Laboratory experiments of wave propagation over rigid and flexible vegetation fields, with the same configurations, were conducted to understand the effect of vegetation flexibility on the drag coefficient (CD). The direct method and the least squares method (LSM), ...
A set of scale-model tests carried out to enlarge the range of wave steepness values analysed in run-up, overtopping and armour layer stability studies, focusing on oblique extreme wave conditions and on their effects on a gentler slope breakwater's trunk armour and roundhead, ...
The impact of wave energy farms in the shoreline wave climate
Portuguese pilot zone case study using Pelamis energy wave devices
This paper describes the study of the impact of energy absorption by wave farms on the nearshore wave climate and, in special, the influence of the incident wave conditions and the number and position of the wave farms, on the nearshore wave characteristics is studied and discuss

A methodology for the analysis of physical model scale effects on the simulation of wave propagation up to wave breaking
Preliminary physical model results
This paper describes the experiments performed at the National Laboratory for Civil Engineering (LNEC) aiming at simulating, in a flume, the wave propagation along a constant slope bottom that ends on a sea wall coastal defence structure, a common structure employed in the Portug

The influence of a set of wave farms for wave energy extraction on the nearshore wave climate at the pilot zone in Portugal was studied. Two different wave farms configurations (named B and C) and two representative wave conditions (winter and summer) were considered. Energy extr

FUNWAVE numerical model is particularly suited to model nonlinear wave phenomena in the nearshore coastal zone. However, due to its inherent limitations, no a priori values are known for the parameters to be used for a particular application of FUNWAVE. Hence every simulation pro

Internal wave generation on finite element model BOUSS1D_iw
Comparison with experimental data
This paper presents a description of a finite element numerical model, BOUSS1D_iw based upon the Boussinesq equation derived by Nwogu (1993). Special attention is given to the procedure implemented into this model for wave generation, by using a source function. In order to valid
