Flow Measurement Methods in Small Tributaries of the Teles Pires River, Southern of the Amazon Hydrological Region

“…The management of water resources is increasingly necessary given its importance for the various hydrological realities and the increase in the multiple demands for the use of water for human needs, industrial needs, animal watering, agricultural irrigation, energy generation, recreation, tourism, navigation, maintenance of natural ecosystems, among others [1]. In recent decades, with population growth, conflicts associated with water use have significantly increased in socioeconomic aspects, regardless of the spatial scale [2].…”

“…The in situ determination of flow in natural watercourses is fundamental for the definition of key curves and the calibration of hydrological models that allow for the forecasting of flood events, water scarcity, soil loss, and silting of reservoirs, in addition to helping in the taking mitigating measures for these problems, such as implementing appropriate land management practices [9,29], defining hydro-agricultural and forestry projects associated with climate change [30], regulating outflows in reservoirs [31], and supplying water for various human activities [1]. It is also worth mentioning morphodynamic river modeling, which is of paramount relevance to predicting river evolution and preventing hydraulic risk.…”

“…The management of water resources is increasingly necessary, given its importance for the various hydrological realities and the increase in the multiple demands for the use of water for human, industrial, animal watering, agricultural irrigation, energy generation, recreation, tourism, navigation, maintenance of natural ecosystems, among others [1]. In recent decades, with population growth, conflicts associated with water use have increased significantly in socioeconomic aspects, 2 regardless of the spatial scale [1]. In this sense, for adequate water management, it is necessary to understand and quantify this natural resource through the components of the hydrological cycle in hydrographic basins.…”

“…The in loco determination of flow in natural watercourses is fundamental for the definition of key curves and calibration of hydrological models that allow forecasting of flood events, water scarcity, soil loss and silting of reservoirs, in addition to helping in the taking mitigating measures for these problems, such as implementing appropriate land management practices [7,15], defining hydro-agricultural and forestry projects [16], regulating outflows in reservoirs [17] and supplying water for various human activities [1].…”

Aplicação de indicador de estresse hídrico na Bacia do Rio Tibagi para a identificação de bacias críticas quanto ao uso dos recursos hídricos

“…Assim, promovendo os princípios de gestão descentralizada e participativa, previstos na Lei 9.433/1997, a Resolução CERH 09/2020 também define a alocação negociada, que vem a ser o processo em que os usuários de uma determinada região hidrográfica (crítica) se reúnem para decidir de forma conjunta, com base em estudos e previsões de disponibilidade hídrica, a quantidade de água a ser utilizada por cada um deles ao longo de um determinado período. Tal conceito é equivalente às demais definições existentes ao redor do país (Stinghen & Mannich, 2022).…”
