ABSTRACT
Hydro-geomorphologic setting of coastal areas
is the result of complex interactions between
marine and continental processes. Lowland
morphologies make coastlands the zones at
highest hydrogeological risk because of flooding,
land subsidence, and saltwater contamination (e.g.,
Pousa et al. 2007). As many studies have predicted
a significant increase of eustacy, sea level rise
(SLR) is the most relevant problem affecting coastal
lowlands.
The wetland of the Samborombon Bay (Argentina)
is a Ramsar natural reserve affected to periodic
floods due to rainfall, runoff, tidal fluctuations, and
storm surges. In this work, we show preliminary
results of a project aimed at understanding the
effect of expected SLR scenarios on the hydromorphologic
setting of the Samborombon Bay.
In particular, the outcomes of the first step of the
research, i.e., the remote sensing analysis, are
illustrated.
