Caracterização Sedimentar Do Canal Do Estuário Do Rio Coreaú, Estado Do Ceará, Brasil

Abstract: O objetivo deste trabalho foi caracterizar a sedimentação longitudinal do estuário do Rio Coreaú, utilizando-se para isso metodologia cruzada de geoprocessamento e elaboração do Diagrama de Pejrup, para inferir o regime hidrodinâmico e sua repercussão na distribuição das facies sedimentares. Ficou evidente a ocorrência de um alto nível de hidrodinâmica devida à presença de sedimentos mais grossos em sua foz, e de moderado e alto níveis ao longo do curso do rio, dependendo de uma combinação entre variação sedim… Show more

“…Regarding studies and research associated with bathymetry, they can be applied in estuary channels, as observed in the Coreaú River, Ceará, for investigations on land use and occupation over decades (Colares, 2015). This approach is also useful in hydrodynamic studies in reservoirs, allowing estimates of flow velocity, residence time, and water column renewal rates, as demonstrated in Redenção, Ceará (França, 2021).…”

“…Contrasting to species that are relatively abundant in fishery captures ( e.g ., Hypanus guttatus and H. americanus ), S. schmardae was not recorded in several studies conducted in the area between the previous southernmost confirmed records (Pará State) and the one reported in the present study (easternmost Ceará State; see Figure 1). This area comprises estuaries, other sandy or muddy bottoms, and reef environments located on the coastlines of the Brazilian States of Pará (Barthem, 1985; Camargo & Isaac, 2001; Freitas et al ., 2019b; Pinheiro & Frédou, 2004; Rodrigues‐Filho et al ., 2020; Santo et al ., 2005; Silva et al ., 2016), Maranhão (Almeida et al ., 2011; Aragão et al ., 2019; Guimarães‐Costa et al ., 2019; Lessa, 1986; Martins‐Juras et al ., 1987; Nunes et al ., 2005, 2011; Rocha & Rosa, 2001; Silva et al ., 2018), Piauí (Aragão et al ., 2019; Guimarães‐Costa et al ., 2019; Mai et al ., 2012; Melo et al ., 2016) and Ceará (Araújo et al ., 2000; Basílio et al ., 2008; Freitas et al ., 2019a; Freitas & Lotufo, 2015). This indicates how uncommon or rare this species is in this region.…”

“…The river discharge is intermittent and concentrated to the rainy season and is subjected to interference from a dam 35 km upstream of the mouth. The average discharge value during the peak of the rain season (March to April) is 30 m 3 s -1 and less than 1 m 3 s -1 during the peak of the dry season (September to November) (Colares et al, 2016) The main goal of this paper is to characterize salt distribution along the Coreaú River estuary, considering different atmospheric water balance and discharge conditions.…”
