Distinct shoreline behaviour along storm‐dominated and geologically controlled ...
Kümmerer, Vincent; Ferreira, Óscar; Loureiro, CarlosContemporary shoreline change is driven by a complex combination of factors, and as such is often highly variable along the coast. While differences in beach morphology can explain some of the variability in shoreline change, the geological constraints imposed by coastal geology are often overlooked. This work examines the influence of foreshore configurations with varying degrees of non-dynamic geological cont...
Development of topo-bathymetric continuum profiles for coastal barriers with gl...
Fanti, Valeria; Loureiro, Carlos; Ferreira, ÓscarCoastal barriers are dynamic and vulnerable coastal environments exposed to storms and rising sea levels, requiring a thorough understanding of their physical and geomorphological characteristics. Despite this, high-resolution topo-bathymetric data are not openly available for most of the world's coastal areas, preventing accurate estimation of the exposure to storms and associated risks. Global models of topog...
Competências de investigação desenvolvidas pela pós-graduação: transferência pa...
Ferreira, Rogério; Mestre, Teresa Dionísio; Fernandes, Júlio Belo; Sousa, Luís; José, Helena; Fonseca, César; Ferreira, ÓscarObjetivo: Explorar o modo como as competências de investigação, desenvolvidas através da pós-graduação em enfermagem, transferem-se para a prática clínica. Método: estudo qualitativo, exploratório e descritivo, desenvolvido com base em um grupo focal em outubro de 2021, utilizando uma amostra intencional de oito enfermeiros pós-graduados de uma instituição de saúde da região do Baixo Alentejo, Portugal. Para a ...
Nursing Intervention to Prevent and Manage Delirium in Critically Ill Patients:...
Fernandes, Filipa; Santos, Mariana; Anacleto, Ana Margarida; Jerónimo, Cátia; Ferreira, Óscar; Baixinho, Cristina LavaredaDelirium is an acute neuropsychiatric syndrome of multifactorial etiology with a high incidence in people admitted to intensive care units. In addition to reversible impairment of cognitive processes, it may be associated with changes in thinking and perception. If, in the past, it was considered an expected complication of severe disease, nowadays, delirium is associated with a poor short-term and long-term pr...
Nursing Interventions for Client and Family Training in the Proper Use of Nonin...
Fernando, Jéssica Moura Gabirro; Marçal, Margarida Maria Gaio; Oliveira, Cleoneide; Pedreira, Larissa; Baixinho, Cristina Lavareda; Ferreira, ÓscarNoninvasive ventilation is an increasingly disseminated therapeutic option, which is explained by increases in the prevalence of chronic respiratory diseases, life expectancy, and the effectiveness of this type of respiratory support. This literature review observes that upon returning home after hospital discharge, there are difficulties in adhering to and maintaining this therapy. The aim of this study is to ...
Development of a Bayesian network-based early warning system for storm-driven c...
L. Garzon, Juan; Ferreira, Óscar; Plomaritis, T. A.; Zózimo, A. C.; Fortes, C. J. E. M.; Pinheiro, L. V.Coastal hazards such as flooding and erosion can cause large economic and human losses. Under this threat, early warning systems can be very cost-effective solutions for disaster preparation. The goal of this study was to develop, test, and implement an operational coastal erosion early warning system supported by a particular method of machine learning. Thus, the system combines Bayesian Networks, and state-of...
Unforeseen cascading effects of an inlet opening
Ferreira, ÓscarThe opening of the Cacela Inlet (southern Portugal) in 2010 led to unforeseen effects observed after 2017, including an extreme acceleration of the retreat of the inland lagoon margin from about 0.2 to 2 m/year. This was a consequence of the development of a large flood delta in an area of limited accommodation space, forcing the main tidal channel to move inland. The coastal retreat currently affects a flat sa...
Development of a Bayesian networks-based early warning system for wave-induced ...
Garzon, Juan L.; Ferreira, Óscar; Zózimo, A. C.; Fortes, C. J. E. M.; Ferreira, A. M.; Pinheiro, L. V.; Reis, M. T.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 le...
Storm identification for high-energy wave climates as a tool to improve long-te...
Kümmerer, Vincent; Ferreira, Óscar; Fanti, Valeria; Loureiro, C.Coastal storms can cause erosion and flooding of coastal areas, often accompanied by significant social-economic disruption. As such, storm characterisation is crucial for an improved understanding of storm impacts and thus for coastal management. However, storm definitions are commonly different between authors, and storm thresholds are often selected arbitrarily, with the statistical and meteorological indepe...
The effectiveness of elevated boardwalks in restoring coastal dunes
Ferreira, ÓscarCoastal dunes are important habitats that also play an important role in coastal protection. In areas of high tourist activity, they have often been degraded by trampling and intensive use, resulting in a loss of ecological, aesthetic and protective values. As a result, several management actions have been taken to minimise dune degradation and enhance their recovery. One of these measures is the installation o...
