As formas e depósitos glaciários, testemunhos de antigas glaciações, podem fornecer aos geomorfólogos importantes dados sobre a natureza dos processos que ocorrem em glaciares atuais. Com este artigo pretende-se caraterizar e apontar alguns elementos para a génese das moreias de idade plistocénica presentes no Vale Glaciário do Alto Vez no noroeste de Portugal, através da análise do till fabric e do estudo gran...
Este artigo descreve as fases iniciais do processo de governação do risco no concelho de Alvaiázere, iniciado com a interpretação do território, no conhecimento dos seus fatores de risco e do modo como os mesmos são percecionados. O modelo adotado consiste num processo integrado de governação do risco segundo o quadro proposto pelo International Risk Governance Council (IRGC, 2005, 2008), sendo que neste artigo...
This paper presents the results of a research on the perception of environmental risks in the Coast of the towns of Areia Branca (RN, Brazil) and Figueira da Foz (Center of Portugal). It was supported in the application of structured questionnaires in the populations of both towns, having been boarded about 100 people along the coastal communities of each one of the places. The results recorded some significant...
The main aim of this paper is to perform a modelling of social and environmental data that results in a vulnerability map of 17 countiesfrom theCentralRegion of Portugal. There are presented characterizations of the counties under study as subsidies for vulnerability analysis performed. The methodology adopted for the vulnerability analysis is based on factor analysis that aggregated social and environmental as...
As características basicamente mediterrânicas do clima de Portugal Continental fazem com que os riscos climáticos diretos sejam os mais significativos se tivermos em conta o impacto sobre a mortalidade da população ou o valor económico dos bens afetados. Com a presente apresentação pretende-se chamar a atenção para a importância deste tipo de riscos, para a metodologia da sua avaliação e cartografia, bem como r...
Glacier Horcones Inferior is a covered glacier, and a typical example of Andean mountain glaciers. Its study will allow us to understand glaciers’ dynamics through the Holocenic, by analysing its movement back and forth, as well as the geomorphological marks of that movement. Glaciers in the valley of Horcones Inferior have a typology quite different from most of the well-known glaciers, with a predominance of ...
In Portugal, floods are the most recurrent and dangerous natural phenomena and represent a hight risk for the Human Being, endangering the safety of people and property and cause socio-economic damages. With this work we intend to evaluate the susceptibility to flood risk in the municipality of Torres Novas (Portugal) through the combination of heuristic and quantitative multi-criteria (HEC-RAS) models, validat...
The coastal plain located between Figueira da Foz and Nazaré (western central Portugal) has a general low slope towards west, with altitudes below 200 m, and constitutes an important geomophological unit that is usually called “Littoral Platform”. At north, east and south, the platform is limited by the limestones relieves of the Serra da Boa Viagem – Verride arc, Sicó Massif and Estremenho Massif. These reliev...
The present study aims to know the hydrological dynamic of karst massif of Sicó (centre of Portugal). Furthermore, this paper demonstrates that time series analyses (correlation and spectral analysis) can contribute highly to understand the hydrodynamic behaviour of karst aquifers and deduce physical characteristics of the system (degree of karstification, storage capacity). The available data consists of 2 spr...
