Small Reservoirs Offer a New Perspective on Flood Reduction in Large Basins

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract The flood reduction potential of individual reservoirs within a large river network continuum remains poorly understood due to the complex interplay between reservoir characteristics and network properties. Here we investigate whether a collection of relatively small reservoirs can play a significant role in mediating downstream floods and ...

Dam Regulation Moderates Climate‐Induced Rice Yield Loss in the Mekong‐Tonle Sap Lake System

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Rice, a principal global staple crop, is increasingly threatened by flooding under climate change, placing rice‐dependent economies at risk. Yet the capacity of human activities to mitigate inundation impacts on rice remains insufficiently quantified.

Cascade Reservoirs Reshape Environmental Constraints on Vegetation Phenology in Alpine Riparian Ecosystems

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract With nearly two‐thirds of global long rivers regulated by dams, the development of cascade reservoirs profoundly alters riparian ecohydrology, yet isolating their net ecological effects from global warming remains a critical challenge.

Global Estimate of Reservoir Hydropower Storage Potential Based on SWOT Observations

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Hydropower is pivotal to the global transition toward carbon‐neutral energy, yet its actual potential remains constrained by uncertainties. Global assessments have traditionally relied on static metrics, such as dam height, which obscure the dynamic water fluctuations that govern operational reliability.

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

IET Smart Energy Systems, Volume 2, Issue 3, Page 223-229, September 2026.
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

Long‐Term Changes in Planktonic Ciliate Beta Diversity Under Contrasting Hydrological Regulation in A River–Floodplain System

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrological regulation by dams reshaped ciliate biodiversity over 14 years, increasing temporal compositional change and ecological uniqueness while accelerating declines in richness and density. These results highlight flood‐pulse dynamics as a fundamental mechanism sustaining biodiversity and ecological integrity in river‐floodplain ecosystems ...
