Leaky dams have become essential nature-based solutions for flood management, providing sustainable alternatives to traditional engineered control methods. This review delves into the mechanisms by which leaky operate, including regulation of water flow through velocity reduction and distribution across floodplains, effective sediment trapping soil quality enhancement, facilitation groundwater recharge table stabilization. These structures not only mitigate peak flows reduce erosion but also contribute enhanced biodiversity creating diverse aquatic habitats maintaining ecological connectivity. The effectiveness is assessed various performance metrics, demonstrating significant reductions in flows, improved increased levels, collectively enhance ecosystem resilience quality. However, implementation presents several technical challenges, such as design complexity, hydrological variability, maintenance requirements, socio-economic factors like land use conflicts economic viability. Additionally, while offer numerous environmental benefits, potential negative impacts include habitat disruption, accumulation, alterations quality, necessitate careful planning adaptive management strategies. Emerging trends dam development focus on integration smart technologies, real-time monitoring systems artificial intelligence, optimize against climate-induced extreme weather events. Advances modeling technologies are facilitating networks, promoting their incorporation comprehensive watershed frameworks. highlights integral components systems, advocating broader adoption alongside conventional engineering achieve resilient ecologically balanced management.

O acompanhamento de áreas aquáticas, com a presença atividades essenciais relevantes, como geração energia elétrica, é extremamente importante para um bom funcionamento dos processos mecânicos da usina. Nesse caso, as situações decorrentes eutrofização do corpo hídrico, tais florescimentos algas e macrófitas, por exemplo, podem ser prejudiciais ao hidrelétricas. Este artigo tem objetivo apresentar o Sensoriamento Remoto fins monitoramento recursos hídricos reservatório Itaipu, discutir metodologia mapeamento os produtos resultantes deste monitoramento. A solução foi uso imagens sensores alta média resolução; constelação Planet, que possui cerca 175 satélites operacionais, 04 bandas multiespectrais (azul, verde, vermelho infravermelho próximo), resolução radiométrica 12 bits, ortorretificadas 3 metros espacial, possuem capacidade recobrimento diário, além disponibilizadas gratuitamente Sentinel 2, revisita 5 dias espacial 10 metros, utilizadas identificações suas resoluções espaciais temporais atendessem levantamento.
