Resumo: This work proposes a Lagrangian modeling of the distribution of water saturation of the soil based on the theory of topographical similarity of complex terrain, highlighting hydrometeorological aspects. The distribution of the precipitated water on the ground is obtained as a consequence of the conservation of mass flow, considered the hydrological similarity along drainage tracks under different topographic slope, catchment and infiltration. The distributor model allows advances in computational optimization of both the saturation deficit and water table. The applicability is exemplified with a surface of a gentle hill and also applied to discuss hydrology of the plain found northward of the Metropolitan Area of Rio de Janeiro. It is shown that a spatial resolution smaller than 90 m should be used to consider the details of the problem. The results highlighted the role of complex topography, including the hydrology of floodplains and anthropogenic modifications of the surface (in the form of urban runoff channels and urbanization) for a more complete understanding of the hydrological distribution of the Metropolitan Area of Rio de Janeiro, RJ, Brazil.

A distribuição da água precipitada no terreno é obtida como uma consequência da conservação de massa do escoamento, considerada a similaridade hidrológica ao longo de faixas de drenagem, sob diferentes condições de inclinação topográfica, captação e infiltração. A aplicação desse tipo de modelo de distribuição hidrológica permite uma otimização computacional, tanto na estimativa do deficit de saturação do solo quanto na distribuição da profundidade do lençol freático. A aplicabilidade da proposição lagrangiana é exemplificada para um morro suave e também para discutir qualitativamente a hidrologia da Baixada Fluminense encontrada ao norte da Região Metropolitana do Rio de Janeiro (RMRJ), RJ, Brasil. Mostra-se que uma resolução espacial inferior a 90 m deve ser empregada para considerar os detalhes do problema. Os resultados destacaram o papel da topografia complexa, incluindo a hidrologia de planícies fluviais e as modificações antrópicas da superfície (na forma de canais de escoamento urbano e urbanização) para a compreensão da hidrometeorologia da RMRJ.Universidade Federal do Rio de Janeiro2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/782910.11137/2014_2_139_150Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 139-150Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 139-1501982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7829/6310Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKaram, Hugo Abi2017-02-15T17:28:22Zoai:www.revistas.ufrj.br:article/7829Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T17:28:22Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
