An explicit coupled two-dimensional (2D) hydromechanical model (HMM) that can simulate discontinuous features in the foundation, as well as the effects of grout curtains and drainage systems, is employed to evaluate the influence of key parameters such as dam height, foundation behaviour, joint patterns, joint stiffness and strength, hydraulic apertures, and grout curtain permeability. A parametric sensitive study using four gravity dams, and a real case study of an operating dam are presente...

This study bridges the existing gaps in quantifying risk and enhancing community defences by applying a cohesive five-pillar risk and resilience framework developed within the C2IMPRESS project. We assessed the anticipated impacts of various C2IMPRESS tools on community resilience across four European case study areas (CSAs): Egaleo (Greece), Mallorca (Spain), Ordu (Turkey), and the Centro Region (Portugal). Methodologically, a targeted survey asked CSA representatives to estimate the expecte...

The current paper primarily discusses the interconnection between water, energy and resilience, revisits the energy balance, proposes a modified calculation approach and metrics to assess system resilience criteria: energy efficiency and service flexibility. A sensitivity analysis is carried out considering: i) reference elevations, ii) levels of water losses, iii) contribution of shaft energy and pumping groups and iv) impact of water and energy efficiency improvement measures. The modified ...

Although urban resilience is a complex concept, several initiatives have made it more tangible. Urban public authorities and policymakers are of utmost importance, as they influence multiple neighbourhoods, stakeholders and aspects of urban resilience. Nevertheless, the role of individual facilities—such as sports fields—should not be overlooked. While their impacts are smaller in scale, they can significantly enhance local resilience and serve as inspirational pilots for broader initiatives....

Abstract Additive Manufacturing (AM), particularly Laser Powder Bed Fusion of Metals (PBF-LB/M), has become a key technology in the aeronautical industry to produce lightweight, high-performance components with complex geometries. However, the quality and reliability of AM parts remain critical concerns due to the potential formation of process-induced defects such as lack of fusion, keyhole, and gas porosity. Ensuring structural integrity requires robust, efficient, and non-destructive qual...

Managed aquifer recharge (MAR) provides a nature-based solution to water scarcity issues, contributing to the design of effective water management policies. The novelty of this study lies in the integration of multivariate statistical methods within the framework of multicriteria decision analysis to provide nonsubjective, semi-automatic estimations of MAR feasibility based on three thematic layers, particularly intrinsic (hydro-geological, topographical, meteorological) features, water avail...

Understanding the full potential of Nature-Based Solutions (NBS) is crucial in facing many societal and environmental challenges. The NATURELAB project promotes NBS for health and well-being and acknowledges the relevance of air quality within this context, which aligns with existing evidenceand EC directions. Air quality is key for enhancing urban population health and protecting vulnerable participants in Nature-Based Interventions (NBI), such as those with respiratory or cardiovascular con...

NATURELAB aims to promote paradigm shifts by integrating Nature-Based Solutions (NBS) and Nature-Based Therapies (NBT) into healthcare practices, including potential prescription by practitioners in the Portuguese National Health Service. As part of its outreach, NATURELAB participated in the Festival de Bem Estar, the largest Portuguese event on complementary therapies, which attracts a receptive and diverse audience. The project hosted a stand, staffed by trained members, where visitors cou...

O Programa de Investigação e o Programa de Pós-Graduação apresentados neste documento focam se na utilização das barreiras verticais de solo e bentonite como instrumento de prevenção e de mitigação da contaminação no subsolo e de controlo da intrusão salina em aquíferos costeiros. As consequências da degradação da qualidade do subsolo e das águas subterrâneas para a saúde pública, o ambiente e o desenvolvimento económico, e os custos da remediação dos terrenos baseados nas tecnologias do trat...

This report outlines the NATURELAB project’s strategic efforts to foster cross-fertilisation with other initiatives under the theme of Nature-Based Solutions (NBS), with a specific emphasis on enhancing health, well-being, and community resilience. As part of Work Package 5 - Communication, Dissemination & Exploitation, this deliverable highlights collaborations, synergies, and stakeholder awareness raising activities developed over the first 24 months of the project. NATURELAB aims to incre...

The accuracy of flood hazard mapping in dam-break modeling depends strongly on the quality of the Digital Elevation Model (DEM). This study evaluates six open-access global DEMs (SRTM, ALOS PALSAR, AW3D30, COPERNICUS, FABDEM, and ANADEM) in dam-break simulations for two Brazilian dams (Negreiros and Copiti), using HEC-RAS 2D and high-resolution LiDAR as reference. Four aspects were analyzed: (1) elevation accuracy; (2) flood wave propagation, including peak discharge and time-to-peak; (3) inu...

A desertificação e a seca estão a intensificar‑se e a tornar‑se mais frequentes, com impactos profundos nos sistemas agrícolas, ecológicos e socioeconómicos. O projeto IDD‑XB surge neste contexto, procurando integrar informação climática, agrícola e hidrológica proveniente de múltiplas fontes — observações in situ, satélite e reanálises — para melhorar a monitorização e previsão destes fenómenos e reforçar a resiliência das comunidades rurais. Sendo um projeto de “Estudos de Ciência para...

The NATURELAB project aims to enhance green and blue spaces, strenghtening climate resilience, biodiversity, and water management while promoting environmental, health and societal benefits for a sustainable future. The type and quality of green spaces strongly influences health and well-being of the users, which is significant for the case of nature-based interventions (NBI). NATURELAB developed a Framework of Key Indicators to address this therapeutic potential and assess diferent nature sp...

A barragem de Cahora Bassa, localizada no rio Zambeze, em Moçambique, é uma abóbada de dupla curvatura com uma altura máxima de 166 m. O fenómeno expansivo, devido a reações álcali-agregado, tem vindo a ser acompanhado desde que foi detetado há cerca de 40 anos. As estruturas salientes dos descarregadores de meio fundo são elementos em consola, em betão armado pré-esforçado, que servem de suporte às comportas. Qualquer alteração das suas dimensões (por exemplo dev...

A portfolio of key indicators and guidelines to characterise, design, protect, and manage different types of nature spaces is proposed by NATURELAB – Nature Based Interventions for Improving Health and Well-Being, a European project aiming to enhance the benefits of natural spaces for health and well-being.

Abstract - Investigating the long-term performance of building materials, such as drying shrinkage,moisture expansion, creep, and others, usually requires long-lasting tests with a high number of specimens. Given the initial costs, required data acquisition systems, and the time allocated, conventional sensors like LVDTs become costly for such long-term experimental studies. This article proposes an innovative cost-effective solution combining optical microscopy imaging, 3D printed sliding...
