A homage to the past aiming at the future
Rossi, Sergio; Cotovitz Junior, Luiz Carlos; Sousa, Paulo Henrique Gomes de Oliveira; Tavares, Tallita Cruz Lopes; Teixeira, Carlos Eduardo PeresAre the oceans dying? This is a question that many people are asking themselves more and more insistently. The answer is that in no case are they dying – but they are being transformed. Deeply. Unfortunately, this transformation has changed the ocean for a worst stage in terms of overall quality. Human-induced changes across the globe affect marine more than terrestrial ecosystems. And, at sea, there is a probl...
Editorial
Pinheiro, Lidriana de Souza; Sousa, Paulo Henrique Gomes de OliveiraA pressão humana nas zonas costeiras tem crescido exponencialmente nas últimas décadas devido aos usos derivados de diferentes atividades econômicas e sociais. A compreensão dos fatores que afetam a costa é essencial para fortalecer uma gestão sustentável e rigorosa desse tipo de espaço de fronteira entre a terra e o mar. Diversos grupos de trabalho se juntaram nesta edição especial para poder dar uma visão amp...
Wave energy distribution at inlet channel margins as a function of ebb tidal de...
Ambrósio, Bruna G.; Sousa, Paulo Henrique Gomes de Oliveira; Gagliardi, Marcelo H.; Siegle, EduardoWave energy gradients between and along the margins of inlet channels play an important role in defining the inlet margins’ evolutionary processes, mainly those related to spit erosion or accretion, and inlet migration. The aim of this study is to understand the wave power distribution along the margins of a tidal inlet (Cananéia inlet, São Paulo, Brazil), its variation over time, and the influences of the ebb ...
Classificação das variações morfodinâmicas e processos costeiros, praia do Paiv...
Holanda, Tiago Fernando de; Gonçalves, Rodrigo Mikosz; Lino, Anderson Pereira; Pereira, Pedro de Souza; Sousa, Paulo Henrique Gomes de OliveiraThe coastal zone related to the continental and oceanic portions, considered as dynamic and complex, undergoes changes at diff erent time scales. The morphodynamic classifi cations of beaches are essential for monitoring sedimentary cycles, identifying temporal processes of stability, accretion and erosion. The objectives of this study are to evaluate the morphodynamic classifi cation and the identifi cation of...
Fragmentação da paisagem na região metropolitana de Aracaju-SE, Brasil
Valenzuela, Gabriela Bispo; Gonçalves, Rodrigo Mikosz; Sousa, Paulo Henrique Gomes de Oliveira; Queiroz, Heithor Alexandre de AraújoThe present study aims to analyze the landscape fragmentation and its temporal evolutionconsidering an interval of 25 years (1990 and 2015), for themetropolitan regionof Aracaju, Sergipe,Brazil. The satellite images LANDSAT 5 and 8were used as materials. The images were classified using supervised method, according toseven land use/landcover classes, which are Forest, Mangrove, Sand-dune, Agriculture and/or Pas...
Espacialização da rede de efluentes despejada no rio Pacoti, trecho Redenção e ...
Brito, Antonio Patrick Meneses de; Santos, Ítalo Magno de Melo; Silva, Raquel Morais; Sousa, Paulo Henrique Gomes de OliveiraThe availability of potable water every day has been through an intense depreciation process, among the causes, we point out its contamination by effluent discharges. The work aims to identify the sewage discharge sites in Pacoti River by the central region of Redenção, CE. Thus, to analyze physicochemical parameters related to river water quality and how these parameters behave in the face of anthropic interfe...
Análise da vulnerabilidade à erosão costeira através de geoindicadores nas prai...
Menezes, Athos Farias; Pereira, Pedro de Sousa; Gonçãlves, Rodrigo Mikosz; Araújo, Tereza Cristina Medeiros de; Sousa, Paulo Henrique Gomes de OliveiraAs praias de Piedade e Paiva estão localizadas no litoral do Estado de Pernambuco e pertencem aos municípios de Jaboatão dos Guararapes e Cabo de Santo Agostinho respectivamente. O presente trabalho tem como objetivo avaliar a vulnerabilidade à erosão costeira analisando dez geoindicadores com características continentais e costeiras. Como materiais para extrair tais informações foram utilizadas imagens de saté...
Hidrodinâmica de um estuário tropical: rio Buranhém, Porto Seguro, Brasil
Silva, Ana Carolina Rodrigues de Sá; Bernardes, Marcos Eduardo Cordeiro; Assireu, Arcilan Trevenzoli; Siegle, EduardoEstuaries are dynamic environments that are highly vulnerable to anthropogenic influences, especially when adjacent to urban areas. In this study it is assessed for the first time the hydrodynamic characteristics of the Buranhém estuary (Northeast Brazil). The aim is to define the salt transport mechanisms and the hydrodynamics and stratification patterns of this tropical estuary, under both spring and neap tid...
Evolução da vulnerabilidade à erosão costeira na Praia de Massaguaçú (SP), Brasil
Ribeiro, Juliana dos Santos; Sousa, Paulo Henrique Gomes de Oliveira; Vieira, Danilo Rodrigues; Siegle, EduardoCoastal erosion can cause major environmental and social damage to coastal areas, and disorderly and inadequate human occupation at these sites can lead to erosion. Massaguaçú Beach, on the northern coast of São Paulo State, has suffered severe erosion in recent years. In the most severe cases, erosion had already begun to affect the road way Dr. Manuel Hyppolito Rego (SP-55) that runs next to the beach. Severa...
Environmental and anthropogenic indicators for coastal risk assessment at Massa...
Sousa, Paulo Henrique Gomes de Oliveira; Siegle, Eduardo; Tesseler, M. G.As a widespread trend, coastal erosion is occurring on many countries around the world. In general, such process is translated in environmental and socioeconomic damages in many coastal cities. The aim of this work is to use environmental and anthropogenic indicators to manage natural resources and subsidize regional planning. The study site is Massaguaçú Beach in Caraguatatuba, Northern Coast of São Paulo Stat...
