Conservação e proteção da água subterrânea: uma revisão de metodologias de mape...
Peixoto, Filipe da Silva; Cavalcante, Itabaraci Nazareno; Araújo, Karen Vendramini de; Silveira, Renata Nayara Miranda CâmaraSustainable use of the water resource is a necessity for promote access to water for future generation. In Brazil, the stats and union, in some cases, are responsible for water resource management, while the municipality has been responsible for territorial ordering. For this, is necessary the auxiliary of aquifer vulnerability methodologies, since the strategic importance of water on socioeconomic development ...
Impactos causados ao Aquífero Dunas pela ausência de saneamento na Zona Costeir...
Araújo, Karen Vendramini de; Cavalcante, Itabaraci Nazareno; Oliveira, Rafael Mota de; Silva, Mariane Pinto da; Lima Neto, Inácio Ocinaí deBy the whole Brazilian coast can be observed densification of urban occupation. Many times without proper precautions in respect of waste produced by human activities, especially in the case of domestic sewage. The lack of sanitation associated to the increased occupation represents a risk for the quality of water resources. This study was developed in the east coastal area of Ceara state with the objective of ...
As águas subterrâneas na gestão dos recursos hídricos na bacia hidrográfica do ...
Peixoto, Filipe da Silva; Silveira, Renata Nayara Câmara Miranda; Cavalcante, Itabaraci Nazareno; Araújo, Diego Teixeira de; Oliveira, Rafael Mota deThe management of water resources should promote integration of actions between groundwater and surface water, if necessary, for this, the use of legal instruments to promote rational and strategic water management. The study sought to investigate the role of groundwater in the Management of Water Resources in River Basin Curu, on use and grant’s application, and the granted well’s distribution in function of t...

Peixoto, Filipe da Silva; Cavalcante, Itabaraci Nazareno; Silveira, Renata Nayara Camara Miranda; Beserra, Fábio Ricardo SilvaThe objective of this study was to investigate the sanitary situation of an urban sub-basin hydrografic at Fortaleza (CE), in relation to water supply (WS) and sanitary sewage (SS). A geocoded database was developed based on data from the 2010 Census (IBGE). The Geographic Information System (GIS) was used in the integration of discrete data and the census tracts, providing the spatial representations. The wate...
Classificação hidroquímica e contaminação por nitrato no aquífero livre Barreir...
Araújo, Paulo Pontes; Oliveira, Francisco de Assis; Cavalcante, Itabaraci Nazareno; Queiroz, Joaquim Carlos Barbosa; Carneiro, Bruno SantanaThe Capitão Pocinho river basin at the northeastern Pará constitutes one important area of orange production in Brazil, with use of herbicides and fertilizers in the management practice. This research analyzed the diffusion of nitrate ions and classified the occurrence of the most important ions. To collect the samples, 16 monitoring wells were dug in the citrus plantation in the Capitão Pocinho village. Water ...
Efeitos da seca em perímetros irrigados no semiárido brasileiro
Silveira, Renata Nayara Câmara Miranda; Peixoto, Filipe da Silva; Costa, Raimundo Nonato Távora; Cavalcante, Itabaraci NazarenoSetting up irrigated perimeters (IP) in the northeastern semi-arid of Brazil was an necessary attempt on development agricultural activities in a reality where water is the main limiting factor and the most problematic on account of the irregularities of the climate and droughts. This work aimed to measure the impact of the extensive drought of 2010 through 2015 on the production of 13 irrigated perimeters in t...
Mapeamento da vulnerabilidade e risco de poluição das águas subterrâneas na por...
Gomes, Maria da Conceição Rabelo; Mendonça, Luiz Alberto Ribeiro; Cavalcante, Itabaraci NazarenoThe present work presents the assessment of the vulnerability and risk of groundwater pollution in the eastern portion of the Araripe Sedimentary Basin, Ceará, Brasil, through the GOD and POSH methods. The GOD method presented three classes of vulnerability: low, moderate and high, with a predominance of moderate vulnerability (80%). The POSH method classified the pollutant loads into three indexes: high, moder...

Pedrosa, Adriana Albuquerque; Sales, Vanda Carneiro de Claudino; Cavalcante, Itabaraci Nazareno; Carvalho, Alexandre Medeiros deThis paper presents an analysis of geodynamic and morphogenesis of the dune field in the Canoa Quebrada region, located in the municipality of Aracati, inserted in the state of Ceará. It covers the area formed by fluvial-marine plain, the strip of beach and dune field located on the right bank of the mouth of the river Jaguaribe. The estimated period corresponds to the dynamic analysis of the dune field based o...
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 ...
Reservas hídricas subterrâneas e contribuição à gestão dos recursos hídricos em...
Silveira, Renata Nayara Câmara Miranda; Costa, Raimundo Nonato Távora; Peixoto, Filipe da Silva; Sousa, Humberto Gildo deGroundwater are strategic sources to improve water supply and to decrease water empty areas. Through the study of an Alluvial Aquifer stretch of the River Curu, we sought to characterize the groundwater reserves to aid in water management of this hydrogeological unit in semiarid regions. Monitoring of water table of 14 shallow wells was performed during the period of one year (May 2014 to May 2015), correspondi...
