| description | <p>Over the past decade, several coastal communities in
southeast Florida have experienced a significant increase in flooding
frequency, which has caused significant disturbance to property, commerce,
and overall quality of life. The increased flooding frequency reflects the
contribution of global, regional, and local processes that affect elevation
difference between coastal communities and rising sea level. In a recent
project, funded by the state of Florida, we monitor coastal subsidence in
southeast Florida using GPS and InSAR observations, in order to evaluate the
contribution of local subsidence to the increased coastal flooding hazard.
Preliminary results reveal that subsidence occurs in localized patches
(< 0.02 km<span class="inline-formula"><sup>2</sup>)</span> with magnitude of up to 3 mm yr<span class="inline-formula"><sup>−1</sup></span>, in urban areas
built on reclaimed marshland. These results suggest that contribution of
local land subsidence affect only small areas along the southeast Florida
coast, but in those areas coastal flooding hazard is significantly higher
compared to non-subsiding areas.</p> |
