Evaluating horizontal gradients in three-dimensional shallow water models that use bottom-following sigma coordinate can lead to large errors near steep bathymetry. A technique that has been proposed to minimize this problem ...

The characterisation of the dynamics of Figueira da Foz beach, in the West coast of Portugal, is presented based on the analysis of previous studies and results obtained from the application of a numerical model. Advances ...

Three alternative methods to remove oscillations in two-dimensional Eulerian-Lagrangian salt transport simulations are compared: a Flux-Corrected Transport (FCT) scheme, a non-linear filter (NLF) and the explicit introduction ...
Azevedo, A.; Silva, J. C.; New, A. L.(Deep-Sea Research Part I, 2006)
Internal solitary waves (ISWs), travelling towards the South South-West (SSW), are now well documented in the northern and central Bay of Biscay. These are formed from large-amplitude internal tides which result from the ...
An improvement on the simulation of outgoing waves on a time dependent numerical model for water wave propagation in the nearshore region is presented. The governing equations consist of a system of first order partial ...

Descreve-se um sistema de modelos para simular a evolução dos fundos de zonas costeiras sujeitas a maré, composto por um modelo hidrodinâmico de elementos finitos acoplado a um modelo de transporte de sedimentos de volumes ...
Oliveira, A.; Melo Baptista, A.(International Journal for Numerical Methods in Fluids, 1995)
Selected interpolation and integration finite element Eulerian-Lagrangian methods for the solution of the transport equation are systematically compared, through a combination of formal analysis and numerical experimentation. ...
