Long-term changes in the kinematics of inlets of the Venetian Lagoon (NE Italy)

Abstract

Long-term variations of the water flow through three Venice lagoon inlets are analysed seeking for the possible impact of structures under construction for the mobile gates for defending Venice against flooding. Time-series of monthly mean How and standard deviations show long-term variations, mainly on the seasonal time-scale. An important increase in the water flow variance due to an increase in amplitudes of major tidal constituents in the Chioggia inlet can probably be explained as a consequence of the structures constructed recently that narrowed the channel.
