Abstract:
The seminar addresses the key issues involved in simulating computationally the propagation of tsunamis in human-built environments such as urban waterfronts or ports. These are flows normally laden with debris possessing also an important geomorphic potential , as seen in the catastrophic events of Sumatra and Tohoku. A brief outline of the key features of a tsunami is followed by the description of a mathematical simulation tool developed to include eulerean and lagrangian physics of debris transport. Some numerical aspects are also addressed given the importance of conservativeness and robustness of wetting/drying front modelling. Some examples are shown, including tsunami propagation i) over mobile beds, ii) within highly resolved urban meshes and iii) within a commercial port
Short biography:
Dr Rui M.L. Ferreira is Assistant Professor at Instituto Superior Técnico, Universidade de Lisboa. His academic research includes experimental investigation of fluvial and estuarine processes, mostly involving turbulence and sediment transport, development of laboratory instrumentation and mathematical modelling of open-channel flows. Coordinates STAV project – a platform for modelling transient open-channel flows over mobile beds – and DIYPIV project – a non-commercial particle image velocimetry system. Has published more than 100 academic texts, including over 25 journal papers. Has supervised or currently supervises more than 25 researchers, including 6 PhD candidates. Is active in the organisation of scientific events and is a reviewer of journals in the fields of fluid mechanics, hydraulics and geophysics.
