Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil

open access: yesInternational Journal of Climatology, EarlyView.
Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Multi‐objective optimization of reservoir refill operate considering energy storage and hydrological conditions

open access: yesRiver, EarlyView.
Abstract Optimizing reservoir refill operation rules is crucial for enhancing reservoir sustainability and resilience. This study proposes a refill operation model designed to derive optimal refill guide curves by considering flood risk prevention, maximum storage levels, and the combined benefits of hydropower generation and energy storage.

Role of hydraulic residence time in shaping phytoplankton community assembly in the upper yellow river cascade reservoirs

open access: yesFrontiers in Environmental Science
Introduction: Cascade hydropower development significantly alters the structure and function of river ecosystems. Phytoplankton, as primary producers, are highly sensitive to environmental changes, and their diversity and community structure reflect the ...

Practical Day‐Ahead Gas Generator Dispatch Optimisation for Enhancing the Reserved Capacity

open access: yesIET Smart Energy Systems, EarlyView.
Practical day‐ahead gas generator dispatch optimisation model is proposed to enhance the system reserved capacity. ABSTRACT In order to reduce carbon dioxide emissions, traditional coal‐fired power generation has been strictly limited in China recently, which has led to the problem of reserved capacity shortage. As one of the critical east provinces of

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).
