Coastal risk forecast system
The run-up and overtopping by sea waves are two of the main processes that threaten coastal structures, leading to flooding, destruction of both property and the environment, and harm to people. To build early warning systems, the consequences and associated risks in the affected areas must be evaluated. It is also important to understand how these two types of spatial information integrate with sensor data sources and the risk assessment methodology. This paper describes the relationship between consequences and risk maps, their role in risk management and how the HIDRALERTA system integrates both aspects in its risk methodology. It describes a case study for Praia da Vito´ria Port, Terceira Island, Azores, Portugal, showing that the main innovations in this system are twofold: it represents the overtopping flow and consequent flooding, which are critical for coastal and port areas protected by maritime structures, and it works also as a risk assessment tool, extremely important for long-term planning and decision-making. Moreover, the implementation of the system considers possible known variability issues, enabling changes in its behaviour as needs arise. This system has the potential to become a useful tool for the management of coastal and port areas, due to its capacity to effectively issue warnings and assess risks.

Estudos em modelo reduzido de obras marítimas da Região Autónoma dos Açores
Atendendo ao seu caráter histórico, o presente artigo insere-se num conjunto de ações proposto pelo Departamento de Hidráulica e Ambiente (DHA) do Laboratório Nacional de Engenharia Civil (LNEC) com vista à comemoração dos 70 anos da sua existência, efeméride que se comemora durante o presente ano de 2018, e visa a apresentação de uma resenha da atividade desenvolvida no âmbito de estudos em modelos físicos de obras marítimas, pelo DHA desde a sua fundação, e para a Região Autónoma dos Açores (RAA). Pela sua insularidade, as populações da (RAA) estão naturalmente ligadas ao mar, nas suas mais diversas vertentes, muito dependendo a sua qualidade de vida das infraestruturas portuárias existentes em cada ilha, que permitem os indispensáveis movimentos de pessoas e de mercadorias e que muito contribuem para a coesão social e económica do arquipélago.Em virtude do papel decisivo assumido pelos portos na RAA, foi ao longo dos anos dada especial atenção à concepção destes equipamentos infraestruturais, tendo o LNEC desempenhado um papel relevante no capítulo reservado à verificação de projetos de obras marítimas de proteção portuária, especialmente através da realização de estudos em modelo físico reduzido, enquanto ferramenta mais válida para a concretização daquele objetivo, quer no passado, quer também no presente. Desde a fundação do Serviço de Hidráulica do LNEC, em 1948, foram inúmeros os estudos em modelo físico reduzido realizados para obras marítimas da RAA. O primeiro estudo em modelo reduzido de que há registo foi iniciado na segunda metade da década de 50, tendo o respetivo relatório do estudo sido publicado em março de 1958. Tratou-se de um estudo em modelo reduzido tridimensional (3D) com vista à definição do lay-out das obras marítimas de proteção do porto de Vila do Porto (Ilha de Santa Maria), em estrito cumprimento de requisitos que haviam sido estabelecidos, do ponto de vista da agitação marítima no interior da bacia portuária.Desde então, o LNEC foi chamado a intervir com a realização de ensaios em modelo reduzido em múltiplas situações, tendo-se assistido a uma especial concentração de atividade a partir do início da década de 80, coincidindo com o grande desenvolvimento portuário registado na Região.Ao longo dos 70 anos de vida do Departamento de Hidráulica e Ambiente (DHA) foram então efetuados, no LNEC e sob a orientação dos seus técnicos, 50 estudos em modelo físico reduzido de obras projetadas para a RAA, para todas as ilhas do arquipélago, com exceção da Ilha do Corvo.

Probabilistic design and reliability analysis of scour protections for offshore windfarms
Scour protection is an important component of fixed bottom foundations for offshore wind turbines. Depending on the hydrodynamic conditions, they might be indispensable to avoid the structural collapse of the foundation due to scour phenomena. The design of scour protections is typically deterministic, which often results in overestimated mean diameters of the armour layer.Moreover, the design methodologies currently applied do not provide a measure of safety associated with the proposed design. The present research proposes a novel methodology to assess the safety of the protection and to perform the probabilistic design of static and dynamic scour protections. A case study based on Horns Rev. 3 offshore wind farm is used to show how to select the mean stone diameter according to a pre-defined probability of failure of the protection. The results show that a dynamic scour protection could be safely designed with a reduction of the mean stone diameter up to 15 cm, when compared with the statically stable protection.

