“…Neste contexto, Cardoso et al (2006) destacam que a declividade e a cobertura vegetal são fatores importantes na tomada de decisão para o manejo adequado em bacias hidrográficas, visto que influenciam na precipitação efetiva, no escoamento superficial e no fluxo de água no solo. Segundo Felipe et al (2013) o conhecimento do relevo é de fundamental importância nas ações de planejamento e gestão na preservação futura. Para Rodrigues et al (2011), em áreas de maior declividade e desprotegidas de vegetação, ampliam-se as possibilidades de degradação da bacia hidrográfica.…”

“…Cardoso et al (2006) mensuraram Kf igual a 0,328 na bacia hidrográfica do rio Debossan, em Nova Friburgo-RJ. Já Felipe et al (2013) identificaram Kf igual 0,38, para a bacia hidrográfica do Ribeirão do Veado em Piratninga-SP, enquanto que Abud et al (2015), caracterizando quatro subbacias do município de Xapuri-AC, mensurou valores que variaram entre 0,11 e 0,27. Nos três estudos citados, os autores consideram a área de drenagem com baixa probabilidade de enchentes.…”

Este artigo tem como objetivo caracterizar e analisar a morfometria de dez sub-bacias hidrográficas (SBH) do baixo curso do rio Itapecuru, Maranhão, indicando as áreas prioritárias para implementação das ações de conservação e preservação do solo e dos recursos hídricos. Para tanto, foram calculados os parâmetros morfométricos das classes linear, zonal e hipsiométrica. Para a hierarquização e correlação de nove parâmetros morfométricos, foi utilizada a técnica denominada Weighted Sum Analysis (WSA). Foi constatado que as SBHs do Baixo Curso do rio Itapecuru são de pequena dimensão e na rede de drenagem predominam canais intermitentes e de primeira ordem. O escoamento dos canais fluviais apresenta baixa capacidade de transporte e, portanto, de erosão do canal fluvial, sugerindo que os mesmos são susceptíveis a processos de assoreamento, que são potencializados naqueles de menor ordem hierárquica de drenagem. Por outro lado, a baixa declividade das SBH pode atenuar o processo de erosão laminar de suas respectivas áreas de drenagem, uma vez que, o escoamento superficial será mais lento. Observou-se, ainda, que 83,3% da área estudada é zona de média e alta susceptibilidade ambiental, as quais devem ser priorizadas para implementação de ações de gerenciamento dos recursos naturais.

“…The altitude of the SBH varies from 126 m to 1197 m, with an average altitude of 477m. The mean slope was 3.5%, istic of the SBH studied, where the soft and undulating relief Felipe et al [38] reiterate that the relief is of fundamental importance in planning and management actions in the preservation of Hydrographic Basin. According to Ribeiro and Perreira [39], the absence of vegetation cover, the soil class, the intensity of rainfall associated to the greater slope, leads to a higher flow velocity, which in turn results in a smaller amount of water stored in the soil.…”

The relief forms, terrain differences, soil type and flora are the most important indicators for the description of a river basin or drainage network. The present work had as objectives, to perform the morphometric characterization of the hidrographic sub-basin (SBH) of the Espinharas river; analyze the intensity of land use; suggesting mitigating measures in areas with greater intensity of use, with the help of geospatial tools. The sub-basin of the Espinharas river, extends through thirty-one (31) municipalities, covering the states of Paraíba, Rio Grande do Norte and Pernambuco. For the analysis, images were used, from the Digital Elevation Model (DEM), Shuttle Radar Topographic Mission (SRTM), and Landsat 8 satellite images, resolution 30 m, bands 2, 3 and 4. Next, with QGIS software aid 2.18.17 generated the map of slope, mapping of intensity and land use, later calculations of the morphometric variables, and finally elaborated proposals of mitigating measures for the degradation of the sub-basin. The results of the morphometric parameters found for the Sub-basin indicate values of the Compass coefficient of 2.68 and Form factor 0.32, indicating that the sub-basin presents an irregular shape that differs from the figure of a circle, approaching an elongated shape, and thus not conducive to flooding. In relation to the intensity of use, the areas with low intensity class of use have the largest representation in this basin, covering an area of 2,147.98 km² (65.27%). The Espinharas river sub-basin presents several nonconformities of environmental impacts generated mainly by bad planning of use of the area and disrespect to the legislation. In this case, it is necessary for research to support effective public policies that favor less impacting agricultural practices, allowing farmers to provide their livelihoods at the same time, allowing future generations to survive in the semi-arid.

“…One of the steps for good planning in hydrology is obtaining information such as shape, relief, distribution and number of channels in watersheds (DA SILVA PEIXOTO et al, 2019). The mathematical study of these characteristics defines the morphometric analysis, in which it is possible to obtain indicators that relate to various processes within the catchment area, such as the form and the propensity to floods (ANDRADE et al, 2014;MOTTA et al, 2018), the drainage network and runoff and infiltration (FRAGA et al, 2014), and the relief and loss of soil by erosion (PEREIRA et al, 2015;SILVA et al, 2017). Several studies point out the importance of collecting morphometric information in watersheds (SANTOS et al, 2012;FELIPE et al, 2013;ABUD et al, 2015;LOPES et al, 2018;.…”

The spatial analysis of watersheds, as well as the evaluation off the changes occurring in their catchment area along the time are essential for the qualification of environmental changes. This study aims to characterize morphometrically the Pardo river watershed, as well as to evaluate the changes in soil use and occupation occurring between 2001 and 2016. The morphometric analysis consisted of the determination of the geometric parameters, relief information and drainage network using Geographic Information Systems. The land use and occupation information was collected through data from the online mapping platform of the Brazilian Mapping and Land Use Mapping (MapBiomas). According to the results, morphometry indicated that the watershed has low propensity to flood occurrence and tendency to conservation; great part of its area is between 600 and 1000 m of altitude, with predominance of undulating and soft-undulating slopes. The analysis of land use and occupation showed that the area devoted to agricultural activities increased during the period evaluated and occupies most of the basin, while the area of ??forests was reduced, the second in size, and these two classes occupy more than 96 % of catchment area.
