An Early Warning System for Coastal Risks Assessment
Storms impacting sandy coastal areas produce hazards such as erosion and overwash that, in turn, promote risk to life and property damage in occupied areas. Coastal damage and risks willincrease in the future not only in association with climate change but also due to the growinghuman occupation in coastal areas (van Dongeren et al., 2018). Since the threatened coastal areas are often densely populated, there is a need to implement measures to prevent risks. One of such measures is the use of Early Warning Systems (EWS) that anticipate expected risks and, therefore, work as management tools to minimize or avoid disaster. This work presents the basis of an EWS prototype to alert about the potential consequences of overwash/overtopping and erosion induced by storms, in coastal areas.

Cálculo do galgamento na estrutura de defesa aderente da Vagueira utilizando o modelo SWASH
A praia da Vagueira está localizada no Município de Vagos, distrito de Aveiro e é protegida por uma estruturade defesa frontal aderente que foi requalificada em 2015, com alteamento da sua cota de coroamento para + 10 m(ZH), devido à ocorrência de inundações na zona por ela protegida. Para caracterizar o galgamento com a estrutura atual, aplicou-se o modelo numérico SWASH a uma secção desta estrutura, simulando-se os temporais ocorridos entre 1979 e 2018 que, segundo as fórmulas comumente utilizadas para este tipo de estrutura, dariam galgamentos significativos. Assim, nesta comunicação apresenta-se o modelo utilizado, as características da estrutura de defesa aderente e as condições de agitação e nível de mar utilizadas nas simulações. Os resultados obtidos com o SWASH são comparados com os resultados de várias fórmulas empíricas. Para todas as condições testadas, as fórmulas empíricas apresentam sempre caudais médios de galgamento não nulos, enquanto o SWASH apenas origina caudais médios de galgamento superiores a zero quando o espraiamento máximo não atinge o coroamento da estrutura. Consequentemente, a utilização dos resultados das fórmulas empíricas para a emissão de alertas pode conduzir a situações de alarme que não correspondem à realidade.

Conceptual and quantitative categorization of wave
Beaches combined with sloping structures are frequently the frst element of defense to protect urban areas from the impact of extreme coastal fooding events. However, these structures are rarely designed for null wave overtopping discharges, accepting that waves can pass above the crest and threat exposed elements in hinterland areas, such as pedestrians, urban elements and buildings, and vehicles. To reduce risks, Early Warning Systems (EWSs) can be used to anticipate and minimize the impacts of fooding episodes on those elements. A key aspect of these systems is the defnition of non-admissible discharge levels that trigger signifcant impacts. However, large discrepancies in defning these discharge levels and the associated impacts are found among the existing methods to assess foodings. Due to the lack of standardization, a new conceptual and quantitative four-level (from no-impact to high-impact) categorization of food warnings (EW-Coast) is proposed. EW-Coast integrates and unifes previous methods and builds on them by incorporating feld-based information. Thus, the new categorization successfully predicted the impact level on 70%, 82%, and 85% of the overtopping episodes afecting pedestrians, urban elements and buildings, and vehicles, respectively. This demonstrates its suitability to support EWSs in areas vulnerable to wave-induced fooding.

Damage Evolution in Physical Scale Model Tests of a Stretch of the Breakwater of Peniche Harbour.
During physical scale model tests of rubble mound breakwaters, the assessment of the eroded volume of the armour layer subjected to incident sea waves can be determined from consecutive surveys of the surface of the armour layer after each test run. This enables one to assess the damage level of the struc ture by comparing erosion profiles and by the eroded volume between consecutive surveys of the tested section. The present study aimed to evaluate the damage evolu tion of a section of the Peniche harbour west breakwater, whose armour layer is made of tetrapods, A dimensionless damage parameter was computed, based on the eroded volume at the end of each test. The test program consisted of three test series (A, B and C) with different durations and wave conditions sequences, considering the low-water level (water depth of 0.20 m at the toe of the structure) and high-water level (0.24 m) and sea states with peak periods Tp = 1.70 s and Tp = 1.98 s and significant wave heights, Hm0, ranging between 0.12 m and 0.19 m. The model was built and operated according to Froude

