Geomorfología post holocénica y riesgo ambiental: el vertedero de resíduos sóli...
Sabadia, José Antonio Beltrão; Duarte, Cynthia Romariz; Casas, AlbertPost Holocene geomorphology and environmental risk: the solid waste landfill of Jangurussu, Fortaleza, Ceará State, Brazil. In countries like Brazil, social and economic inequality leads to most of the population is more tolerant in front of existing serious environmental problems, and makes much of the public is subject to live near landfills municipal solid waste. Built rapidly in urban modeling, creating a n...
Avaliação da acurácia dos ortomosaicos e modelos digitais do terreno gerados pe...
Silva, Cristiano Alves da; Souto, Michael Vandesteen Silva; Duarte, Cynthia Romariz; Bicho, Cristina Prando; Sabadia, José Antonio BeltrãoThis present paper aims to demonstrate the evaluation of the accuracy of orthomosaics and Digital Terrain Models (DTM) generated by the Unmanned Aerial Vehicle (UAV) developed by the University of Brasilia (UnB) in partnership with the National Department of Mineral Production (DNPM). This study evaluated the orthomosaic and the MDT from a pile of laminated limestone exploitation tailings in the Santana do Cari...

Drone na auditoria ambiental: potencialidades e aplicações
Silva, Cristiano Alves da; Duarte, Cynthia Romariz; Sabadia, José Antonio Beltrão; Souto, Michael Vandesteen SilvaRemotely Aircrafts (RA), popularly known as Drones, are capable tools to generate highly accurate remote sensing products with a great potential perspective for use in the Environmental Audit process, performing previously exclusive tasks of manned aircrafts. However, because it is a relatively recent technology, it is justiied the need to consider the applicability of its use in environmental studies. The purp...
Short-time analysis of shoreline based on RapidEye satellite images in the term...
Duarte, Cynthia Romariz; Miranda, Fernando Pellon de; Landau, Luiz; Souto, Michael Vandesteen Silva; Sabadia, José Antonio BeltrãoCoastal environments are highly dynamic and sensitive to interference and variations caused by the numerous natural and anthropogenic agents. The northern coast of Northeastern Brazil has undergone intense erosion in recent years. However, the construction of the Pecém Port modified the beach and shoreline features differently from the adjacent areas. This article describes using remote-sensing images integrate...
Mapeamento de vulnerabilidade dos aquíferos dunas, barreiras e fissural na porç...
Moura, Pâmella; Sabadia, José Antonio Beltrão; Cavalcante, Itabaraci NazarenoThis work presents the natural vulnerability evaluation of the Dunes, Barreiras and Fissural aquifers from the northern Pecém Industrial and Harbor Complex, Ceará, Brazil, by using the DRASTIC and GOD methods. It aims to provide subsidies for environmental planning, in order to guide a management of the local groundwater. The mentioned methods use distinct parameters, being the DRASTIC more robust, restrictive ...
Sustentabilidade ambiental da extração de áridos: a lavra de areia no canal ati...
Nobre Filho, Pedro Aguiar; Sabadia, José Antonio Beltrão; Duarte, Cynthia Romariz; Magini, Christiano; Nogueira Neto, José de AraújoThis study analyzes the environmental sustainability of sand extraction along the active bed of Canindé river, Paramoti municipality, Ceará. The mined material was sampled, characterized and qualified for use as aggregate in construction. The deposit was cubed, resulting in measured reserves, indicated and total one. The sand extraction is carried out continuously in the active bed of the Canindé river, since t...
Principal component analysis and morphostructural characterization of a portion...
Duarte, Cynthia Romariz; Cordeiro, Elicius Feijó; Costa, José Higor Batista Araújo da; Sabadia, José Antonio Beltrão; Salgueiro, Ana RitaThis study used Landsat 5 Thematic Mapper (5-TM) images in the morphostructural characterization of the shallow continental shelf of the eastern coast of Ceará (CE), in the Jaguaribe river mouth. The dam built near the river mouth to transpose the water towards Fortaleza, CE, ensures good water transparency since little of the river-carried sediment reaches the sea. The used image was captured on date and time ...
Avaliação da acurácia do cálculo de volume de pilhas de rejeito utilizando VANT...
Silva, Cristiano Alves da; Duarte, Cynthia Romariz; Souto, Michael Vandesteen Silva; Santos, André Luis Silva dos; Amaro, Venerando EustaquioAmong the various technologies used for calculate the volume of materials in mining, the Unmanned Aerial Vehicle (UAV) and the Light Detecting And Ranging (LiDAR), appear as fast and accurate alternatives compared to traditional surveying techniques such as total station and Global Navigation Satellite System (GNSS). Using these new technologies, the aim of this study was to evaluate the accuracy in volume calc...
Análise socioambiental do entorno do Estuário do Rio Cocó - Fortaleza / Ceará
Freires, Eduardo Viana; Gomes, Daniel Dantas Moreira; Duarte, Cynthia Romariz; Sabadia, José Antonio Beltrão; Souto, Michael Vandesteen SilvaThe urban densification, which sued in the surroundings of the estuary of the Rio Cocó, favored by the huge population growth occurred in Fortaleza/CE/Brazil, in recent decades, involved in various negative impacts on site. In order to understand the environmental dynamics around the Poop River estuary, from the urban increment were conducted physical and human data collection in the area of interest through li...
