Resumo: The application of regionalization methods is one of the most important procedures for the estimation of the streamflow discharge in ungauged rivers catchments and its automation can reduce both processing time and susceptibility to errors. The Environmental Systems Research Institute (ESRI), in cooperation with the Center for Research in Water Resources at University of Texas (CRWR), has developed the ArcHydro toolset, a geospatial data model designed for hydrological models and used to accumulate attributes in the hydrographical net, among other functionalities. The present paper addresses the automation of the low flow index Q95 accumulation in the Doce River Basin by ArcHydro and the application of the regionalization method based on the proportionality of the ratio discharge per unit of drainage area. The effects of the reservoirs operation on water availability were computed automatically in this process and reliable results time savings were achieves.

A ESRI, em cooperação com a CRWR, desenvolveu o módulo ArcHydro que é um modelo geoespacial projetado para modelos hidrológicos que permite, dentre outras funcionalidades, acumular atributos ao longo da hidrografia. O presente trabalho demonstrou a automatização da acumulação da disponibilidade hídrica na bacia do rio Doce por meio do módulo ArcHydro utilizando o método de regionalização baseado na proporcionalidade da vazão específica. Os efeitos da regularização dos reservatórios presentes na bacia foram computados nesse cálculo de forma automatizada. O processamento se mostrou eficiente, oferecendo resultados confiáveis com economia de tempo.Universidade Federal do Rio de Janeiro2016-05-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/698410.11137/2015_2_47_55Anuário do Instituto de Geociências; Vol 38, No 2 (2015); 47-55Anuário do Instituto de Geociências; Vol 38, No 2 (2015); 47-551982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJenghttps://revistas.ufrj.br/index.php/aigeo/article/view/6984/5551Copyright (c) 2016 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBielenki Júnior, CláudioSouza, Fernanda Abreu Oliveira deMauad, Frederico Fábio2017-01-23T22:46:08Zoai:www.revistas.ufrj.br:article/6984Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T22:46:08Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
