Wave directional measurement in Patos Lagoon, RS, Brazil

Abstract: The wave climate characterization in coastal environments is essentially important to oceanography and coastal engineering professionals regarding coastal protection works. Thus, this study aims to determine the most frequent wave parameters (significant wave height, peak period and peak direction) in Patos Lagoon during the period of operation of a directional waverider buoy (from 01/27/2015 to 06/30/2015). The equipment was moored at approximately 14 km from the São Lourenço do Sul coast at the geographic co… Show more

“…The results showed that waves with heights up to 0.30 m represent 77.9 % of the data at point 1, 71.3 % at point 2, 69.7 % at point 3, 68.2 % at point 4 and 65.7 % at point 5. Such a feature was also identified in Lemke et al (2017), making explicit the increase in larger waves with increasing depth. Seibt et al (2013) measured waves on Lake Uberlingen at a depth of 2 m and found that 93 % of waves were less than 0.15 m. The characteristics of this lake imply a smaller wind fetch than Patos Lagoon, thus reducing wave height.…”

“…Specifically, in Patos Lagoon, some studies such as those of, Lemke et al (2017)and Lemke et al (2018) can be cited. Despite some recent studies published in Patos Lagoon, according to Fontoura et al (2015), until 2015, there were no records of detailed studies on the wave regime in Patos Lagoon, and studies in this area are scarce.…”

“…Dados de ondas de janeiro a junho de 2015 obtidos pelo ondógrafo direcional Waverider (pertencente à FURG por meio do projeto Rede Ondas), fundeado no ponto de coordenadas 412.749,08 m E e 6.516.280,54 m N, UTM 22S (Fig. 1C), local onde a profundidade é cerca de 6 m, correspondem às maiores frequências de Hs de até 0,3 m (41,2%) e de 0,3 m a 0,6 m (38%), Tp de 2,5 s a 3 s (25,6%) e de 3 s a 3,5 s (22,1%) e direção de pico (Dp) de E (33,3%) (Lemke et al, 2017a). Dados de ondas de agosto a dezembro de 2018 obtidos pelo segundo ondógrafo direcional adquirido pela FURG por meio do projeto Rede Ondas, fundeado no mesmo local, correspondem às maiores frequências de Hs de até 0,3 m (43,7%) e de 0,3 m a 0,6 m (36,6%), Tp de 3 s a 4 s (41%) e de 2 s a 3 s (37,9%) e Dp de ENE (Marinho et al, 2020).…”

“…Such datasets are extracted, reanalyzed, and used as input for local models, whose results are often compared with data from moored instruments for a shorter period of time to validate them (for example in wave energy studies around islands conducted by Stopa et al, 2013Stopa et al, , 2011. There are also those who use long data series extracted from monitoring systems for wave quantification and propagation to the coast with local models (e.g., Lemke et al, 2017;Ludka et al, 2019), even though, in general, it is more difficult to obtain long time series of measured data, as a consequence of the high costs and difficulties of keeping moored instruments in coastal areas for long periods.…”
