Energy rate balance applied to coastal engineering problems by using RANS-VoF models in numerical wave flumes 
Nowadays, the use of RANS-based models for simulating numerical wave flumes and studying coastal engineering structures is common and allows investigating accurately phenomena that occur in current/wavestructure interactions. Comprehension of energy transformations in these processes can support designers tooptimize the system. In this study, a methodology to evaluate the terms of the energy rate balance in coastalengineering problems is developed. The methodology is applied to the propagation of regular waves in numericalwave flumes, onshore oscillating water column wave energy converter integrated into a vertical breakwater, andtwo types of rubble-mound breakwaters. The direct determination of the energy rate due to viscous and urbulencelosses and the porous resistance in rubble-mound breakwaters are carried out by time integration insidethe computational domain. Besides, the reflected and transmitted energy rates in the flume are calculated bymeans of this methodology, instead of the standard gauge methods, commonly used in physical and numericalflumes. Complementary, studies may be carried out for random incident waves and the methodology can beapplied to 3D wave tanks.

An assessment of 3D scanning methods in physical models
The evaluation of damage progression caused by wave action on physical models of rubble-mound breakwaters can be accomplished through two types of methods: quantifying the movements and falls of the resistant armor elements by visual inspection (the traditional, classical method) or determining the eroded volumes and depths between consecutive surveys of armor layers using sensors and photogrammetric methods (3D scanning methods). Of the latter, one may use techniques such as the so-called "Kinect", "Photogrammetry" and "LiDAR". The end-product of these techniques is, among others, point clouds, which allow obtaining three-dimensional surface models. In this paper, four of the latter techniques (3D scanning methods) are briefly described, and a comparison is made between them regarding their usability in current tests, their advantages and disadvantages, among themselves for a study case of the physical 3D model of the Ericeira breakwater. In evaluating survey quality across the four methods, RMSE (root mean square error) was employed to align obtained point clouds with ground control points (GCP). Notably, Photogrammetry, Kinect, and Azure techniques showed excellent RMSE values. Conversely, the LiDAR-derived-method cloud, using a smartphone with LiDAR sensor and 3dScanner app, fails to yield acceptable and accurate results for the research objectives of this paper.

Development of a Bayesian network-based early warning system for storm-driven coastal erosion
Coastal hazards such as flooding and erosion can cause large economic and human losses. Under this threat, early warning systems can be very cost-effective solutions for disaster preparation. The goal of this study was to develop, test, and implement an operational coastal erosion early warning system supported by a particular method of machine learning. Thus, the system combines Bayesian Networks, and state-of-the-art numerical models, such as XBeach and SWAN, to predict storm erosion impacts in urbanized areas. This system was developed in two phases. In the development phase, all information required to apply the machine learning method was generated including the definition of hundreds of oceanic synthetic storms, modeling of the erosion caused by these storms, and characterization of the impact levels according to a newly defined eerosion iimpact index. This adimensional index relates the distance from the edge of the dune/beach scarp to buildings and the height of that scarp. Finally, a Bayesian Network that acted as a surrogate of the previously generated information was built. After the training of the network, the conditional probability tables were created. These tables constituted the ground knowledge to make the predictions in the second phase. This methodology was validated (1) by comparing 6-h predictions obtained with the Bayesian Network and with process-based models, the latest considered as the benchmark, and (2) by assessing the predictive skills of the Bayesian Network through the unbiased iterative k-fold cross-validation procedure. Regarding the first comparison, the analysis considered the entire duration of three large storms whose return periods were 10, 16, and 25 years, and it was observed that the Bayesian Network correctly predicted between 64% and 72% of the impacts during the course of the storms, depending on the area analyzed. Importantly, this method was also able to identify when the hazardous conditions disappeared after predicting potential consequences. Regarding the Regarding the second validation approach, second validation approach, the k-fold cross-validation procedure was applied to the peak of a set of varying storms and it demonstrated that the predictive skills were maximized (63%

Experimental study of an onshore dual chamber oscillating water column device
A wave flume is used to study a scaled model of a stepped bottom dual-chamber Oscillating Water Column (OWC) installed onshore. Compared to traditional single-chamber OWCs, the use of dual-chambers is expected to widen the range of sea states in which the OWC is more efficient, and the step, in front of the first chamber, boosts the capturing energy capacity of the device. The Power Take-Off (PTO) system is modelled as an air opening in the pneumatic chambers. Several experiments combining regular incident waves and PTO damping conditions are performed. Results of the amplitudes of the free surface elevations inside the chambers show that the device can amplify the incident wave amplitude up to 1.57 times in chamber 2. Results of the primary efficiency show that the device is highly dependent on the PTO damping characteristics and can reach around 40% for a wide range of wave periods. Results of the reflection analysis show that the reflection coefficient is also dependent on the PTO damping characteristics but remain lower than 0.6 for all the studied cases. Sloshing phenomenon (mostly in the cross-section direction) was observed for a wavelength close to the cross-section dimension, impacting negatively on the device pneumatic performance.

