Renovação Das Águasno Complexo Estuarino Lagunar Mundaú-Manguaba(alagoas, Brasil)sob Diferentes Configurações De Embocaduras

Abstract: O presente trabalho analisa as alterações morfológicas ocorridas no Complexo Estuarino Lagunar Mundaú-Manguaba (CELMM), através de técnicas de geoprocessamento e da modelagem computacional. Inicialmente realizou-se uma análise multitemporal das variações das linhas de costa entre o período de 1986 até 2017 a partir de imagens dos satélites Landsat 5-TM e Landsat 8-OLI. As imagens foram vetorizadas em ambiente de Sistema de Informações Geográficas (SIG) para a posterior realização do cálculo das taxas de erosão… Show more

“…From there, these water masses moved progressively towards the communication channels, around the east margin. Through these results, the great relevance of the river discharges for the water renewal of the lagoons was clearly perceived, as pointed out by Lima (2017) and Pinheiro (2020). The results obtained corroborate the study by Pinheiro et al (2021), who observed, considering average conditions of river discharges from June to August (wet season), as well as different mouth configurations, that the west margin of the Mundaú L. was renewed faster than the opposite margin, with differences greater than 50 days; and that the northern region of the Manguaba L., in the eastern portion, presented the highest RT of this lagoon, reaching 90 days.…”
