Araújo, M.A.V.C., Mazzolari, A. and Trigo-Teixeira, A., 2013. An object oriented mesh generator: application to flooding in the Douro estuary.This paper presents modification improvement of an existing 2D unstructured finite element generator, based on advancing front concept. The original version this generator (MESHGR) was developed Fortran language and, study, it is ported C improved terms robustness, efficiency speed. code uses classes describe each object. Besides generating mesh, also...

(eds.), Proceedings 13th International Coastal Symposium (Durban, South Africa), Journal Research, Special Issue No. 70, pp. 041–046, ISSN 0749-0208.The West Coast is facing severe erosion problems that threaten both population andthe immediate seaside properties. Some locations, such as Vagueira region, are...

The physical characteristics of sediments were measured from transects in the Minho, Lima, Cávado, and Ave estuaries northern part Portugal. variables investigated were: chemical composition, particle size, water content, salinity, temperature, pH. In a miniflume used to measure erodibility, erosion tests filmed with high speed camera rheological overlaying fluid layer using rheometer. Because sediment are related its erosion, characterization erodability correlated. influence season...

(eds.)In this study multi-criteria for 2D model is tested domain encompassing several spatial hydrodynamic scales, from the Western Atlantic Ocean shelf in front of Iberian Peninsula Lima River (Portugal) its estuary. For mesh design, series scalar criteria are identified known physical factors relevant...

The application of the acoustic Doppler velocimetry (ADV) technique to backward-facing step flows is very scarce in literature. This work aims at investigating applicability ADV over a step, various Reynolds numbers capture different flow regimes, and provide reliable data which can be used validate numerical models. Vectrino+ was laboratory flume customized code developed, implements methodology post-process records. normalized mean streamwise velocity turbulence profiles were compared with...

Globally, due to climate change and increased rates of coastal erosion, along with the need protect sensitive habitats, there is an increasing requirement for a sustainable approach which considers both effect marine environment on critical infrastructure impact that local environment. This paper presents methodology assessing structure longshore dynamics shoreline evolution by using external coupling phase-resolving ARTEMIS wave model model, UNIBEST. The can be applied at any location, but...

Maritime works deteriorate continuously and at a certain moment in time are need of some sort repair. Usually the decision maker seeks technical advice has to consider resources available. A literature review showed great limitations tools that today use. This paper presents implementation support methodology prioritize repairs rubble-mound breakwaters using MACBETH. Models for benefits repairing breakwaters, which based on visual inspection data only, were created, an expert meeting was...

Production of farmed fish is increasing worldwide and in areas which have traditionally not had large scale farming, specifically regions high sea temperature. This research presents a methodology to assess the impacts these developments on water quality manage them context other discharges into marine environment. Kuwait Bay, Kuwait, used as case study for types environments, where finfish farms are assessed regarding their location by implementing 3D coupled hydrodynamic–biogeochemical...

This paper reports an experimental assessment of various alternatives to construct artificial bed appropriate duplicate, in laboratory, the conditions relevant marine sediment erosion. The main goal study is find a simulated that approaches behavior natural sediments, based on velocity and turbulence profiles interface shear stress values. For purpose, experiments sediments collected two estuaries variety beds were carried out circular mini flume, 131 mm diameter. Velocity data taken by...
