Variabilidade climática e ações antrópicas como impulsionadores da atividade eó...
Tudor, M.; Ramos Pereira, A.; Gaspar de Freitas, J.The building of dunes and sand drifts along the European coastline are generally related to climatic variability and sea-level fluctuation. The last phase of dunes formation in south-western Europe coincides with the Little Ice Age (LIA) period characterized by pronounced climate variability. Historical sources retrieved from archives also report sand-drift events along the Portuguese coast. The sand invaded ma...
Impacts of distinct spatial arrangements of impervious surfaces on runoff and s...
Ferreira, C. S.S.; Moruzzi, R. [UNESP]; Isidoro, J. M.G.P.; Tudor, M.; Vargas, M.; Ferreira, A. J.D.; de Lima, J. L.M.P.Made available in DSpace on 2020-12-12T01:42:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-12-01; Urbanization affects runoff processes and sediment transport, but the magnitude of the impacts remains poorly understood. Different spatial patterns of pervious and impervious surfaces influence flow and sediment connectivity between hillslopes and stream networks. Following years of research on the per...
Typology and distribution of small farms in Europe: towards a better picture. L...
Guimoar, Nuno; Godinho, Sérgio; Pinto-Correia, Teresa; Czejac, Marta; Kanya, J.; Maraccini, Elisa; Niedermayr, J.; O'Rourke, EllenThe contribution of small farms to local food supply, food security and food sovereignty is widely acknowledged at a global level. In the particular case of Europe, they often are seen as an alternative to large and specialised farms. Assessing the real role of small farms has been limited by a lack of information, as small farms are frequently omitted from agricultural censuses and national statistics. It is a...
Typology and distribution of small farms in Europe: towards a better picture
Guiomar, N; Godinho, S; Pinto Correia, T.; Czejak, M.; Kania, J.; Marraccini, E.; Niedermayr, J.; O’Rourke, E.; Ortiz-Miranda, D; Surová, D.The contribution of small farms to local food supply, food security and food sovereignty is widely acknowledged at a global level.

Ferreira, C. S. S.; Moruzzi, R.; Isidoro, Jorge M. G. P.; Tudor, M.; Vargas, M.; Ferreira, A. J. D.; de Lima, J. L. M. P.Urbanization affects runoff processes and sediment transport, but the magnitude of the impacts remains poorly understood. Different spatial patterns of pervious and impervious surfaces influence flow and sediment connectivity between hillslopes and stream networks. Following years of research on the peri-urbanizing Ribeira dos Covoes catchment in Portugal, this study uses laboratory rainfall simulation experime...
Insights of the AD 1755 Lisbon tsunami in the estuary of the Alcabrichel River ...
Tudor, M.; Ramos Pereira, A.; Costa, P.Studies on extreme marine inundations that affected the Portuguese coast refer mainly to the tsunami of AD 1775, considered the most devastating that affected the Portuguese coast. This work is focused on the recognition of a tsunami deposit in Alcabrichel River estuary and presents the analysis of a sediment core CF2. Lithostratigraphic, sedimentological, geochemical, morphoscopic and microtextural analyses re...
