Peças cerâmicas fabricadas usando pó de granito com adição dos produtos da comb...
Pinheiro, Halisson de Souza; Nogueira, Ricardo Emílio Ferreira Quevedo; Xavier, Louise Caroline Peixoto; Lobo, Cândido Jorge de SousaThe technical feasibility of the use of granite residues as raw material in the manufacture of ceramic test specimens, with additions of the Coal Mineral Combustion (PCC's) products as a reforestation phase, was studied. The materials used were White Wing granite (RGAB) and Coal Combustion Products (PCC), in concentrations of 0% w / w, 5% w / w, 10% w / w, 15% w / P of PCCs. For a characterization of the raw ma...
Proposta de gestão integrada das águas urbanas como estratégia de promoção da s...
Silva, Samiria Maria Oliveira da; Souza Filho, Francisco de Assis de; Cid, Daniel Antônio Camelo; Aquino, Sandra Helena Silva deThe study proposes the use of integrated urban water-management models as a strategy to promote water security and drought preparedness. It was developed in two stages: assessment of water system’s vulnerability; proposition of the integrated urban water management model. In the first step, a flow network model was used to simulate the water system. In the second stage, the inductive method was applied after co...
Use of Machine Learning in Evaluation of DroughtPerception in Irrigated Agricul...
Xavier, Louise Caroline Peixoto; Silva, Samiria Maria Oliveira da; Carvalho, Taís Maria Nunes; Pontes Filho, João Dehon de AraújoThis study aimed to understand the perception of drought among farmers, in order to supportdecision-making in the water allocation process. This study was carried out in theTabuleiro de Russasirrigated perimeter, in northeast Brazil, over the drought period of 2012–2018. Two analyses wereconducted: (i) drought characterization, using the Standardized Precipitation Index (SPI) based ondrought duration and freque...
Análise de índices para monitoramento de seca na região hidrográfica do Vale do...
Carneiro, Brenda Lara Duarte Souza; Martins, Lenise Farias; Xavier, Louise Caroline Peixoto; Studart, Ticiana Marinho de CarvalhoDrought are a usual event associated with the climatic variability, that impact on the several water consumers sectors. The phenomenon quantification can provide valuable support in promoting early proactive risk warning actions. Thus, this work aims to compare the SPI, scPDSI and SPEI, for the region of the Jaguaribe hydrographic basin, in Ceará. A comparative analysis between the proposed indices allowed to i...
Avaliação da percepção às secas usando técnicas de aprendizagem de máquina
Xavier, Louise Caroline PeixotoDrought management gains emphasis on the scenario of irrigated agriculture, an activity of considerable water vulnerability. Thus, the present study proposes the understanding of drought perception of irrigants and the identification of adaptation strategies, in order to support decision making in the water allocation process. The study was carried out in the irrigated perimeter Tabuleiro de Russas, in the inte...
Avaliação da segurança hídrica em cidades: o caso de Fortaleza
Silva, Samiria Maria Oliveira da; Cid, Daniel Antônio Camelo; Souza Filho, Francisco de Assis de; Aquino, Sandra Helena Silva deThis article evaluates the quantitative water security in cities in order to promote the development of methods and practices of drought management. For this, it was divided in two steps: analysis of the vulnerabilities of the supply system and the discussion on the ways to promote water security. The vulnerability was analyzed by the failure frequency criteria of the demands and the accumulation of the reservo...
Influência do fluxo subterrâneo proveniente de bacia sedimentar na operação de ...
Leme, Rosiel Ferreira; Xavier, Louise Caroline Peixoto; Lima, Fabiola Costa de; Carneiro Neto, José Alves; Targino, Daniel Lira LopesThe geological characteristics of the contribution basin has significant influences over them, eventually occurring over all the operational period as a consequence of the subterranean flux, becoming evident in sedimentary basins and influencing the hydric balance directly. The objective of this paper is to evaluate the interference of the subterranean flux in the hydric reservation volume of a dam during the o...
