Monitoring is known to be the basis for coastal planning and management studies, for verifying the interventions effects and for forecasting the future state of beaches. There are several proxies that must be considered in the definition of a monitoring plan, such as the spatial and temporal extension of the monitoring activities, the types of data and their required accuracy values, the acquisition frequency of the data and perhaps the available budget to invest are among the most important aspects. The pr

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 economy is strongly affected by harbor operation such as in the case of the port of the municipality of Cervia (Italy). To solve the problem occurr

The geomorphological characteristics and the seismic, landslide and erosive dynamism of the Italian territory, meant studies on the hydrogeological risk were necessary. Floods and sea storms, combined with anthropic factors, are causes of instability. Under particular climatic, geographical and geomorphological conditions, these events occur simultaneously, increasing their effects. Reggio Calabria, a metropolitan city in the south of Italy, is located in a particularly complex context. The city is flanked

In the field of Engineering, research has conveniently exploited the fluids for energy production. The possibility to use marine renewable energy is still under development, in particular, among the wave energy converter devices the U-OWC systems are the most promising. The main objective of this work is to validate a numerical model with an experimental campaign that aims to simulate the flow field in front of the breakwater and inside the U-OWC. The tests were carried out to understand the hydrodynamic be

The aim of this paper is to investigate the role in the groundwater level dynamics played by drains of a Beach Drainage System (BDS) with different nominal diameters.Three different cases are considered: drained beach without incoming waves; undrained beach with incoming waves, and drained beach with incoming waves. Hence, a preliminary numerical investigation on the hydrodynamics inside a sandy beach is carried out, accounting for the presence of both short water waves and a BDS. The (Volume Averaged) Reyn

The current program of Systematic Observation of Maritime Works (OSOM+), under development at the National Laboratory for Civil Engineering (LNEC), is essentially applied to rubble mound breakwaters. The OSOM’s main objective is to monitor the behaviour of maritime structures under inspection and recommend timely interventions for their maintenance and/or repair as to properly maintain its function during its lifetime. There are four main components of the OSOM+ program, namely: the periodic visual inspec

Climate change impact assessment is vital in order to investigate not only the change of average wind and wave climate, but also the extreme events. Such kind of events can affect the activities in nearshore areas such as marine operation, as well as on design of coastal and marine structures. In this research, longterm assessment of wind and wave data has been conducted to determine the effect of climate change by comparing the dataset for historical and future projections. The analysis has been done mainl

A series of numerical experiments were carried out to perform a sensitivity analysis for existing exponential empirical formulas for pore pressure distribution inside the breakwater core. The Forchheimer equation was solved using a CFD modeling (Flow3D) along with the official license from the Flow Science, Inc. Pore pressure field observations of Zeebrugge breakwater core were used to calibrate the numerical model. Results of sensitivity analysis represented the wave period as an effective parameter on wav

Several authors have proposed guidelines on how to consider the effects of oblique waves on the stability of armour layers of rubble-mound breakwaters. Especially for very oblique waves, for which the increase in stability is the largest, limited data are available. Under the scope of the HYDRALAB+ transnational access project “RODBreak”, experiments were conducted in a tank at the Marienwerder facilities of the Leibnitz University Hannover (LUH), comprising measurements of sea waves, runup, overtopping

The paper focuses on the analysis of the sea level rise and storms effects on natural or nourished beach profiles protected by submerged breakwaters. The increase in terms of intensity and frequency of extreme sea storms, and water levels produced by climate change, could lead to a deviation from the original trend of the beach. Typical Adriatic beaches will be considered as realistic study cases and a submerged structure for coastal protection of a natural or artificial (nourishment) beach is analysed in o

In the present work an investigation on combined wavecurrent orthogonal flow over a planar beach is presented. A series of tests have been carried out in an experimental tank, in which a wavemaker coupled with a flow recirculation system allows the superposition of an oscillatory flow over an orthogonal steady current. Waves and current interact over a fixed smooth bed with a 1:25 sloping profile. Current only and wave plus current tests have been performed, during which surface elevation and velocity profi

The RODBreak experiment aimed at characterizing wave runup, overtopping and damage in rubble-mound breakwaters with oblique wave incidence. a stretch of a rubble-mound breakwater was built in the wave basin of the Leibniz Universität Hannover. Under extreme wave conditions, with different incident wave angles (from 40° to 90°), a total of 49 tests were performed. Each test had different testing parameters, such as significant wave height (Hs), peak period (Tp) and wave direction. Also, for each test, dif

The paper illustrates a mid-term geomorphological evolution analysis of the cliff called “Ripe Rosse”, one of the most important rocky coast geosite in the Cilento, Vallo di Diano and Alburni UNESCO Global Geopark. Specifically, the study aims to define the main geological and geomorphological characteristics of the areas in question. High coasts are usually the result of a very long evolution (thousands or even hundreds of thousands of years). This type of high coast is particular, it follows an evolut

This study aims to reproduce the hydrodynamics (waves, currents and sediment transport) in the area surrounding the submerged cooling system of the Latina nuclear power plant (Latium region, Italy) in order to investigate the morphodynamic origin of the observed submarine channel. The bathymetry survey of the area revealed the presence of a rip canyon on the east flank of the structure. This structure is made up of two submerged pipelines, 700 m long, covered by a submerged rubble mound and extends to the -

The present paper describes the experiences gained from the design methodology and operation of a 3D physical model experiment aimed to investigate the dynamic behaviour of a spar buoy floating offshore wind turbine. The physical model consists in a Froude-scaled NREL 5MW reference wind turbine (RWT) supported on the OC3-Hywind floating platform. Experimental tests have been performed at Danish Hydraulic Institute (DHI) offshore wave basin within the European Union-Hydralab+ Initiative, in April 2019. The f
