[RWG] WEBINAR: A coastal hazard assessment with high-resolution data: A Pacific Island Case study (Dec. 5, 3pm ET)

[De Angelis, Patricia]

This webinar may be of interest to restoration as coastal resiliency
assessments have noted the importance of restoring native vegetation.

What will you learn?
Low-lying island environments are particularly vulnerable to impacts from
coastal hazards, including inundation (coastal flooding), whether the
increased water levels are from episodic events (storm surge, wave run-up,
king tides) or from chronic conditions (long term sea-level rise).
Elevation is the primary geophysical variable that determines exposure to
inundation in coastal settings.  Accordingly, coastal elevation data are a
critical input for assessments of inundation exposure.  High-resolution,
high accuracy data from multiple remote sensing sources (unmanned aerial
systems, sonar, lidar, satellite imagery) are used to construct seamless
elevation models across the land-water interface, and these models are used
in coastal assessments. This much-needed information will provide
government authorities and local community groups with an improved
understanding of the types of actions needed to prepare for future
inundation and an estimated timeline for when these actions would best be
implemented.

A quantitative analysis of inundation exposure was conducted for Majuro
Atoll in the central Pacific nation of Republic of the Marshall Islands.
The resulting mapping products delineate areas subject to marine inundation
and other low-lying lands at different inundation levels, and they
demonstrate the substantial value of high-resolution, high-accuracy data
for assessing inundation exposure and the enhanced information from
accounting for vertical uncertainty.  The integrated coastal elevation
models are developed as a component of the USGS Coastal National Elevation
Database (CoNED) project, and additional application examples along the
U.S. coast are shown. The results of this project will support assessments
of how future inundation events could impact ecosystems, infrastructure,
the freshwater supply, and agroforestry on Majuro Atoll.
