Coastal areas frequently face critical conditions due to the lack of adequate forms of land use planning, environmental management and inappropriate coastal risk management, sometimes leading to unexpected and un-desired environmental effects. Risk management also involves cultural aspects, including perception. However, the acknowledgement of risk...
Sandy beaches and the nearshore environment are dynamic coastal systems characterized by sediment mobilization driven by alternating stormy and mild wave conditions. However, this natural behavior of beaches can be altered by coastal defense structures. Repeated surveys carried out with autonomous surface vehicles (ASVs) may represent an interestin...
Coastal monitoring is strategic for the correct assessment of nearshore morphodynamics, to verify the effects of anthropogenic interventions for the purpose of coastal protection and for the rapid assessment of flooding vulnerability due to severe events. Remote sensing and field surveys are among the main approaches that have been developed to mee...
The coastal area at Riccione, in the southern Emilia-Romagna littoral region, is exposed to erosive processes, which are expected to be enhanced by climate change. The beach, mostly composed of fine sand, is maintained through various defense strategies, including frequent nourishment interventions for balancing the sediment deficit and other exper...
The Italian coastline stretches over about 8350 km, with 3600 km of beaches, representing a significant resource for the country. Natural processes and anthropic interventions keep threatening its morphology, moulding its shape and triggering soil erosion phenomena. Thus, many scholars have been focusing their work on investigating and monitoring s...
In fluid mechanics, fountains take place when a source fluid is driven by its own momentum into a surrounding ambient fluid and it is counterbalanced by buoyancy. These phenomena are largely encountered in nature and human activities. Despite the numerous studies on the subject, few experimental data are available about the internal structure of tu...
The need to remove deposited material from water basins is common and has been shared by many ports and channels since the earliest settlements along coasts and rivers. Dredging, the most widely used method to remove sediment deposits, is a reliable and wide-spread technology. Nevertheless, dredging is only able to restore the desired water depth b...
The use of video-monitoring techniques is significantly increased due to the diffusion of high-resolution cameras at relatively low-costs and they are largely used to estimate the shoreline evolution and wave run-up, as important coastal state indicators to be monitored and predicted for the assessment of flooding and erosion risks. In this work, w...
This work presents the MoonWEC, a new device for wave energy conversion. This new concept encompasses several working principles as the heaving point absorber, the oscillating water column and the overtopping. The development of the new WEC has been carried out through numerical modelling. Three main parts of the device have been simulated: a hollo...
In order to obtain a fair and reliable description of the wave amplitude and currents in harbors due to the tsunami generated by the 21 May 2003 Boumerdès earthquake (Algeria), a numerical investigation has been performed with a standard hydraulic numerical model combined with various source fault models. Seven different rupture models proposed in...
Marine coastal ecosystems are facing structural and functional changes due to the increasing human footprint worldwide, and the assessment of their long-term changes becomes particularly challenging. Measures of change can be done by comparing the observed ecosystem status to a purposely defined reference condition. In this paper, a geospatial mode...
To mitigate coastal erosion and harbors siltation, new strategies are required in the immediate term. In fact, even if many traditional solutions are available, their application is usually limited due to economic, environmental and social reasons. This situation is particularly evident in the case of small marinas or in those areas where the local...
A three degrees-of-freedom model based on the potential flow theory was implemented to represent the motion of a slender cylindrical buoy under waves. The model calibration was performed by means of the comparison between the model results and the experiments performed at the Laboratory of Hydraulic Engineering of the University of Bologna (Italy)....
The paper proposes a simplified methodology to track the evolution of vegetation patterns over a central sandbar of the Po River, Italy, by means of a fixed video camera installed on the top of a bridge pier.

Coupled wave – 3D-hydrodynamics model runs are performed to investigate thermal discharge release to coastal areas by means of including nearshore effects of wave-current dynamics. The study area comprises the vicinity of a power plant at Cerano, in South Italy, where cooling industrial waters are released to the sea. The implemented model is calib...
To mitigate coastal erosion and harbors siltation several selective strategies are currently available. Among the traditional solutions, an innovative device, i.e. the “ejector”, characterized by low operative costs, no environmental impact and able to simultaneously counteract both phenomena, was designed and experimentally tested in laboratory an...
Although the importance, sediment siltation represents a very critical barrier for the operability of the harbor of Rodi Garganico (Italy). Due to negative economic impact, in fact, traditional dredging results an unviable solution. For this purpose, an innovative solution, called the “ejector”, is proposed for the specific case. Based on several p...
In recent years, the use of video-monitoring techniques for the evaluation of coastal erosion in maritime areas is significantly increased, due to the diffusion of high-resolution cameras at relatively-low cost (Archetti et al., 2016). The capability of performing several analyses makes video monitoring suitable for applications in coastal research...

Looking downstream, the camera ac-quires images every twelve hours while hourly water levels are derived from a ra-dar hydrometer located 300...
The evolution of coastal and transitional environments depends upon the interplay of human activities and natural drivers, two factors that are strongly connected and many times conflicting. The urge for efficient tools for characterising and predicting the behaviour of such systems is nowadays particularly pressing, especially under the effects of...

In this paper, the performance of different wave generation and absorption methods in computational fluid dynamics (CFD)-based numerical wave tanks (NWTs) is analyzed. The open-source CFD code REEF3D is used, which solves the Reynolds-averaged Navier-Stokes (RANS) equations to simulate two-phase flow problems. The water surface is computed with the...
Studies on coastal boulders transported inland by high‐energy events, as tsunamis, focus mainly on the nature, magnitude and characteristics of past events and contribute to coastal hazard assessments. However, uncertainties on the transport models used in the literature are widely acknowledged.

No other environmental variable of such ecological importance to estuarine and coastal marine ecosystems around the world has changed so drastically, in such a short period of time, as dissolved oxygen in coastal waters. The prevalent methods for counteracting anoxic sea events are indirect measures which aim to cut-down anthropic loads introduced...
The most common methods of counteracting hypoxic events at the bottom sea layers are indirect measures aimed to reduce organic load introduced in the environment. No direct approach has been investigated except the WEBAP and OXYFLUX devices. The estimation of the surface water pumped from such devices is still largely based on physical or empirical...

Coastal areas for anthropic zones are vital economic hubs for tourism, fisheries and recreational activities. These are just some of the businesses which develop and grow many parts of the world. In terms of water quality, the growth of economy, along with the acceleration of climate change makes it necessary for sustainable coastal defense plans....

Extreme met-ocean conditions cause proportioned wave run-up and load on sand dunes which potentially trigger the formation of a fast growing dune breach leading to coastal flooding. The objective of this study is to investigate deterministically how and to what extent waves trigger and drive breaching of sand dunes. The selected study area is Emili...
