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.

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 ...

Water Resources Research, Volume 62, Issue 5, May 2026.Graphical Abstract Abstract Effective sediment management in reservoir–river coupled systems remains a global challenge due to the conflicting objectives of sediment evacuation from reservoirs and deposition reduction in downstream reaches. This study proposed a physics‐based modeling framework oriented to a reservoir–river coupled system, which ...