Damage Evolution Prediction during 2D Scale-Model Tests of a Rubble-Mound Breakwater: A Case Study of Ericeira
Melby presents a formula to predict damage evolution in rubble-mound breakwaterswhose armour layer is made of rock, based on the erosion measured in scale-model tests and thecharacteristics of the incident sea waves in such tests. However, this formula is only valid for armourlayers made of rock and for the range of tested sea states. The present work aims to show howthe Melby methodology can be used to establish a similar formula for the armour layer damageevolution in a rubble-mound breakwater where tetrapods are employed. For that, a long-durationtest series is conducted with a 1:50 scale model of the quay section of the Ericeira Harbour breakwater.The eroded volume of the armour layer was measured using a Kinect position sensor. The damageparameter values measured in the experiments are lower than those predicted by the formulationfor rock armour layers. New ap and b coefficients for the Melby formula for the tested armour layerwere established based on the minimum root mean square error between the measured and thepredicted damage. This work shows also that it is possible to assess the damage evolution in scale model tests with rubble-mound breakwaters by computing the eroded volume and subsequently, thedimensionless damage parameter based on the equivalent removed armour units.

Development of a Bayesian networks-based early warning system for wave-induced flooding
Coastal flooding prediction systems can be an efficient risk-reduction instrument. The goal of this study was to design, build, test, and implement a wave-induced flooding early warning system in urban areas fronted by sandy beaches. The system utilizes a novel approach that combines Bayesian Networks and numerical models (SWAN + XBeach) and was developed in two phases. In the development phase, firstly, the learning information was generated including the creation of oceanic conditions, modeling overtopping discharges, the haracterization of the associated im pacts (no, low, moderate and high) in pedestrians, urban components and buildings, and vehicles, and secondly, the Bayesian Networks were designed that surrogated the previously generated information. After their training, the conditional probability tables were created representing the foundation to make predictions in the operational phase. This methodology was validated for several historical events which hit the study area (Praia de Faro, Portugal), and the system correctly predicted the impact level of around 80% of the cases. Also, the predictive skills varied depending on the level, with the no and high impact levels overcoming the intermediate levels. In terms of efficiency, one simulation (deterministic) of coastal flooding for 72 h by running SWAN + XBeach operationally would take more than two days on a one-logical processor workstation, while the current approach can provide quasi-instantaneously predictions for that period, including probability distributions. Moreover, the two-working phase approach is very flexible enabling the inclusion of additional features such as social components representing a powerful tool for risk reduction in coastal communities.

Implementation of the SWASH model into HIDRALERTA system
Early warning systems are an important tool for local authorities to detect emergency situations in advance and initiate the necessary safety measure. These systems often depend on numerical models to estimate wave overtopping in the affected areas. The SWASH model has shown to deliver good results in recent overtopping studies. The To-SEAlert project has the aim of increasing the efficiency, robustness and reliability of the HIDRALERTA early warning system. This study shows a first intent to implement the SWASH model to simulate wave overtopping for the Ericeira prototype. SWASH was implemented for one breakwater profile used to simulate the overtopping discharge and evaluate the associated risk levels. It was compared to the current approach used in HIDRALERTA, which resorts to a neural network trained with a physical modeling database, NN_OVERTOPPING2. Finally, both approaches were compared with previously analyzed video images of the breakwater. The results showed that SWASH generally overestimates overtopping and is not in good agreement with the video images. NN_OVERTOPPING2 has a better agreement with the video images. A possible reason for the overestimation might be the wave direction, which cannot be included in one-dimensional simulations in SWASH.

Analytical and numerical modelling of wave dissipation over rigid and flexible vegetation in a flume: Drag coefficient calibration
Coastal vegetation can contribute to protect the coasts from sea wave action, as controlling local biology and morphodynamics. A common way to estimate the wave energy dissipation over vegetation is to use the Mendez and Losada (2004) analytical formulation in combination with the calibrated bulk drag coefficient parameter (CD). However, an excessive range of CD values is found in the literature related to same Reynolds (Re) or Keulegan-Carpenter (KC) numbers. This may be due to a lack of universality of the empirical equations proposed and/or limitations of the analytical model. The numerical model SWASH (Zijlema et al., 2011) characterises wave dissipation over vegetation fields (Suzuki et al., 2019, 2022; Reis et al., 2020) considering the influence of the drag, inertia, and porous effects on cylindrical structures. Potentially, SWASH offers enhanced capacities to describe the physical processes involved and to calibrate associated CD values. Wave dissipation over vegetation data was collected by performing laboratory flume experiments, enabling an ideal control of the study conditions. The analytical formulation and the SWASH numerical model are applied to estimate the wave dissipation obtained in the experiments, through the calibration of the CD.The objective of this study is to investigate: i) how the analytical and SWASH models can represent the experimental wave dissipation, and ii) the calibrated CD values obtained from each modelling approach.

