“…In this work, we investigate in detail the seafloor morphology of a tidal inlet and the impact induced by recent human modifications. Inlets play a key role in the evolution of coastal barrier systems (Kjerfve, ; Tambroni and Seminara, ; De Swart and Zimmermann, ; Reddy et al ., ) given that they: (i) control hydrodynamics, i.e. the rate of water exchange which influences the chemical–physical properties of the lagoon; (ii) are responsible for the sediment transport from the lagoon to the open sea and vice versa; (iii) affect the morphodynamics of the adjacent coast; (iv) allow the migration of different species at different life stages.…”

Adopting a multidisciplinary approach, we mapped with unprecedented detail the seafloor morphology, sediment distribution and benthic habitats of a tidal inlet in the Venice Lagoon, Italy, which has been greatly impacted by human activity. Thanks to very high-resolution multibeam data, we identified ebb and flood-tidal deltas, a tidal point bar, active dune fields, pools and scour holes.The seafloor substrate of the inlet was investigated by integrating automatically classified multibeam backscatter data with sediment samples and underwater seafloor images. The sediment composition comprises four textural classes with 75% overall thematic accuracy. The particle size distribution of each morphological feature was assessed distinguishing, in particular, sediments over crests and troughs of small-dune fields with wavelengths and heights of less than 4 m and 0.2 m, respectively.Adopting state-of-the-art benthic habitat mapping procedures, we found seven distinctive benthic habitats that reflect spatial variability in hydrodynamics and sediment transport pathways. The dominant classes were Sand with sparse shell detritus (46%) and Bare sand (32%). The rip-rap revetment used for the inlet jetties and for the hard structures, built in the inlet channel to protect Venice from flooding, created a new habitat that covers 5.5% of the study area. This study shows how combining geomorphological and ecological analyses is crucial for the monitoring and management of tidal inlets and coastal infrastructures.

The morphological evolution of a lagoon tidal inlet over a medium-long period is a very important research topic since it can greatly affect both the hydrodynamic balance of the coastal environment and all the several human activities related to its proper functioning. The morphodynamic balance, which is the result mainly of the complex interaction of tidal currents and wind waves, can also be deeply influenced by the presence of maritime structures that are required for sea defence. This is the case of the Lignano inlet, which has undergone a progressive narrowing during last decades. In order to investigate the causes of this process and to evaluate possible solutions for the consequent filling of the port access canal, a morphodynamic-spectral coupled model has been applied to this context. Results are presented and discussed confirming that the numerical modelling can be used as a useful engineering tool for the correct management and the integrated planning of coastal zones.
