Risk of Loss Analysis and Mapping of Coastal Wetland Habitat


Reference #:  00699

Invention Description:

This technology is a novel method of computing the risk of losing coastal wetlands to submergence (habitat loss) due to sea-level rise and erosion.  This novel method analyzes high density and spatially extensive elevation data that can predict a risk of loss estimate without prior knowledge of the vertical limits of a wetland. The statistical results can be mapped and reveal locations of marsh habitats that are vulnerable to sea level rise and erosion, as well as the distribution of greatest storm buffering capacity.


Advantages and Benefits:

The method allows for prediction and calculation of risk of loss of wetlands due to sea level rise and erosion without any prior knowledge of the history of the property.  This saves both time and money for all parties involved when deciding to develop or insure a property on or adjacent to a wetland. 


Potential Applications:

Data extracted from this method will assist property owners, zoning boards, and the insurance industry when assessing the risk and hazards associated with coastal development.  Furthermore, it can assist resource managers in assessing the stability of habitats that are critical for biological resources.


Development/Demonstration / Validation:

Simulations of hypothetical wetland habitats have been conducted.  Data collected using the above method showed that marshes located high in the tidal frame have the lowest risk, while marshes located low in the tidal frame have the highest risk of loss.
