| Sumario: | <p>Previous studies on tidal flood mapping are mostly
through continental- and/or global-scale approaches. Moreover, the few works
on local-scale perception are concentrated in Europe, Asia, and North
America. Here, we present a case study approaching a tidal flood risk
mapping application in the face of climate change scenarios in a region with
a strong environmental and social appeal. The study site is an estuarine cut
in the Brazilian semi-arid region, covering part of two state conservation
units, which has been suffering severe consequences from tidal flooding in
recent years. In this case study, we used high-geodetic-precision data
(lidar DEM), together with robust tidal return period statistics and data
from current sea level rise scenarios. We found that approximately 327.60
km<span class="inline-formula"><sup>2</sup></span> of the estuary is under tidal flood risk and in need of
mitigation measures. This case study can serve as a basis for future
management actions, as well as a model for applying risk mapping in other
coastal areas.</p> |
