Resumen:
Climate
variability
is
one
of
the
most
important
topics
to
understand
the
spatial
dynamics
of
water
bodies.
This
variability
may
cause
economical
impacts
on
tourism,
decrease
in
fishing
and
damages
due
to
the
floods.
In
La
Picasa
shallow
lake,
located
in
Santa
Fe
Province,
Argentina
extreme
events
are
challenging
public
institutions
to
focus
on
developing
adequate
structures
mainly
to
mitigate
the
occurrence
of
floods.
In
the
last
decade,
hydrological
events
affected
the
local
population
and
their
activities.
We
present
the
preliminary
results
of
the
analysis
of
the
effects
of
climate
variability
on
La
Picasa
shallow
lake.
Data
from
a
meteorological
station
located
northeast
of
the
lake
was
processed.
The
study
period
is
1960-‐2010.
Decadal,
inter-‐
annual
and
inter-‐seasonal
time
scales
were
applied
to
analyze
this
information.
Satellite
images
were
processed
to
characterize
the
spatial
dynamics.
Results
showed
that
wet
extreme
events
were
more
intensive
than
dry
ones.
The
positive
anomalies
of
precipitation
ranged
between
500
to
800
mm
per
year,
while
the
negative
ones
between
300
to
350mm
per
year.
During
the
study
period,
the
mean
temperature
increased
0.5
ºC.
Thermal
anomalies
ranged
between
+/-‐
1ºC.
In
addition,
the
relative
humidity
increased
5
%
and
the
variations
of
wind
intensity
were
significant
along
the
period.
These
analysis
results
could
be
useful
to
public
organisms
that
are
working
on
lake
management.
