SOPRO 3.0
SOPRO1.0, constituiu a primeira versão do pacote de informática desenvolvido no Laboratório Nacional de Engenharia Civil, para a caracterização da agitação marítima em zonas costeiras e de simulação da navegação no acesso ou no interior de zonas portuárias. É composto por um conjunto de bases de dados, uma interface com o utilizador e um conjunto de módulos de cálculo. A interface com o utilizador permite o armazenamento e manipulação de dados, a execução dos modelos de propagação da agitação marítima e de simulação da trajectória de navios, assim como a obtenção dos resultados e a criação das correspondentes visualizações gráficas. O pacote foi criado no sistema gestor de base de dados Microsoft Access

Study of mural paintings using in-situ XRF, confocal Synchrotron-?-XRF, ?-XRD, optical microscopy and SEM-EDS the case of the frescoes from Misericordia Church of Odemira
In this work, we present the results of an analytical method developed for detailed pigment identification, stratigraphy, and degradation of the paint layers of mural paintings applied in the study of the 17th century frescoes from the Misericordia Church of Odemira (Southwest Portugal). In situ X-ray fluorescence spectrometry analyses were performed on three panels of the mural paintings and complemented by colorimetric measurements. The different color areas were also sampled as microfragments (approx. 1 mm2)that were studied as taken or mounted in epoxy resin to expose the different paint layers. The microfragments of paint layers and their cross sections were characterized by optical microscopy and scanning electron microscopy coupled with energy dispersive X-ray spectrometry. Furthermore, elemental analysis was obtained with spatially resolved confocal synchrotron radiation micro-X-ray fluorescence spectrometry performed at ANKA synchrotron FLUO beamline. Occasionally, phase analysis by micro-X-ray diffraction was also performed. Results from the different techniques allowed pigment identification and, in some cases, the evaluation of color changes due to degradation processes and, considering the Southern Portugal geology, the identification of their possible provenance. The pigments used were essentially yellow, brown and red ochres, smalt blue, copper green, and black earths, probably from local sources.

Surf hydrodynamics in front of collapsing coastal dunes
The hydrodynamics of the surf zone in front of collapsing coastal dunes are examined. The data was gatheredduring the HYDRALAB-III funded Transnational Access experiment performed at the CIEM large-scale waveflume. Here, it is presented results of the cross-shore evolution of several flow parameters at four positions. Despikedand band-pass filtered ADV velocity data were used to enable a focus on only the short-wave component.As the waves approach the shore they reduce their (velocity) skewness, but increase their vertical asymmetry.Despite the non-negligible wave reflection, the theoretical wave model of Abreu et al. (2010) was applied tosuccessfully reproduce the measured velocities. Lastly, an estimate of the bed shear stress exerted by the shortwavecomponents is presented.

Using Components of the Mahalanobis Squared Norm of the Residuals Vector for Quality Control in Local Engineering Networks
ABSTRACT: Local engineering precision networks are currently used to monitor the displacements of large dams, with safety control purposes. These one, two or three-dimensional networks are local, be-cause they are tied to local reference frames, and they are precision networks, because they aim at millimetric, or even submillimetric, accuracy. The most important obstacles to such an accuracy are the instrumental and environmental systematic errors. The atmospheric refraction, which cau-ses curvature of the path of the electromagnetic waves and changes its propagation velocity, is the major source of systematic errors. Effective measurement quality control strategies are of utmost importance to guarantee the quality of the results (displacements). The paper presents a quality control strategy supported by random quadratic forms that result from the decomposition of the Mahalanobis squared norm of the residuals vector. The strategy is compared to the well known da-ta-snooping method with regard to the quality control and parameter estimation performances.

Waves, wind and tidal forcing on a sandpit morphodynamics
Due to the increasing demand of sand for construction and beach nourishment, offshore extraction is being considered as an alternative source. Long term morphological changes caused by such an extraction must bepredicted because they can affect the sediments budget and potentially promote coastal erosion. Numerical models are powerful tools that can help in the evaluation of environmental impacts induced by this activity.The objective of this study is to describe the morphodynamics in the area surrounding a sandpit through the use of the MORSYS2D modelling system. The sandpit under study is located offshore Vale do Lobo, an importantbeach and golf resort located on the Southern Portuguese coast. The numerical solutions of the mean flow and the wave height around the pit were obtained with MORSYS2D between March 28 and April 29, 2008 when two storm events with significant wave height (Hs) greater than 2.5 m occurred.The numerical results are analysed in terms of the sand fluxes and bathymetry changes induced by wind and tidal currents and wave orbital velocities. The results show the strong impact of storm events in the morphologic evolution of the pit and surrounding area. The value for Hs > 2.5m was also confirmed as determinant for thesediment dynamics.