Risk assessment of coastal flood in a site of special scientific interest
The Canary Islands have a long coastline with varying levels of exposure to severe sea conditions. Frequent states of alert and emergency in some parts of their coastline are commonly related to the occurrence of extreme wave conditions. Among the phenomena directly driven by the waves when reaching the shore are the wave run-up and overtopping. Both the study of the flood level, including its variability, and the associated risks are key tools in the planning and management of coastal zones. The aim of this research is to examine the probability of occurrence of run-up events capable of exceeding different topographical levels, for estimating the risk level associated with flooding of the different areas in which the Boca Barranco Beach can be divided, in terms of their nature and use. This beach is located on the island of Gran Canaria, Spain, and is part of the site of scientific interest of Jinámar. A large wave dataset is used as input to a high-resolution numerical model for propagating offshore wave conditions to shallow waters in the study area. Furthermore, the morphology of the study area is reproduced by combining different bathymetric databases. Finally, the probability of occurrence of different levels of run-up and the corresponding levels of consequences are assigned, to assess the flood risk in the different areas of the beach, which are presented in a risk map of flooding in the study area.

Rubble mound breakwater damage assessment through stereo photogrammetry in physical scale laboratory tests
Scale-model tests are usually required to evaluate the hydraulic and structural behavior of proposed rubble-mound breakwater designs. In order to speed up and ease the armor layer damage assessment, we developed a technique based on stereo photogrammetry. A key feature of this technique is its ability to compensate for the refraction in the air-water interface, thus producing a survey of the envelope of the armor layer without the need to empty the wave flume or wave basin where the scale model tests are carried out. This article describes this technique and the tests made to establish confidence in it and in the damage evaluation on a breakwater scale model. Results led to an error estimation of only fractions of a centimeter.

Utilização conjunta de ferramentas neuronais e SIG na avaliação da inundação do porto e baía da Praia da Vitória
O HIDRALERTA é um sistema de previsão, alerta e avaliação do risco de galgamentos/inundação em zonas costeiras e portuárias, partindo da utilização de medições/previsões da agitação marítima para calcular o galgamento/inundação nessas zonas. O cálculo dos caudais médios galgados sobre uma estrutura marítima é efetuado através de ferramentas neuronais e/ou fórmulas empíricas, que não permitem definir a distribuição espacial desse caudal atrás da estrutura.Este artigo apresenta a aplicação ao porto/baía da Praia da Vitória, Açores, de um método expedito para modelar essa distribuição espacial, recorrendo a ferramentas SIG. Foi estabelecida uma relação entre a cota de inundação e o volume galgado de água através da utilização de um modelo digital de terreno. Este trabalho representa um primeiro passo na elaboração de um mapa de risco associado ao galgamento costeiro.

Monitoring the Madeira airport protection breakwater using visual and Unmanned Aerial Vehicle observations
An aerial monitoring system was developed for the maritime structures protecting the foundation columns of the airport infrastructure of the Madeira Island Airport, in the scope of research project MEGE, to complement the already existing monitoring program of visual observations. For the aerial monitoring of the berm breakwater, with about 770 m in length, a fast data acquisition system was envisaged. Imaging techniques acquired through a high-resolution camera coupled to an unmanned aerial vehicle (UAV) were used, which allowed for a very fast and efficient automated procedure, compatible with the difficult accessibility to the structure on the seaside. Point clouds corresponding to the breakwater geometry were obtained from the set of aerial images from the camera on board of the UAV, using photogrammetric techniques. In this paper, the two complementary parts of the monitoring of this structure are described and corresponding results are shown.

