Resumen:
The short and medium-term coastal evolution
of Necochea Municipality, Buenos Aires province
(Argentina) was studied. The medium-term evolution study
was based on aerial photographs from 1967 and 1984, and
satellite images from 2004, using the dune or cliff toe as
coastline indicator. The short-term evolution was studied
from February 2006 to December 2009 by means of seasonal
beach profiles and sediment sampling. Results
showed that in the medium-term at Necochea, the coastline
has remained stable or has advanced. Whereas in the shortterm,
the analysis has evidenced incipient erosion processes.
On the other hand, at Queque´n the retreat of the
coastline and the negative sedimentary balances (medium
and short-term) are clearly indicating an accentuated erosion
process. The different degrees of coastal erosion are related in part to beach vulnerability to wave storms but
mainly to anthropogenic actions, which have affected the
beach sediment supply. These results evidence the necessity
to develop a coastal management programme.
