Sediment transport modifications induced by submerged artificial reef systems: a case study for the Gulf of Venice

Abstract: The shallow, gently sloping, sandy-silty seabed of the Venetian coast (Italy) is studded by a number of outcropping rocky systems of different size encouraging the development of peculiar zoobenthic biocenoses with considerably higher biodiversity indexes compared to neighbouring areas. In order to protect and enhance the growth of settling communities, artificial monolithic reefs were deployed close to the most important formations, providing further nesting sites and mechanical hindrance to illegal trawl fis… Show more

“…Conversely, the COD, IN, and IP were lower than in the control region. In addition, the deployment of ARs can alter the regional ow eld [20] and promote the release of bottom nutrients into the pelagic layer, which is conducive to phytoplankton growth and reproduction [21,22] . This nding was further con rmed in this study.…”

“…In order to explore how the uncertainty on the evolution of the environmental variables can affect the results of the present work, a sensitivity analysis was performed by running a set of additional HSM simulations in the future scenario, in which the projected values of each environmental variable were singularly increased and decreased by an estimate of the related uncertainty. The amount of this perturbation was defined based on existing large-scale modelling projections or, if unavailable, from information on basin-scale variability in present conditions (Bonaldo et al, 2014;Soto-Navarro et al, 2020;and Reale et al, 2022). For light radiation, in particular, the variation for the sensitivity analysis was chosen as the standard deviation of the present values restricted to a bathymetric range between -18 and -40m.…”

“…Astronomical tides provide the main hydrodynamic forces for transporting materials (e.g., sediment or salinity) upstream in tide‐dominated estuaries, which have long been subject to intensive human interventions (Chant, Sommerfield, & Talke, 2018). Temporal–spatial tidal forcing affects not only the transport of sediments, nutrients, and contaminants (Falcão, Santos, Drago, Serpa, & Monteiro, 2009; Bonaldo et al, 2014) in estuaries but also salt intrusion and storm surge propagation (Zhang, Savenije, Wu, Kong, & Zhu, 2011; Zhang, Savenije, Chen, & Mao, 2012; Li, Zhu, Wu, & Guo, 2014). In recent decades, intensive human activities (e.g., dredging for navigation, sand excavation, and land reclamation) have dramatically changed the morphology of many estuaries and, have caused the erosion of estuarine saltmarshes (Bendoni et al, 2016; Francalanci, Bendoni, Rinaldi, & Solari, 2013; Tommasini, Carniello, Ghinassi, Roner, & D'Alpaos, 2019) and altered the tidal regimes and hydrodynamics (Zhang et al, 2017; Mei et al, 2018; Wu et al, 2018; Zhang et al, 2018; Finotello Canestrelli, Carniello, Ghinassi, & D'Alpaos, 2019).…”