Safety System for Ships in Harbours
SAFEPORT safety system aims at forecasting and alerting, on a regular basis, emergency situations regarding ships operation in port areas caused by extreme weather-oceanographic conditions. It uses forecasts provided offshore of the area under study of sea agitation, wind and tide. The characterization of the response of the free and moored ships at a berth is performed using the numerical package SWAMS. The system issue alerts, through danger levels associated with risk levels of exceedance of recommended values for movements and forces imposed on ship mooring systems. SAFEPORT can be adapted to any port. So far, it has been developed and adapted to three terminals of the port of Sines, where three different ships were simulated. This paper presents the developments made to date of the safety system, which includes tests performed in storm situations. The numerical models run every day, in real-time mode, in a computer cluster and the system provide forecast results for the next 72 hours. The results are disseminated on a web page and a mobile application in a variety of formats. It was concluded that the SAFEPORT safety system issued alerts according to the observed reality during the storm Dora. It has also been shown to be a computer tool for the optimization of ship mooring systems. The system is currently in testing and validation phase therefore, forecasts should be interpreted as indicative.

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.

Evaluation of wave overtopping consequences for risk assessment using ANP methodology
Adverse sea conditions can cause emergency situations associated to wave overtopping, which endanger the safety of people and goods, with negative impacts for society, the economy and the environment. Therefore, a methodology to assess the overtopping risk in port and coastal areas is essential for a proper planning and management of these areas.The Portuguese National Laboratory for Civil Engineering (LNEC) has been developing the HIDRALERTA system, an integrated decision-support tool for port and coastal management, which focus in preventing and supporting the management of emergency situations and the long-term planning of interventions in the study areas. It enables the user to calculate the risk for various port and coastal activities, starting with the characterization of sea-waves, wind field and tide levels at the study regions.HIDRALERTA was already tested at different places in Portugal: Costa da Caparica beach, in Almada, and port of Praia da Vitória, in the Azores. However, in both cases, the evaluation of wave overtopping / flooding consequences was carried out using a quite simple approach. In fact, such consequences were assessed only at a global and qualitative level, based on information provided by the responsible authorities.This paper aims at testing a quantitative methodology to evaluate overtopping consequences: the Analytic Network Process (ANP). This methodology was proposed to solve complex decision-making problems and its objective is to calculate the priorities among decision elements which will define their final weights on the consequences. The ANP approach can produce interdependencies between criteria and compute the respective weight of each criterion. Such a network model with dependence and feedback improves the priorities derived from judgements and makes prediction more accurate. So, the ANP allows comparison among clusters of elements. Furthermore, in this methodology we take into account the impacts of alternatives on the importance of criteria, by normalizing the comparison matrix. Thus, the given alternatives can influence the ranking of criteria.Application of the ANP methodology to the case study of Praia da Vitória port is presented and a consequences level map is obtained.

Sistema de alerta para a navegação em portos
Apresenta-se um novo sistema de alerta para navios amarrados em portos que se encontra em desenvolvimento no Laboratório Nacional de Engenharia Civil. O sistema SWAMS_ALERTA é um sistema de previsão e alerta baseado na avaliação do risco associado ao comportamento de navios amarrados em zonas portuárias.Os riscos associados a navios amarrados decorrem de movimentos excessivos, quer no plano horizontal, quer no plano vertical. Estes movimentos podem condicionar as atividades portuárias, nomeadamente cargas e descargas, mas em casos extremos podem levar à ocorrência de situações de emergência, tais como rotura de cabos, rotura de cabeços de amarração ou até colisões com o cais. As consequências deste tipo de situações envolvem sempre grandes prejuízos materiais e por vezes humanos.O sistema SWAMS_ALERTA utiliza as medições e previsões de agitação marítima para a determinação dos seus efeitos em termos de movimentos nos seis graus de liberdade e forças nas amarras e defensas quando o navio se encontra estacionado no cais. Para tal, o sistema recorre a uma série de modelos numéricos, interligados entre si. A comparação destes valores com valores máximos admissíveis pré-estabelecidos permite a avaliação, em tempo real, de situações de emergência e a emissão de alertas dirigidos às entidades portuárias.O sistema é constituído por 4 módulos:I
