Resumo: The morphometric characterization in river basins allows evaluating the behavior of these areas, providing important data for planning and preservation of natural resources. The present study aimed to characterize the morphology of the watershed of stream Santa Flora, City of Dracena - SP. It lies between the following UTM coordinates: 7604000m 7614000m the N and 432000m to 444000m E, with an area of 3465.55ha. The results showed a watershed 3rd order branching channels and low drainage density (0.83 km/km2). The conformation index (0.28), form factor (0.33) and the coefficient of compactness (1.30), indicate elongated shape. The sinuosity index of 1.10 indicates a tendency to rectilinear channels and extent of surface runoff route of 602.41m. The average slope is 4.5%, ranking as gently undulating relief. Dimensional parameters along with the standard drainage network morphometric indices of shape, relief, composition and allowed to infer that the area has low susceptibility to flooding and erosion risks.

O presente estudo teve como objetivo caracterizar a morfometria do córrego Santa Flora, município de Dracena – SP. Encontra-se entre as seguintes coordenadas UTM: 7604000m a 7614000m N e 432000m a 444000m E, com uma área de 3465,55ha. Os resultados apresentaram uma microbacia de 3a ordem de ramificação de canais e baixa densidade de drenagem (0,83km/km2). O índice de conformação (0,28), fator de forma (0,33) e o coeficiente de compacidade (1,30), indicam formato alongado. O índice de sinuosidade de 1,10 indica tendência a canais retilíneos e extensão do percurso superficial da enxurrada de 602,41m. A declividade média é de 4,5%, classificando o relevo como suave ondulado. Os parâmetros dimensionais juntamente com os índices morfométricos da forma, relevo, de composição e padrão da rede de drenagem permitiram inferir que a área apresenta baixa susceptibilidade a enchentes e riscos de erosões.Universidade Estadual de Londrina2016-08-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/1939110.5433/2447-1747.2016v25n1p05GEOGRAFIA (Londrina); v. 25 n. 1 (2016); 05-222447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/19391/19324Copyright (c) 2016 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessNardini, Rafael CaloreGomes, Luciano NardiniCampos, SérgioSilveira, Gabriel Rondina2022-09-21T12:38:03Zoai:ojs.pkp.sfu.ca:article/19391Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-21T12:38:03Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
