Figure 3: Numerical
modeling. (A) Water level and wind climate data utilized for the
numerical simulations. Data refer to the period 17 November 2005 – 17
December 2005. Water levels were measured at the “Punta della Salute”
tidal-gauge station, whereas wind data were retrieved from the
“Chioggia Diga Sud” anemometric station (see panel B). (B) An example
of the computational grid employed by the model, referred to the 2014
morphological configuration of the Venice Lagoon. (C,D)Distributions of
water levels (C) and wind climate (D) during the analyzed period are
compared to those observed over the period 2000-2019 (in grey).
All the simulations were carried out employing the same boundary
conditions, thus allowing for a comparison of the effects directly
related to morphological changes in the lagoon hydrodynamics.
Specifically, the model was forced using hourly water levels and both
wind velocities and directions measured from November
16th, 2005 to December 17th, 2005
(Figure 3 A). The selected 30-day-long study period is
representative of hydro-meteorological conditions experienced every year
by the Venice Lagoon between October 1st and January
30th, which is the period typically characterized by
the most significant storm-surge events.
