Planning of Cascade Hydropower Stations with the Consideration of Long‐Term Operations under Uncertainties [PDF]

Complexity, 2019
In the location‐related planning of a hydropower system, the consideration of future operations under uncertainties can make the decisions sustainable and robust. Then, it is of great importance to develop an effective approach that deals with the long‐term stochasticity due to the long‐lasting effects of the location selections.

Use of hydraulic rating to set environmental flows in the Zhangxi River, China [PDF]

, 2010
Ningbo city, China, is a rapidly growing residential and industrial centre, with a current population of 4 million. Its development has required a major water supply expansion programme providing 400,000 m3 of water per day from the upper reaches of the ...

Aquatic Productivity Signals in the Kolyma River (Northeastern Siberia) From O2/Ar Ratios and O2 Triple Isotopologues

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Arctic rivers are intricate water networks that chemically and biologically process carbon before releasing it as carbon dioxide (CO2) into the atmosphere or carrying it to the ocean. Primary producers use inorganic carbon to build biomass at the base of the trophic chain.

A Dynamic and Multidimensional Framework to Reveal and Interpret Marginal Values in Cascade Reservoir Scheduling Under Competing Demands

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Global climate change and growing water demand exacerbate the imbalances in reservoir resource allocation, necessitating advanced frameworks that move beyond static valuation methods. Traditional valuation methods, constrained by static or homogenized assumptions, fail to capture the spatiotemporal heterogeneity and dynamic trade‐offs inherent

Like a fish takes to water: Minimum discharge requirements to sustain rheophilic fish community dominance in bypassed river reaches

Journal of Applied Ecology, Volume 62, Issue 12, Page 3263-3276, December 2025.
We conclude that small increases in minimum discharge can be particularly beneficial to the restoration of rheophilic community structure, especially at low levels of minimum flow, even though the area of lotic habitat has been reduced to a fraction of natural conditions.

Optimal Dispatch of Pumped Storage Hydro Cascade under Uncertainty [PDF]

, 2018
In this paper, we propose an optimal dispatch scheme for a pumped storage hydro cascade that maximizes the energy per cubic meter of water in the system taking into account uncertainty in the net load variations.

Emerging Patterns of Changes in Intra‐Annual Variability of Streamflow

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Large‐sample observational analyses of changes in intra‐annual streamflow variability remain rare. This study presents the first large‐scale analysis of spatial patterns in long‐term trends of intra‐annual streamflow variability from 1970 to 2022 across free‐flowing and non‐free‐flowing rivers in diverse climate zones.
