The upper Benue River watershed is undergoing remarkable modifications due to man-made and natural phenomena. Hence, an evaluation is required to understand the hydrological process of the watershed for planning and management strategies. This study aimed to assess the morphometric characteristics and prioritize the upper Benue River watershed. The boundary of the watershed and sub-watersheds, as well as stream networks, was extracted from the digital elevation model (DEM) coupled with hydrological and topographic maps. Twenty-eight morphometric parameters under three categories, i.e. linear, areal, and relief aspects were computed and mapped. Findings from the study revealed that the watershed is a seventh stream order system characterized by a dendritic drainage pattern. The result also showed that 4821 streams were extracted with a cumulative length of 30,232.84 km. The hypsometric integral of the watershed was estimated to be 0.22, indicating that it is in the old stage. In the prioritization of the watershed, the morphometric variables were utilized to calculate and classify the compound factor. The result showed that sub-watersheds 12, 16, 18, 24, 26, and 27 were ranked as very high priority for which conservation measures are required to mitigate the risk of flood and erosion. The outcome of this study can be used by decision-makers for sustainable watershed management and planning.

“…So, the infiltration characteristics vary within the basin. The greater energy at steep uplands and lowlands causes quicker drainage with less scope for infiltration into the ground at these locations, whereas the flat terrain shown by hypsometric curve in between showing moderate to less slope possesses different infiltration characteristics in accordance with (Oyatayo et al 2017). Another consequence of the higher energy is the scope for erosion in the basin, particularly at locations closer to steeper relief.…”

“…The higher relief found in Arkavathy river basin indicates greater energy available in the drainage system of the basin. Despite higher relief, the infiltration characteristics in the basin depend on numerous variables such as slope of the terrain (such as steep slope of uplands and lowlands in the basin and flat terrain in between), rainfall, vegetation, subsurface material and the nature of human interference in the basin across various stream orders which is also reflected by the drainage density (Oyatayo et al 2017;Sukristiyanti et al 2018). So, the infiltration characteristics vary within the basin.…”

Water availability and water scarcity in a river basin are influenced by the geomorphological processes occurring within a river basin. Therefore, quantitative evaluation of the river basin shape provides a crucial lead in assessment of the impact of geomorphological processes on the hydrology of the basin. Arkavathy river basin has been selected for the present study. The basin with an annual average rainfall of 874.87 mm is a persistent water scarce basin located in Cauvery river basin in south India. The basin has been subjected to rapid urbanization due to which there is an increased water demand over a period of time. Hence, to tackle the growing water scarcity and reoccurrence of droughts in the basin, an attempt has been made in the present study to investigate and understand the basin morphometry and derivation of hypsometric curve of Arkavathy river basin using remote sensing (RS) and geographic information system (GIS) techniques. Quantitative evaluation of basin morphometry has been made, and the impact of basin morphometry on the peak runoff and flooding in the basin has been assessed. The basin hypsometric curve has aided in assessment of the erosion status of the basin and its impact on the risk of sedimentation on water bodies. The morphometric parameters and hypsometric curve are then analysed to investigate the potential impact of the basin morphometry on the water availability and water scarcity afflicting the basin.

“…Os atributos fisiográficos de bacias hidrográficas afetam diretamente os processos hidrológicos, climáticos e as atividades humanas, como o agronegócio, o abastecimento público, a indústria e a produção de energia hidrelétrica. Portanto, o seu conhecimento é essencial para diagnosticar as alterações, com e sem interferências antrópicas, e traçar planos de controle, adaptação e monitoramento para os novos cenários desencadeados pelas mudanças climáticas locais e globais (TAOFIK et al 2017).…”

“…As técnicas de geoprocessamento e de sensoriamento remoto são eficazes para determinação dos parâmetros morfométricos e permitem calcular atributos como a densidade de drenagem, o índice de bifurcação e a relação de relevo de bacias hidrográficas de forma automatizada e com custos reduzidos, colaborando para apontar áreas prioritárias e urgentes para investimentos na conservação dos recursos naturais e para elaboração de planos de manejo para as áreas com riscos à enchentes e inundações (TAOFIK et al 2017). Quando combinados, os elementos de geoprocessamento e de sistema de informação geográfica (SIG) possibilitam avaliar e monitorar, tanto quantitativa, como qualitativamente, fenômenos e eventos ambientais e, assim, contribuir com informações para sustentar e amparar as tomadas de decisões por órgãos públicos e privados (TAOFIK et al 2017).…”

A caracterização morfométrica de bacias hidrográficas é fundamental para análises hidrológicas e ambientais. Pois, pode contribuir com políticas de planejamento e gerenciamento de recursos naturais e de prevenção à enchentes e inundações. Neste cenário, o trabalho analisou as características morfométricas e hidrológicas da Bacia Hidrográfica do Alto Sapucaí, sul do Estado de Minas Gerais, para fornecer subsídios técnicos para o adequado gerenciamento dos seus recursos hídricos. Para tanto, foram calculados os parâmetros: densidade de rios, densidade de drenagem, relação de relevo, índice de rugosidade, coeficiente de compacidade, fator de forma e coeficiente de manutenção. Os dados referentes à vazão foram obtidos de uma estação de monitoramento fluvial da Agência Nacional de Águas e organizados pelo Sistema Computacional para Análise Hidrológica e pelo aplicativo Excel para obtenção, no período de 1994 a 2013, da vazão média anual, vazão média de longo prazo, vazão máxima de longo prazo, vazão mínima de longo prazo e os desvios em relação à média. Os dados de precipitação foram obtidos pelo Climate Hazards Group Infrared Precipitation with Stations e reunidos em precipitação média mensal e precipitação média anual para o período. Os dados permitiram caracterizar a Bacia Hidrográfica do Alto Sapucaí como propensa a enchentes, devido aos valores de densidade de drenagem maiores que 15,01, de densidade de rios maiores do que 3,01 e coeficiente de compacidade de 0,89. Tais valores indicam a necessidade de estratégias de prevenção à enchentes e inundações, como o reestabelecimento de áreas verdes e evitar a ocupação antrópica nessas áreas.
