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

International Journal of Climatology, Volume 46, Issue 9, July 2026.
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

Preliminary Exploration of Establishing a Spot Quotation Alliance for Cascade Hydropower Stations

IOP Conference Series: Earth and Environmental Science, 2021
Abstract For the spot electricity market, the quotation combining the hydropower stations is more resistant to uncertainties of runoff and spot price in market bidding. Therefore, it is of great significance to set up a spot quotation system for these hydropower stations.

Reconstructing China's Natural Streamflow at 1‐km Resolution

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Climate change and intensifying human activities are placing unprecedented pressure on China's water resources, necessitating high‐resolution, naturalized streamflow records for effective management. We develop a 1‐km gridded fully coupled land‐surface‐hydrologic‐hydrodynamic modeling system for China based on the CLHMSv2.0 model.

Native and Non‐Native Populations Respond Unevenly to River Barrier Removals

Global Change Biology, Volume 32, Issue 6, June 2026.
While barrier removals restore river connectivity and promote recovery of native populations, they may also facilitate non‐native species, creating a ‘connectivity conundrum’. Using a systematic review and meta‐analysis, we show that both native and non‐native populations can benefit from barrier removal, with outcomes being context‐dependent ...
