Dispersal of fish eggs and larvae in a cascade of small hydropower plants with fish ladders

Hydrobiologia, 2020
This study was conducted to investigate fish eggs and larvae dispersal in a river stretch influenced by small hydropower plants in Southeast Brazil. The main hypothesis is that the downstream dispersal of free-flowing eggs and larvae is likely to occur given the small size of the studied reservoirs and that passage through the dam may occur, with the ...

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

International Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

Conservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

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.

Optimal Re-Dispatching of Cascaded Hydropower Plants Using Quadratic Programming and Chance-Constrained Programming [PDF]

Energies, 2019
Stochastic production from wind power plants imposes additional uncertainty in power system operation. It can cause problems in load and generation balancing in the power system and can also cause congestion in the transmission network. This paper deals with the problems of congestion in the transmission network, which are caused by the production of ...

A review of empirical dam breach models

River, Volume 5, Issue 3, Page 328-350, August 2026.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...
