The water flow in two inlets of the Marano-Grado Lagoon, the second biggest lagoon in Italy, has been monitored during 2010/2011 with Acoustic Doppler Current Profilers. The flow is highly polarized along the channel axis (99% of the variance). A barotropic regime prevails along the water column; therefore the vertical average is representative of the total variability. All the major tidal constituents of the Adriatic are present in the flow, accounting for more than 90% of the total energy. Seiches account for about 80% of the non-tidal energy. Low-frequency variability is related predominantly to the non-linear wind forcing, with Bora (from NE) exerting the highest influence.

Abstract
The water flow in two inlets of the Marano-Grado Lagoon, the second biggest lagoon in Italy, has been monitored during 2010/2011 with Acoustic Doppler Current Profilers. The flow is highly polarized along the channel axis (99% of the variance). A barotropic regime prevails along the water column; therefore the vertical average is representative of the total variability. All the major tidal constituents of the Adriatic are present in the flow, accounting for more than 90% of the total energy. Seiches account for about 80% of the non-tidal energy. Low-frequency variability is related predominantly to the non-linear wind forcing, with Bora (from NE) exerting the highest influence.Pubblicazioni consigliate