Experimental study on drag coefficient of flexible vegetation under non-breaking waves
Laboratory experiments of wave propagation over rigid and flexible vegetation fields, with the same configurations, were conducted to understand the effect of vegetation flexibility on the drag coefficient (CD). The direct method and the least squares method (LSM), based on force and flow measurements, are applied to calculate the CD in the experimental conditions. The formulations of both methods are extended to estimate the CD for flexible vegetation cases. A video analysis was performed to account for the swaying motion. Typically, wave dissipation is lower for flexible than for rigid vegetation of the same configuration, under the same flow condition. Therefore, a proportional effect in the corresponding CD results, obtained from common CD calibration to wave dissipation without considering vegetation motion, is usually observed. However, the present results show that although the wave dissipation was 34% lower for flexible relative to rigid vegetation, the respective CD values were close. CD estimations considering vegetation motion and inertia suggest that CD of flexible vegetation was up to 13% higher relative to rigid vegetation. Accounting for inertia reduced the CD for rigid vegetation up to 7%, while raised the CD for flexible vegetation up to 13%.

Wave runup and overtopping assessment by using video methodologies in physical models
Physical modelling is one of the tools to help characterize wave runup and overtopping in maritime structures. Usually, the determination of wave runup is made by using resistive wave gauges along the breakwater slope while the evaluation of overtopping volumes (individual or total) is made by weighing the water overtopped with a scale that is collected in a reservoir installed on this scale.Nowadays, non-intrusive methodologies for the assessment of those parameters are being used, due to their simplicity and low cost. Video cameras, constitute a good alternative to old methods; however, their performance depends essentially on the post-processing methodologies used.The present paper presents the application of the Timestack methodology done so far, in the evaluation of: wave runup in 2D and 3D physical tests. The video-derived statistical parameters of wave runup (Rumax, Rumin, Rumed e Ru2%) are compared with the corresponded ones obtained with resistive wave gauges. The total water volume and the average overtopping flow rate from video data is compared with the one collected by a reservoir. Those cases will illustrate the advantages and drawbacks associated with Timestack methodology.

AVALIAÇÃO DE VOLUMES INDIVIDUAIS GALGADOS NA ERICEIRA COM O MODELO NUMÉRICO SWASH
Neste trabalho, utilizou-se o modelo numérico SWASH para avaliar os volumes galgados em ondas individuais no quebra-mar da Ericeira. Começa-se por definir o valor do coeficiente de Manning a utilizar no talude do quebra-mar, para simular perda de energia provocada pela rugosidade e pela percolação no processo do galgamento, comparando o volume galgado previsto pelo modelo numérico com os valores medidos nos ensaios com modelo físico realizados no LNEC, para um dado estado de agitação. Depois, para ondas selecionadas do mesmo estado de agitação verifica-se se o modelo numérico fornece valores semelhantes aos do mesmo modelo físico.

Estudos e projetos do prolongamento do quebra-mar exterior do Porto de Leixões
Entre 2016 e 2020 foram realizados os Estudos e Projetos e Estudos de Impacto Ambiental (EIA) dos projetos do Prolongamento do Quebra-mar Exterior e das Acessibilidades Marítimas do Porto de Leixões, os quais envolveram ensaios em modelo físico reduzido realizados no Laboratório Nacional de Engenharia Civil (LNEC) entre outubro 2016 e abril 2017, encontrando-se atualmente em curso a respetiva empreitada de construção. Os estudos, projetos e ensaios bi e tridimensionais em modelo reduzido do Prolongamento do Quebra-mar Exterior em cerca de 300 m, destacam-se essencialmente por se tratar de um quebra-mar sujeito a um regime de agitação consideravelmente severo e por envolver o uso de blocos de betão de alta densidade (peso especifico de 27,2 kN/m3 a 32 kN/m3 ) do tipo Antifer, cujo comportamento idráulico e estrutural, apesar da experiência adquirida na utilização deste tipo de blocos no Molhe Sul da Barra do Rio Douro (também com betão com peso especifico de 32 kN/m3) e no Molhe Leste de Sines (peso especifico de 25,4 kN/m3 a 30,8 kN/m3), ainda se reveste de alguma complexidade. No âmbito destes estudos realizou-se inicialmente o Estudo Prévio (EP), com base no qual se realizaram os ensaios bi e tridimensionais, e em simultâneo com estes últimos, realizou-se o Projeto de Execução (PE). Neste, e com o objetivo de aumentar a segurança da estrutura, adotaram-se generalizadamente blocos de maior peso do que os ensaiados.

Data Storage Report. RECIPE Task 8.2: Overtopping events in breakwaters under climate change scenarios
Reliable prediction of wave run-up/overtopping and structure damage is a key task in the design and safety assessment of coastal and harbor structures. Run-up/overtopping and damage must be below acceptable limits, both in extreme and in normal operating conditions, to guarantee the stability of the structure and the safety of people and assets on and behind the structure. The mean-sea-level rise caused by climate change and its effects on wave climate may increase the number and intensity of run-up/overtopping events and make the existing coastal/harbor structures more vulnerable to damage.Accurate estimates, through physical modelling, of the statistics of overtopping waves for a set of climate change conditions, are needed. The research project HYDRALAB+ (H2020-INFRAIA-2014-2015) gathers an advanced network of environmental hydraulic institutes in Europe, which provides access to a suite of environmental hydraulic facilities. They play a vital role in the development of climate change adaptation strategies, by allowing the direct testing of adaptation measures and by providing data for numerical model calibration and validation. The use of physical (scale) models allows the simulation of extreme events as they are now, and as they are projected to be under different climate change scenarios.The enclosed dataset refers to the experimental work developed at LNEC within HYDRALAB+ and considers 2D damage and overtopping tests for a rock armor slope, with four different approaches to represent storms. Data of free surface elevation, overtopping and damage is presented.
