaries, and a plurality of pre-existing flood elevation lines.

Abstract
In various embodiments, points from flood maps (e.g., geospatial flood risk zoning maps) may be used in generating a flood frequency versus flood elevation curve for reducing the uncertainty in the flood risk assessment. In some embodiments, geospatial flood elevation lines for flood elevation lines at different flood frequency levels may be defined based on elevation datasets where there are inconsistencies between the elevation datasets and flood maps that were generated. The flood frequency versus flood loss curve may be derived based on the computed flood frequency versus flood elevation curve, digital elevation datasets, and collected damage curve. In some embodiments, the flood risk rating may also be derived and a flood risk assessment report may be generated.
