Resumo: The present study aimed to analyze the influence of urban expansion combined with morphometric characteristics in flood occurrences, in the municipality of João Monlevade-MG. To measure and classify the morphometric characteristics and obtain a map of use and occupation within the basin, a database available on the Water National Agency (ANA) website and the Alos Palsar satellite images were used. Land use and occupation was divided into 6 classes. The vegetation area presented the highest percentage of the basin. For the basin morphometric characterization, using the ArcGis 10.3 software,  it was necessary to quantify the area, perimeters, length of the basin main channel and its vector lengths. With these data, the compactness coefficient (Kc), form factor (Kf), circularity index (Ic), slope indexes, Sinuosity index (Is), Altimetric amplitude (Hm), drainage density (Dd), channel hierarchy, total number of water channels in the basin and relief ratio (Rr) were calculated. The results showed that the Carneirinhoscreek watershed has an average natural susceptibility to the development of floods. However, through the analysis of land use and occupation, anthropic uses prevailed and  an increase of the urban expansion was noted. This tends to intensify flooding processes in the area.

Para medir y classificar las características morfométricas y obtener el mapa de uso y ocupación de la cuenca, se ha utilizado una base de datos disponible en el sitio de la Agencia Nacional del Agua (ANA) e imágenes del satélite Alos Palsar. El uso de la tierra y La ocupación se dividió en 6 clases. El área de vegetación fue la de mayor porcentaje de la cuenca. Para la caracterización morfométrica de la cuenca, utilizando el software ArcGis 10.3, fue necessário cuantificar el área, los perímetros, la longitude del canal principal de la cuenca y su longitud vectorial. Com estos datos se calcularon el coeficiente de compacidad (Kc), el factor de forma (Kf), el índice de circularidad (Ic), el índice de pendiente, el índice de sinuosidad (Is), la amplitude altimétrica (Hm), la densidad de drenaje (Dd), la jerarquía de canales, el número total de canales de agua em lacuenca y la relación de alivio (Rr). Los resultados mostraron que la cuenca del arroyo Carneirinhos tiene una susceptibilidad natural promedio a las inundaciones. Sin embargo, a través del análisis del uso y ocupación de la tierra se encontró que prevalecían los usos antropogénicos y se observo un aumento em la expansión urbana, hecho que tiende a intensificar los procesos de inundación em la zona.O presente estudo teve como objetivo analisar a influência da expansão urbana aliada às características morfométricas nas ocorrências de inundações, no município de João Monlevade-MG. Para a mensuração e classificação das características morfométricas e a obtenção do mapa de uso e ocupação dentro da bacia foram utilizadas uma base de dados disponível no site da Agência Nacional de Águas (ANA) e imagens do satélite Alos Palsar. O uso e ocupação do solo foi dividido em 6 classes. A área de vegetação foi a queapresentoumaior porcentagem na bacia. Para a caracterização morfométrica da bacia, utilizando o software ArcGis 10.3, foi necessário a quantificação da área, perímetros, comprimento do canal principal da bacia e seu comprimento vetorial . De posse destes dados, calculou-se o coeficiente de compacidade (Kc), fator de forma (Kf), índice de circularidade (Ic), índices de declividade, índice de sinuosidade (Is), amplitude altimétrica (Hm), densidade de drenagem (Dd), hierarquia dos canais, número total de canais d’água na bacia e relação relevo (Rr). Diante dos resultados obtidos foi possível constatar que a bacia hidrográfica do córrego Carneirinhos possui uma suscetibilidade natural média ao desenvolvimento de inundações. Contudo, por meio da análise do uso e ocupação do solo foi constatado que os usos antrópicos prevaleceram e  um aumento da expansão urbana foi observado, fato que tende a intensificar os processos de inundação na área.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/210110.33448/rsd-v9i2.2101Research, Society and Development; Vol. 9 No. 2; e136922101Research, Society and Development; Vol. 9 Núm. 2; e136922101Research, Society and Development; v. 9 n. 2; e1369221012525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2101/1776Copyright (c) 2020 Josiano Josiel Rodrigues Silva, Gisely de Assis Oliveira, Eliane Maria Vieira, Ana Carolina Vasques Freitasinfo:eu-repo/semantics/openAccessSilva, Josiano Josiel RodriguesOliveira, Gisely de AssisVieira, Eliane MariaFreitas, Ana Carolina Vasques2020-08-20T18:08:48Zoai:ojs.pkp.sfu.ca:article/2101Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:52.562351Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
