Inundações e galgamentos costeiros em Portugal continental: complexidade territ...
Tavares, Alexandre; Barros, José; Freire, PaulaRESUMO: Portugal Continental apresenta uma zona costeira extensa, diversificada e complexa. Essa diversidade dá origem a diversas características geológicas e geomorfológicas que suportam diferentes densidades de ocupação humana e uma variedade de atividades, de uso e de ocupação do solo. A crescente ocupação antrópica da zona costeira nas últimas sete décadas originou um conflito com a dinâmica natural dessas ...
The influence of rural fires in surface water quality
Sequeira, Mário; Dinis, Pedro; Lopes, Ana Maria Aguiar Castilho Ramos; Tavares, AlexandreABSTRACT: This study focuses on the impact of rural fires on water quality in the Mondego River basin in Portugal. An analysis of water quality was conducted to assess the interaction between fires, land use, geology, and precipitation. Data from a monitoring program conducted over two hydrological years were statistically analyzed and compared to a geochemical background. The results reveal substantial increas...
Influência da seca severa em indicadores de águas superficiais
Sequeira, Mário; Tavares, Alexandre; Lopes, Ana Maria Aguiar Castilho Ramos; Dinis, PedroRESUMO: Durante a seca que afetou Portugal no ano hidrológico de 2021/2022, foram realizadas cinco campanhas de monitorização das águas superficiais na bacia hidrográfica do Rio Mondego. A amostragem ocorreu de março a novembro de 2022 e os indicadores de qualidade da água medidos foram comparados com um fundo geoquímico criado a partir de dados abertos. Durante o período de seca, as águas superficiais parecem ...
Geosciences research mapping for Portugal in the year 2023: standing and future...
Tavares, Alexandre; Rocha, Fernando; Dinis, Pedro; Pereira, AlcidesABSTRACT: This study carries out a mapping of research topics in geosciences within the context of Portugal for the year 2023. The data for this analysis are sourced from 11 Research Centres and 4 other entities whose missions include research as their main objective. A bibliometric analysis is performed using the SCOPUS database for a sample of 103 researchers, with data collected in May 2023. A focus group is...
1926 – 2021 flood impacts in Mozambique from a local database incidence
Nganhane, Helio Vasco; Tavares, Alexandre; Santos, Pedro Pinto; Dgedge, GustavoABSTRACT: Due to its geographical location, Mozambique has been frequently affected by climatic events, in particular depressions, storms and tropical cyclones that often cause flooding processes. In the last 10 years, the frequency of these events has increased and consequently the social and economic losses have also been amplified. This work presents results from ongoing research to create a database, using ...
Tropical cyclone meteorological extreme events and their large impacts in Mozam...
Nganhane, Helio Vasco; Tavares, Alexandre; Santos, Pedro Pinto; Fernández Sánchez, AdriánABSTRACT: The monitoring and prediction of tropical cyclones in Mozambique rely on short databases that sometimes lead to inadequate interpretations due to the lack of precision in equipment and limited human resources. Misinterpretations are also related to the notoriously unstable climatic conditions in the oceanic domain, especially in the Mozambique Channel region, particularly in recent years. It is essent...
Insights from Africa-Europe Cooperation in Higher Education Institutions, Susta...
Pinto, Hugo; Vieira, Gabriela Cortês; Nogueira, Carla; Tavares, AlexandreCurrently, Higher Education Institutions (HEIs) are expected to play multiple roles, not just for knowledge production and training but also for regional development, innovation systems strengthening, and sustainability. Although these roles are crucial for territories, regions, and economies to be increasingly competitive, HEIs often face a set of constraints that do not allow them to develop all of these dime...
BeSafeSlide – A Landslide early warning soft technology prototype to improve co...
Oliveira, Sérgio C.; Zêzere, José L.; Trigo, Ricardo M.; Marques, Fernando; Tavares, Alexandre; Marques, Rui; Ramos, Alexandre M.; Melo, RaquelAs observed worldwide during the last decades, landslides are one of the deadliest natural hazards in mainland Portugal and Azores archipelago being responsible for significant direct and indirect societal and economic losses, justifying the implementation of a landslide early warning system at the regional scale. The BeSafeSlide project aims to develop and implement a soft technology/low-cost prototype for pre...
Vulnerabilidade territorial, distribuição, operacionalidade e eficiência de hid...
Antão, Daniel; Palrilha, Paulo; Tavares, Alexandre; Mota, RuiOs incêndios podem surgir de problemas estruturais, ou simplesmente de situações espontâneas, estando quase sempre relacionados com a ocupação antrópica. O ser humano foi desenvolvendo estratégias, técnicas de mitigação e resposta a estes eventos. Os hidrantes exteriores enquadram-se no processo de resposta à manifestação do risco de incêndio como um equipamento de segunda categoria, porque não se destinam ao a...
Assessment of buildings exposure and potential losses to landslides based on ce...
Oliveira, Sérgio; Melo, Raquel; Alves, Carlos; Rocha, Jorge; Garcia, Ricardo; Tavares, Alexandre; Zêzere, José; Pereira, Susana; Santos, Pedro PintoLandslides, like any natural hazardous process, do not generate risk until some type of interaction with human settlements or activities occur. Consequently, the landslide susceptibility assessment and the quantification of the exposure and potential losses of structures and infrastructures is crucial for informing emergency and spatial planning in areas prone to geomorphological hazards. Thus, the major aim of...
