Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

River Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and

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

Frontiers 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 ...

Analysis of Reservoir Regulation Capacity Based on Cascade POA Optimal Scheduling Model

Renmin Zhujiang, 2021
Due to the completion of the cascade reservoirs,the hydrological process of the basin has changed significantly,and the scheduling of the existing reservoirs has changed.The assessment of the regulation capacity of the existing reservoirs will help to re-

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Effects of Reduced Precipitation and Water Level Variability on Phytoplankton Dynamics and Thermal Structure in a Large Tropical Reservoir

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Drought is one of the most severe and complex natural hazards causing changes in water balance and impeding crucial water‐dependent ecosystem services. Over the last 25 years, multiple severe droughts linked to El Niño events have affected the Zambian and Zimbabwean regions.

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

Fisheries Management and Ecology, Volume 33, Issue 5, Page 963-976, October 2026.
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).

Simulation of hydraulic power matching–based risk and economic evaluation among cascade hydropower stations in spot transactions

Frontiers in Energy Research, 2022
The electricity market is evolving rapidly from pre-bid to spot markets, where the transactions between producers and consumers have become crucial and are vulnerable to safety risks.

Spatio‐Temporal Assessment of Fish Biodiversity in High‐Density Cascade Dam Rivers Using Environmental DNA Metabarcoding

Biological Diversity, Volume 3, Issue 3, Page 158-168, September 2026.
This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with

The optimal equilibrium operation between power generation and ecology of Qingjiang cascade hydropower stations

MATEC Web of Conferences, 2018
Ecological operation of cascade hydropower stations is one of the most important methods for the ecological restoration of a river system. In order to balance the benefits between power generation and ecology of Qingjiang cascade hydropower station, an ...

Hydroclimatic Changes in the Marsyangdi River Basin, Central Himalaya Under CMIP6 Scenarios: Implications for the Water–Energy–Food–Ecosystem Nexus

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
Under CMIP6 scenarios in the Marsyangdi River Basin, SWAT+ simulations show that warming and shifting precipitation diminish snowfall and cryospheric buffering, deepening pre‐monsoon flow deficits. This seasonal mismatch drives critical Water–Energy–Food–Ecosystem trade‐offs: dry‐season run‐of‐river hydropower generation drop, and increase in winter ...
