This study aims to contribute to more sustainable mobility solutions by proposing robustand actionable methods to assess the resilience of a multimodal transport system. Resilience is seenin a dynamic lean setting, looking at aspects in the network topology and user

A água residual tratada é uma fonte de água alternativa e a sua utilização contribui para a mitigação da escassez de água, através da aplicação da água para reutilização (ApR) em usos compatíveis, como rega de espaços verdes e lavagem de ruas. A modelação do decaimento de cloro em Sistemas de Distribuição de ApR (SDApR), englobando o decaimento de cloro no seio da água e o decaimento de parede, carece de estudos que proponham metodologias de implementação, bem como de trabalho experimental (laboratorial (e.g. testes de decaimento de cloro em ApR) e à escala real). Este artigo apresenta uma metodologia para modelação do decaimento de cloro em SDApR, tendo em conta a modelação hidráulica, o decaimento no seio da água e o decaimento devido à parede, que pretende servir de ferramenta de apoio à identificação das gamas de desinfetante a aplicar e a manter nas redes, contribuindo para promover uma adequada gestão e manutenção da desinfeção. As condições de operação do sistema, as características de qualidade da ApR e os requisitos de residual de cloro a manter na rede são condicionantes a considerar na modelação de um SDApR. Dados os níveis de amónia dos efluentes tratados em Portugal, deve ser dada especial atenção à seleção do desinfetante, propondo-se um residual de monocloramina.

Extending for more 900 km with diverse geomorphologies and land-use occupation, the Portuguese coastal zone is highly vulnerable to overtopping and flooding.

Water losses from water distribution means have a high environmental impact in termsof natural resource depletion (water, energy, ecosystems). This work aims to develop an opticalairborne surveillance service for the detection of water leaks (WADI

Assessing the Nature-Based Solutions (NBS) contribution to urban resilience, along with developing tools capable of demonstrating their long-term value, comprises a most needed step forward. Nevertheless, the NBS contribution to urban resilience has been yet slightly explored. Given the urban resilience complexity and multiple NBS capabilities, specific needs for a robust assessment should be investigated. This paper identifies the requirements for a comprehensive assessment of the NBS contribution to urban resilience and analyses the main assessment frameworks focused on resilience and NBS for urban drainage. First, the evolution of the resilience concept and relevant resilience assessment frameworks (RAF) are presented. Secondly, NBS challenges to enhance resilience and NBS assessment proposals are analysed. Thirdly, the attributes for assessing urban resilience and aspects to assess the NBS contribution are analysed. To conclude, a critical analysis of the assessment approaches is presented. Important challenges across the RAF have been identified, especially regarding their feasibility of application. Based on the performed analysis, most RAFs are not feasible for city benchmarking and assessing the resilience evolution over time, neither for assessing comprehensively the NBS contribution. Regarding specifically the NBS assessment proposals, just one focused on urban resilience was developed to date, which allows evaluating their contribution over time, between cities, or between different NBS.

Within the BlueSafePort project an Early Warning System (EWS) is being developed for forecasting and alerting emergency situations related to ship navigation in ports, as well as operational constraints. Port terminals downtime leads to large economic losses and largely affects the port

Early Warning Systems are crucial disaster-risk-reduction strategies as they allow local authorities to prepare and implement in advance the necessary measures to avoid major destruction and risk for individuals and properties caused by storm events. HIDRALERTA is a forecast, early warning and risk assessment system for port and coastal areas that usesforecasts of sea-waves and water levels to evaluate overtopping/flooding events and risks associated with mooring of ships.
