2DH modelling and mapping of surfbeat-driven flooding in the shadow of a jettied tidal inlet

Nahon, A.; Fortunato, A. B.; Oliveira , F.; Azevedo, A.; Henriques, M.; Silva, P. A.; Baptista, P.; Freire, P. (Elsevier B.V., 2023-05)

Near estuaries and harbours, submerged shoals and defence structures impact the exposure to overtopping. These features may be accounted for in two-dimensional horizontal (2DH) numerical models, either based on phase ...
A. Water Quality of a Reservoir in the Portuguese Tejo Basin

Cardoso da Silva, M.; Quadrado, M. F.; Carmona-Rodrigues, A. (J. European Water Pollution Control, 1994)

Accuracy of Sediment Flux Computations in Tidally Driven Simulations

Fortunato, A. B. (Journal of Waterway, Port, Coastal, and Ocean Engineering, 2007-09)
Adaptative grid techniques for baroclinic tidal models

Fortunato, A. B.; Oliveira, A. (******, 1998)

This paper describes the implementation and testing of three adaptive grid techniques for the vertical structure of shallow water models. The techniques are based on an r-method in which the nodes are moved vertically based ...
Aeolian microtextures in silica spheres induced in a wind tunnel experiment: Comparison with aeolian quartz

Costa, P.; Andrade, C.; Mahaney, W.; Marques da Silva, F.; Freire, P.; Freitas, M. C.; Janardo, C.; Oliveira, M.Alexandra; Silva, A.; Lopes, V. (Elsevier, 2013-01)

Microtextures in quartz attributed to aeolian transport, principally bulbous edges and abrasion fatigue have seldom been tested in the laboratory under controlled conditions. A wind tunnel experiment was conducted, using ...
Alerta precoce da contaminação fecal para o estuário do Tejo: implementação preliminar do modelo hidrodinâmico e de contaminação fecal

Costa, R.; Rodrigues, M.; Oliveira, A.; Fortunato, A. B.; David, L. M. (2012-06)

Resumo: Este trabalho apresenta os primeiros desenvolvimentos dum sistema de alerta precoce para situações de risco de contaminação fecal, que integrará uma plataforma de previsão em temporeal (RDFSPT, http://ariel.lnec.pt), ...
Alguns Aspectos da Engenharia Portuária e Costeira em Portugal

Fortes, C. J. E. M.; Santos, J. A.; Clímaco, M.; Mota Oliveira, I. (******, 2006)

An adaptive grid technique for the vertical structure of hydrodynamic models

Fortunato, A. B.; Oliveira, A. (Applied Mathematical Modelling, 1999)

The efficient resolution of the boundary layers occurring in geophysical flows has motivated the search for criteria to optimize the vertical nodal placement in three-dimensional shallow water models. This paper describes ...
An Approximate Sediment Budget for the Tagus Estuary. 3rd International SedNet Conference: The future of sediment management in Europe

Portela, L. I. (******, 2004)

An efficient computational model for water wave propagation in coastal regions

Oliveira, F. S. B. F.; Anastasiou, K. (Applied Ocean Research, 1998)

An efficient numerical model of the mild-slope equation, describing water wave propagation (combined refraction-diffraction), based on robust iterative methods is presented. The elliptic formulation (boundary value problem) ...
An Integrated Approach for Flood Risk Assessment in Estuaries

Freire, P.; Tavares, A.; Fortunato, A. B.; Oliveira, A.; Cardoso, M. A.; Pires, P. (2014-06)

Abstract: Floods in estuaries are associated to different hazard sources, such as high tide levels, storm surges and large fresh water discharges. In adjacent urban areas, the impact of estuarine high water levels is often ...
An oil risk management system based on high-resolution hazard and vulnerability calculations

Azevedo, A.; Fortunato, A. B.; Epifânio, B.; Boer, S.; Oliveira, E.; Alves , F.; Jesus, G.; Gomes, J. L.; Oliveira, A. (Elsevier, 2017-02)

A new oil risk management system is proposed herein. Risk is computed in a quantitative way, combining a detailed hazard maps generated with a process-based oil spill model over an unstructured computational grid, and a ...
An urban hypertrophic coastal system: Rodrigo de Freitas Lagoon, R. J. Brazil

Cardoso da Silva, M. (Multiple Dimensionds of global environmental change, 2006)

******
Analysis of cohesive sediment transport in decelerating and accelerating flow

Portela, L. I.; Reis, M. M. (******, 2005)

Analysis of S. João da Caparica beach vulnerability to a maritime storm event

Oliveira , F.; Fortunato, A. B.; Freire, P. (Instituto Hidrográfico, 2020-11)

The morphological response of the S. João da Caparica beach, Almada, to the maritime storm Hercules that occurred in January/2014, was studied through mathematical modelling, for three of twelve topo-bathymetric ...
Analysis of the stratification in the Guadiana estuary, Estuarine and Coastal Modeling VIII

Pinto, L.; Oliveira, A.; Fortunato, A. B.; Melo Baptista, A. (ASCE, 2003)

Analytical approximate wave form for asymmetric waves

Abreu, T.; Silva, P. A.; Sancho, F. E.; Temperville, A. (2010-03-19)

A simple analytical formulation that reproduces a skewed, nonlinear near-bed wave orbital velocity is presented. It contains four free parameters, where two are solely related to the velocity and acceleration skewnesses. ...
Análise da Contaminação Fecal por Águas Residuais em Zonas Costeiras. A nova Directiva das Águas Balneares

Rodrigues, M.; Oliveira, A.; Fortunato, A. B.; David, L. M. (******, 2006)

Análise da vulnerabilidade de uma praia estuarina à inundação

Vargas, C. I. C.; Oliveira, F. S. B. F.; Oliveira, A.; Charneca, N. (2008)

A ocorrência de condições hidrodinâmicas extremas em zonas ribeirinhas de estuários e lagunas, ambientes privilegiados para a ocupação humana, pode conduzir a avultados prejuízos materiais e humanos. Revela-se prioritário ...
