Determinação dos tempos de evacuação pedestre da população exposta a movimentos...
Melo, Raquel; Zêzere, José L.; Oliveira, Sérgio C.; Garcia, Ricardo A.C.; Oliveira, Sandra; Pereira, Susana; Piedade, Aldina; Santos, Pedro P.As regiões de montanha são áreas suscetíveis à ocorrência de movimentos de vertente com velocidades consideráveis. Neste contexto, o desenvolvimento urbano nestas áreas provoca um aumento da exposição da população, estruturas e infraestruturas a este tipo de perigo, o que frequentemente conduz a perdas de vidas e a graves impactos socioeconómicos. No presente trabalho, pretende-se identificar os edifícios em ri...
Application of dynamic modelling to identify buildings at risk and pedestrian t...
Melo, Raquel; Zêzere, José L.; Oliveira, Sérgio C.; Garcia, Ricardo A.C.; Oliveira, Sandra; Pereira, Susana; Piedade, Aldina; Santos, Pedro P.Debris flows are one of the most hazardous types of landslides in mountain regions. In the upper part of the Zêzere valley (Serra da Estrela, Portugal) several debris flows events occurred in the last 200 years, some of them causing loss of lives and material damages. In this work, a methodology for pedestrian evacuation modelling, in a debris flow hazard scenario, was implemented. A dynamic run-out model was u...

Melo, Raquel; Zêzere, José; Oliveira, Sérgio; Garcia, Ricardo; Oliveira, Sandra; Pereira, Susana; Piedade, Aldina; Santos, Pedro Pinto; van Asch, TheoDuring the last two centuries, several debris flow events occurred in the upper part of the Zêzere valley, which is located in the Estrela mountain, in Central Portugal. These events were responsible for material damage as well as for the loss of lives. Given the susceptibility of this area to the occurrence of debris flows, a methodology for pedestrian evacuation modelling was implemented, in order to identify...
Debris flow run-out simulation and analysis using a dynamic model
Melo, Raquel; van Asch, Theo; Zêzere, JoséOnly two months after a huge forest fire occurred in the upper part of a valley located in central Portugal, several debris flows were triggered by intense rainfall. The event caused infrastructural and economic damage, although no lives were lost. The present research aims to simulate the run-out of two debris flows that occurred during the event as well as to calculate via back-analysis the rheological parame...
