Abstract We analyse the impact of ship traffic in vicinity navigation channels a wide shallow waterbody. The crucial hydrodynamic driver this situation is depression (Bernoulli) wake that may be transferred into long-living solitary wave over shoals. analysis considers Venice Lagoon using new large dataset approximately 600 measured events associated to specific ships whose data are provided by AIS system. Since development modern industrial port and opening Malamocco–Marghera channel late...
Abstract Saltwater intrusion (SWI) in deltas, estuaries, and other coastal areas represents a pressing problem affecting the sustainability of freshwater resources. Observations numerical experiments are used to investigate SWI surface waters Italian's largest river delta (the Po Delta) under low discharge conditions. The model successfully reproduced observed salinity variations along main branches lagoons investigated fresh saltwater dynamics during entire summer 2017. is explore...
The oceanographic forecast capability in coastal seas is often limited by the capacity of numerical models correctly reproducing complex morphology coastline and exchange processes between shelf open seas. In marginal Adriatic Sea this task uppermost importance due to presence several water bodies rivers. We present here a new operational system, called Tiresias, based on unstructured grid model SHYFEM representing whole together with lagoons Marano-Grado, Venice Po Delta. novelty system...
An investigation based on in-situ surveys combined with remote sensing and GIS analysis revealed fast shoreline retreat the side of a major waterway, Malamocco Marghera Channel, in Lagoon Venice, Italy. Monthly long-term regression rates caused by ship wakes reclaimed industrial area were considered. The short-term analysis, field carried out between April 2014 January 2015, that speed was insignificantly dependent distance from navigation channel, but not constant through time. Periods high...
Abstract Tidal channels are crucial for the functioning of wetlands, though their morphological properties, which relevant seafloor habitats and flow, have been understudied so far. Here, we release a dataset composed Digital Terrain Models (DTMs) extracted from total 2,500 linear kilometres high-resolution multibeam echosounder (MBES) data collected in 2013 covering entire network tidal inlets Venice Lagoon, Italy. The comprises also backscatter (BS) data, reflect acoustic properties...
Abstract. A multiscale sampling experiment was carried out in the Gulf of Taranto (eastern Mediterranean) providing first synoptic evidence large-scale circulation structure and associated mesoscale variability. The mapping geostrophic showed presence an anticyclonic gyre occupying central open ocean area Taranto. On periphery upwelling is evident where surface waters are colder saltier than at center gyre. Over a 1-week period, rim current undergoes large changes which interpreted as...
Abstract. The present work describes an operational strategy for the development of a multiscale modeling system, based on multiple-nesting approach and open-source numerical models. was applied validated Gulf Taranto in southern Italy, scaling large-scale oceanographic model results to high-resolution coupled wave–3-D hydrodynamics simulations area Mar Grande Sea. spatial temporal were performed using TELEMAC suite, forced by wind data from COSMO-ME database, boundary wave spectra RON buoy...
Abstract Adopting a multidisciplinary approach, we mapped with unprecedented detail the seafloor morphology, sediment distribution and benthic habitats of tidal inlet in Venice Lagoon, Italy, which has been greatly impacted by human activity. Thanks to very high‐resolution multibeam data, identified ebb flood‐tidal deltas, point bar, active dune fields, pools scour holes. The substrate was investigated integrating automatically classified backscatter data samples underwater images....

An observation system integrating satellite images, in situ water parameters and hydrodynamic measurements was implemented a tidal inlet of the Venice Lagoon (Northern Adriatic Sea, Italy). The experimental infrastructure developed to autonomously investigate suspended sediment dynamics two channels Lido relation longshore currents littoral zone circulation along lagoon channel network. It provided time series turbidity at surface, flow acoustic backscatter, which converted into vertical...
Environmental monitoring and protection of our oceans has become an absolute priority recognized as well by the United Nations its UN Ocean Decade. Marine robotic systems can play a fundamental role in this field due to their lower cost autonomous behavior when compared research vessels. This article details first use-case scenario defined within INNOVAMARE project where Autonomous Surface Vessel (ASV) Smart Buoy cooperate real fragile environment Venice Lagoon. Preliminary results show...
Abstract The paper shows for the first time observational evidence of basin‐wide gyre reversal in Gulf Taranto (north‐western Ionian Sea eastern Mediterranean Sea) by means two specifically designed situ oceanographic campaigns (based on CTD and ADCP measurements). analysis data a change circulation from anticyclonic October 2014 to cyclonic June–July 2016. Furthermore, long‐term (1993–2018) using gridded satellite altimetry that gyres are more frequent than gyres. latter occur only 2 3...

The sediment load from the drainage basin may play a key role in sustaining fragile tidal and subtidal habitats of Venice Lagoon, which underwent significant erosional losses recent decades. Freshwater discharge suspended transport were studied two estuarine sections main tributary lagoon, Dese River, employing acoustic instruments analyzing accumulation estuary through bathymetric measurements. results for 2021 are discussed terms discharge, rainfall–runoff relationships, load, impact...
