Flood Risk Scoring via Elevation and Proximity Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flood risk assessment methods are inadequate in providing comprehensive and accurate flood risk scores for properties, as they primarily rely on binary classifications within FEMA Special Flood Hazard Areas, failing to account for various flood risk characteristics such as elevation differences, proximity to flood sources, and historical weather patterns.
Innovation Solution
A system that determines a flood risk score for a property by evaluating multiple flood risk characteristics, including elevation differences, proximity to flood zones, and historical weather data, using geospatial analysis and hydrological modeling to provide a comprehensive flood risk assessment report.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional binary classification (inside/outside SFHA) is used for flood risk assessment, then the assessment process is simple and easy to implement, but the measurement precision of flood risk is insufficient
Solution Approach 1:
The patent segments the binary flood risk classification into multiple graded risk levels (e.g., low, moderate, high, very high risk) based on elevation zones relative to the flood source. Instead of simply classifying properties as inside or outside the SFHA, the system divides the floodplain into multiple elevation-based segments that provide a more nuanced assessment of flood risk, allowing for differentiated risk scoring while maintaining computational feasibility.
2Measurement precision
If multiple flood risk characteristics (elevation differences, proximity to flood sources, historical weather patterns) are evaluated, then the flood risk score precision is improved, but the device complexity increases
Solution Approach 1:
The patent extracts and prioritizes the most critical flood risk characteristics (elevation difference, proximity to flood source, historical weather patterns) from the complex set of possible risk factors. By focusing on these key extracted parameters rather than attempting to evaluate all possible characteristics, the system achieves improved measurement precision while avoiding the proportional increase in device complexity that would result from comprehensive multi-parameter evaluation.
Solution Approach 2:
The patent applies local quality by evaluating flood risk characteristics specific to each property's location and context. Rather than using a uniform assessment approach, the system tailors the evaluation to local conditions such as the specific elevation of the property, its precise distance to the flood source, and local historical weather patterns, thereby achieving high precision without requiring overly complex centralized processing.
3Reliability
If comprehensive flood risk characteristics are considered, then the reliability of flood risk assessment is improved, but the loss of information processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing key flood risk parameters such as elevation data, flood source locations, and historical weather patterns in accessible databases. This preliminary preparation of data allows the system to quickly retrieve and process relevant information when conducting flood risk assessments, thereby maintaining high reliability through comprehensive data consideration while minimizing the time loss associated with data collection and processing during the actual assessment.

AI summary
In various embodiments, a flood risk score may be determined for a property point that provides a comprehensive assessment of the property point's risk of flooding. Determining the flood risk score may include determining a flood risk characteristic for the property point and assigning a flood risk score that corresponds to the flood risk characteristic. In some embodiments, flood risk characteristics may include a difference in elevation between the elevation of the property point and an elevation of a calculated point (e.g., on a known flood risk zone boundary). Flood risk characteristics may also include a flood zone determination for the property point and/or proximity of the property point to a known flood risk zone boundary or a flood source. In some embodiments, flood risk scores may be provided on flood risk score reports.
