“…In a study made by Kudnar and Rajasekhar (2020) However, a similar result of RC was obtained by Odiji et al (2021) in Benue River, Cameroon, with a value of 0.048. According to the authors, low values of RC can be associated with highly permeable and homogeneous soil.…”

“…According to Tucci (2012), the water basin is key to understanding the hydrological cycle, mainly in its land phase, where it is possible to understand its relationship with other natural and anthropic factors. Thus, the watershed is the foundation of several environment analyses, such as morphometric characterization, as it says Kudnar and Rajasekhar (2020) which describes the morphometry as a tool that supplies a quantitative description of the drainage system from watershed.…”

“…According to several authors (Pinto et al, 2018;Venkatesh et al, 2019;Mahala, 2020;Kudnar and Rajasekhar, 2020;Odiji et al, 2021), the importance of the morphometric characterization of water basins stands out in the development of environmental studies, improvement of management plans of natural resources and conservative uses, besides mitigation of environmental impacts caused by atypical natural events. Still according to the same authors, this characterization allows identifying characteristics related to the shape, structural arrangement and drainage network, through linear, aerial and basin parameters, which gives subsidies to a precise analyze of physical aspects of the water basin.…”

“…The geotechnology use has been showed as a promissory alternative in environmental monitoring of water basins, acting as a major optimizing tool. The use of the Digital Elevation Model (DEM) through the remote sensing data of Shuttle Radar Topography Mission (SRTM) shows many advantages in digital resource applications such as processing speed, secondary data integration, replicability and less need for manual intervention, which is reflected by its several use by literature (Venkatesh et al, 2019;Kudnar and Rajasekhar, 2020;Odiji et al, 2021). These advantages are capable of providing products such as basin and drainage network delimitation, declivity, hypsometry and stream direction, which are essential in morphometric characterization of water basins (Valeriano et al, 2006;Oliveira et al, 2010).…”

Atualmente a Amazônia vem sofrendo significativos impactos provenientes de ações antrópicas como a ocupação rural e urbana desordenada, a agropecuária e a mineração. Frente a isso, a Política Nacional de Recursos Hídricos, instituída pela lei nº 9.433 de 8 de janeiro de 1997, apresenta o sistema de administração espacial denominado bacias hidrográficas. Dentre suas aplicabilidades, a bacia hidrográfica é base para o entendimento da dinâmica do ciclo hidrológico e dos impactos ocasionados por atividades humanas. Assim, a utilização de geotecnologias tem-se apresentado como uma promissora alternativa no monitoramento ambiental de bacias hidrográficas. Objetivou-se com este trabalho realizar a caracterização morfométrica da bacia hidrográfica do rio Acará, localizada no nordeste paraense, por meio de dados SRTM. Assim, determinaram-se os índices globais de forma, hierarquia fluvial, hipsometria e declividade da bacia hidrográfica. Diante dos resultados obtidos, infere-se que a Bacia Hidrográfica do Rio Acará possui forma alongada, promovendo menor concentração do deflúvio e menor exposição a grandes enchentes, com hierarquia fluvial de 6ª ordem. Em relação a sua declividade, a bacia enquadra-se, majoritariamente, nas classes plana e suave ondulado, com altitude máxima de 104,47 metros. Assim, a caracterização morfométrica de bacias hidrográficas a partir de dados SRTM mostrou vantagens como velocidade de processamento, melhor integração com dados secundários, replicabilidade e redução de intervenções manuais. Além disso, as informações geradas podem contribuir com a compreensão da dinâmica ambiental da Bacia Hidrográfica do Rio Acará, subsidiando bancos de dados para a otimização de planos de gestão.

Morphometric characterization of the Acará River Water Basin (Northeast Pará) through SRTM data A B S T R A C TCurrently, the Amazon has been suffering significant impacts through human actions as rural and urban disordered occupation, agriculture, livestock and mining. In face of this situation, the Hydric Resources National Policy, instituted by law number 9,433 from January 8 of 1997, presents the spatial administration system named water basin. Through its applicability, the water basin is base to understand the dynamic of the hydrologic cycle and of impacts caused by human activities. Thus, the geotechnology use has presented as a promising alternative in environmental monitoring of water basins. This research aims to generate the morphometric characterization of the Acará River Water Basin, localized in northeast Pará, through SRTM data. Thus, was determined the shapes global index, fluvial hierarchy, hypsometry and declivity of the water basin. According to obtained results, is possible to infer that the Acará River Water Basin has an elongated form, promoting less defluvium concentration and less exposure to large-scale flooding, with 6 th order of fluvial hierarchy. In relation to declivity, the basin fit...

“…Dd of the SRB is 2.23 km/km 2 (Toposheet), 1.9 km/km 2 (ALOS PALSAR), 1.82 km/km 2 (SRTM), 1.91 km/km 2 (Cartosat) and 1.99 km/km 2 (ASTER). Drainage density less than 2 is grouped as low, 2-4 as moderate,4-6 as high and greater than 6 is treated as very high drainage density (15) . SRB belongs to a low to moderate drainage density category, which infers the presence of permeable subsoil with good vegetation cover (16) .…”

Objectives:The goal of this research is to calculate, compare and analyze the morphometric drainage parameters of Shiriya River Basin (SRB), Kasaragod, Kerala, using DEMs acquired by different satellite sensors and topographic data (SOI toposheet) for sustainable watershed development. Methods: The Arc GIS 10.3.1 software was used to measure linear, relief, and areal aspects of morphometry. The input data used for deriving the drainage network of the SRB were SOI toposheet (1:50000 scale), SRTM DEM (90m), Cartosat, ASTER and ALOS PALSAR DEM of resolution 30 m each. The relative error percentage of basic parameters derived from DEMs concerning the toposheet is calculated. A groundwater potential map is prepared using weighted overlay analysis of thematic layers (geology, geomorphology, slope, drainage density, lineament density and depth to water level). Findings: Present study revealed that the parameters derived from SRTM DEM data are more similar to those derived from toposheet. Most of the parameters obtained from each input DEM are more or less equal, and the minor variation may be due to varied data collecting and processing methodologies used for DEM creation. SRB is characterized by 6 th order stream with a dendritic drainage pattern, which is elongated and less susceptible to soil erosion. SRB has an intermediate texture and is in a mature stage of geomorphic evolution. Inference from the ground water potential zonation map indicates that major portion of the SRB has moderate ground water potential. Application/improvement: The study would be a valuable source for identifying water recharge sites, basin modelling, and groundwater prospect mapping. Novelty:This research has attempted to compare and analyze the morphometric parameters' results from multisensor satellite data for sustainable watershed management. An attempt has been done to understand the relation between morphometric parameters and ground water potential of SRB using Groundwater potential zonation map.
