Early warning system for floods at estuarine areas: combining artificial intell...
Melo, Willian Weber; Iglesias, Isabel; Pinho, José L. S.Floods are among the most common natural disasters, causing countless losses every year worldwide and demanding urgent measures to mitigate their impacts. This study proposes a novel combination of artificial intelligence and process-based models to construct a flood early warning system (FEWS) for estuarine regions. Using streamflow and rainfall data, a deep learning model with long short-term memory layers wa...
Optimizing coastal protection: Nature-based engineering for longitudinal drift ...
Vieira, Bárbara Filipa Vasquez; Pinho, José L. S.; Barros, Joaquim A. O.; Carmo, José Antunes doTraditional hard engineering solutions have shown weaknesses in mitigating erosion processes in vulnerable coastal areas, contributing in some cases to their aggravation, which makes it necessary to study innovative nature-based engineering solutions. This research deals with an in-depth analysis of hydro-morphodynamic modelling results for optimizing the geometry of maritime structures under longitudinal drift...
A data model to forecast the morphological evolution of multiple beach profiles
Melo, Willian Weber; Pinho, José L. S.; Iglesias, IsabelBeaches are a natural defense against extreme events, such as storms and hurricanes, whose intensity and fre quency are expected to increase in the future due to climate change. In this context, models that forecast the morphological evolution of coastal areas can be used to anticipate the effects of future scenarios, allowing early action to mitigate the damage caused by extreme events. Hence, this study inclu...
Performance assessment and indicators for agricultural water management - a review
Ahmad, Muhammad Tajuri; Haie, Naim; Gonçalves, José Manuel; Pinho, José L. S.; Yen, Haw; Yakubu, Mahadi Lawan; Mohammed, Murtala Uba; Suleimana, AiubaThe complexity of irrigation systems and the need to adapt them to uncertainties requires developing approaches to synthesize their performances. This paper reviews performance assessment and indicators for agricultural water systems. It is aimed at finding various methods and indices used for irrigation performance assessment and standard classes for their characterization. The global application of the metric...
Semicircular coastal defence structures: impact of gap spacing on shoreline dyn...
Vieira, Bárbara Filipa Vasquez; Pinho, José L. S.; Barros, Joaquim A. O.Coastal erosion poses significant challenges to shoreline management, exacerbated by rising sea levels and changing climate patterns. This study investigates the influence of gap spacing between semicircular coastal defence structures on shoreline dynamics during storm events. The innovative design of these structures aims to induce a drift reversal of prevalent sediment transport while avoiding interruption of...
Análise comparativa do desempenho de uma estrutura inovadora de proteção costei...
Vieira, Bárbara Filipa Vasquez; Pinho, José L. S.; Barros, Joaquim A. O.As soluções tradicionais de engenharia têm demonstrado fragilidades na mitigação dos processos erosivos em zonas litorais vulneráveis, contribuindo, em alguns casos, para o seu agravamento. No presente trabalho, apresentam-se resultados de modelação hidro-morfodinâmica de um estudo comparativo do desempenho de uma estrutura marítima inovadora com o de uma estrutura tradicional (esporão), em condições de tempest...
Coastal morphodynamic emulator for early warning short-term forecasts
Weber de Melo, Willian; Pinho, José L. S.; Iglesias, IsabelThe use of numerical models to anticipate the effects of floods and storms in coastal regions is essential to mitigate the damages of these natural disasters. However, local studies require high spatial and temporal resolution numerical models, limiting their use due to the involved high computational costs. This constraint becomes even more critical when these models are used for real-time monitoring and warni...
Innovative nature-based structures for coastal erosion protection
Vieira, Bárbara Filipa Vasquez; Pinho, José L. S.; Barros, Joaquim A. O.; Ventura-Gouveia, A.This research work presents nature-based innovative structures for addressing coastal erosion mitigation, based on the observation of alongshore drift reversal phenomena. Hydro-morphodynamics and wave climate predictions for storm conditions near the Iberian Peninsula shoreline were analysed for defining an optimized maritime structure geometry. Full-scale observation data and numerical modelling using Delft3D,...
Assessment of the potential for hydrokinetic energy production in the Douro riv...
Cruz, M.; Henriques, R.; Pinho, José L. S.; Avilez-Valente, P.; Bio, A.; Iglesias, I.For being densely populated and urbanized, and for concentrating high-value economic activities, estuarine regions have an increased energy demand, which boosts the claim for new, efficient, renewable, and safe energy production. Among these technologies, hydrokinetic energy conversion systems are potentially well-suited for estuaries. However, in the actual context of climate change, it is important to know ho...
