I Congresso Infantojuvenil do Município de Gondomar - Livro de Resumos
Pinto, Dimas; Cunha, Telmo; Sofia, Aldina; Gonçalves, Inês; Dias, Luís; Ferreira, Marta; Pinto, Nuno; Santos, FernandoO Observatório do Desporto Infantojuvenil do Município de Gondomar tem como objetivo utilizar a investigação e a proximidade com a comunidade enquanto estratégias basilares para que existam experiências desportivas mais positivas. Não obstante, detetam-se diversos desafios na realidade atual. Presentemente, verifica-se que (a) apenas realizar ações de formação sobre o desenvolvimento de jovens é insuficiente pa...
A new and practical method to obtain grain size measurements in sandy shores based
Baptista, Paulo; Cunha, Telmo; Gama, Cristina; Bernardes, CristinaModern methods for the automated evaluation of sediment size in sandy shores relay on digital image processing algorithms as an alternative to time-consuming traditional sieving methodologies. However, the requirements necessary to guarantee that the considered image processing algorithm has a good grain identification success rate impose the need for dedicated hardware setups to capture the sand surface images...
A Precise and Efficient Methodology to Analyse the
Baptista, Paulo; Cunha, Telmo; Bernardes, Cristina; Gama, Cristina; Ferreira, Oscar; Dias, AlveirinhoThe shoreline change rate is one of the most significant parameters in analysing sandy shore behaviour with time. This parameter can be monitored by means of low- and high-resolution survey methods, depending on the objectives of the monitoring programme. Survey efficiency is also very important for achieving high resolution in both space and time. Another important aspect is the precision and significance of t...
New land-based method for surveying sandy shores
Baptista, Paulo; Cunha, Telmo; Matias, Ana; Gama, Cristina; Bernardes, Cristina; Ferreira, ÓscarThe INSHORE system (INtegrated System for High Operational REsolution in shore monitoring) is a land-base survey system designed and developed for the specific task of monitoring the evolution in time of sandy shores. This system was developed with two main objectives: (1) to produce highly accurate 3D coordinates of surface points (in the order of 0.02 to 0.03 m); and (2) to be extremely efficient in surveying...
METODOLOGIA INOVADORA PARA MONITORIZAÇÃO DA EROSÃO COSTEIRA
Baptista, Paulo; Cunha, Telmo; Bernardes, Cristina; Gama, CristinaO desenvolvimento de metodologias de monitorização inovadoras, aplicáveis a escalas espaciais da ordem das dezenas de quilómetros, que se caracterizem pela sua eficiência e precisão, a custos relativamente baixos, e que permitam: (i) quantificar volumes sedimentares, (ii) determinar valores de recuo de linha de costa, (iii) avaliar a morfologia da praia sub-aérea e (iv) determinar a granulometria de sedimentos,...
DEVELOPMENT OF LOW COST AND HIGH PRECISION PROTOTYPE SYSTEMS FOR MORPHOLOGICAL ...
Baptista, Paulo; Cunha, Telmo; Bernardes, Cristina; Gama, Cristina; Ferreira, ÓscarIn the scope of the INSHORE project (INtegrated System for High Operational REsolution in Shore Monitorisation), a low cost and high efficiency monitoring system is under development, being adequate for sandy shore surveying (from the foreshore to backshore), which integrates two prototype systems for morphological and sedimentary data survey. The first prototype system is a high resolution GPS based system inc...