Exploring Wave-Vegetation Interaction At Blade Scale: A Comprehensive Analysis Of A Flexible Cylinder Through Experimental Data And A Direct Numerical Simulation
Aquatic vegetation in the littoral zone, particularly seagrass, is gaining increasing recognition for its net positive impact on the hosting environment. This recognition is rooted in its capacity to absorb wave energy, regulate water flow, and manage nutrient levels, sedimentation and accretion. Thus, there is a growing interest in integrating seagrass as a key component of a comprehensive climate-conscious strategy (Ondiviela et al., 2014). An effective approach to quantify the positive potential of seagrasses in altering coastal wave dynamics is by using numerical models. These numerical models operate at various spatio- temporal scales, ranging from large domains and multiple years to just a few regular waves in high resolution CFD numerical simulations. Zeller et al. (2014) classified these models, operating at different scales into three categories, each addressing the wave-vegetation interaction at a distinct scale: (1) blade scale, (2) meadow scale, and (3) ecosystem scale. The aim of the present study is to investigate the interaction between waves and vegetation at the blade scale. The primary objectives are two: first, to introduce a direct numerical technique that involves a two-way coupling between a fluid solver and a structural solver, and second, to present novel experimental data for a single flexible cylinder (Reis, 2022) serving as validation for the present (and future) numerical model(s).

Analysis of run-up and overtopping in coastal protection structures: video-monitoring techniques
Marginal protection structures or adherent longitudinal defenses, whose main function is to mitigate overtopping, are structures parallel to the coast. They are intended to serve as protection and shelter against flooding, due to overtopping, dissipating wave energy in their interaction with the structure, and in areas strongly affected by coastal erosion, minimizing the risk of damage to roads, walkways or buildings in the proximity.The evaluation of run-up and overtopping in marginal protection structures is determined according to the conditions of incident sea agitation and the characteristics of the structure, being fundamental for the design of new structures and in the verification of the safety of existing structures.

Assessment of 3D reconstruction techniques in physical models
Damage progression in wave-exposed physical models of rubble-mound breakwaters can be assessed using two methods: traditional quantification of armor element movements or newer approaches involving non-intrusive surveys, utilizing photogrammetry, RGB sensors, Time of Flight depth sensors, and LiDAR laser scanning sensors to determine eroded volumes and depths between consecutive armor layer surveys. These techniques allow for the creation of three-dimensional surface models with varying accuracy, depending on survey conditions and post-processing methodologies. The performance, suitability, and usability of these techniques in assessing damage progression are comparatively evaluated. Furthermore, the advantages and disadvantages of each technique are identified, and a sensitivity analysis is presented for each one.

Avaliação de desempenho de técnicas de reconstituição 3D aplicadas a modelos físicos de quebra-mares
A avaliação da evolução dos danos causados pela agitação incidente em modelos físicos de quebra-mares de taludes pode ser efetuada através da quantificação de movimentos e quedas dos elementos do manto resistente (métodos tradicionais), ou pela determinação de volumes e profundidades erodidas entre levantamentos consecutivos dos respetivos taludes (métodos mais atuais). Para se efetuarem esses levantamentos dos taludes, podem aplicar-se técnicas fotogramétricas com sensores RGB, sensores de profundidade baseados na metodologia ToF (Time of Flight) e sensores de laser LiDAR (Light Detection And Ranging).No presente trabalho, aplicam-se essas técnicas ao modelo físico do quebra-mar do porto da Ericeira, que está presentemente a ser ensaiado no LNEC, e avalia-se, comparativamente, o respetivo desempenho, adequabilidade e usabilidade na determinação da evolução dos danos, identificando vantagens e desvantagens de cada uma destas técnicas.

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.
