Connected reservoirs: Modeling aquatic ecosystems along a cascade system in Brazil

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Connected reservoirs along cascade systems have been constructed along large rivers worldwide, establishing a network of aquatic environments that greatly affect matter flux and ecological dynamics. Here, we explore the underlying ecological principles of their unidirectional connectivity, applying a modeling framework that explicitly links ...

Production Planning of Cascaded Hydropower Stations using Approximate Dynamic Programming

IFAC-PapersOnLine, 2023
We formulate the day-ahead bidding problem for a hydropower producer having several hydropower plants residing in a river basin. We present a novel approach inspired by Dynamic programming with approximations in value and policy space by neural networks.

Stability Analysis of a Run-of-River Diversion Hydropower Plant With Surge Tank And Spillway in the Head Pond [PDF]

, 2014
Run-of-river hydropower plants usually lack significant storage capacity; therefore, the more adequate control strategy would consist of keeping a constant water level at the intake pond in order to harness the maximum amount of energy from the river ...

Enhancing Infrastructure Resilience in Service Utilities through Embedding Versatility in System Architecture

Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1295-1313, May/June 2026.
ABSTRACT Enhancing infrastructure resilience, a key component of transforming and sustainably developing service utilities, requires a transdisciplinary and systems engineering framework. Addressing vulnerabilities in system architecture offers opportunities for resilience improvements, thereby mitigating the environmental, social, and economic impacts

Impacts of cascade run-of-river dams on benthic diatoms in the Xiangxi River, China [PDF]

, 2010
The ecological effects of small run-of-river dams on aquatic ecosystems are poorly understood, especially on downstream benthic algal communities. We examined impacts of such dams on the benthic diatom community at a regional scale in the Xiangxi River ...

A Method to Implement Natural Flow Regimes for Regulated Rivers

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Rivers throughout the world have been dammed for flood control, irrigation, hydropower, and water storage for centuries. Dams service the economic and development needs of societies, but degrade the ecology of rivers. To conserve diminishing aquatic species and their habitats, methods are needed to help managers implement flow releases with ...
