Investigating the Effects of Flue Gas Injection, Hot Water Distribution, and Fill Distribution on Natural Draft Wet Cooling Tower Performance [PDF]
, 2020 Natural draft wet cooling towers (NDWCT) are a common method of heat removal in powerplants. This study employs a numerical cooling tower model developed by Eldredge, Benton & Hodgson (1997) to examine whether utilizing nonuniform water, fill profiles ...

Limnology and Oceanography, Volume 71, Issue 4, April 2026.Abstract Coastal systems provide habitat that sustains valuable shellfisheries but are subject to dissolved oxygen (DO) and/or carbonate chemistry impairment from anthropogenic pressures such as eutrophication and increasingly, climate change. Although extreme events can have disproportional negative ecological impacts, their ephemeral nature and a ...

Channel Evolution During Drawdown of Iron Gate and Copco I Reservoirs, Klamath River, CA
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract This study used the world's largest dam removal on the Klamath River to investigate channel evolution in unconsolidated silt and clay sediment during reservoir drawdown. Timelapse imagery revealed retrogressing rotational slides and flowslides as key sources of sediment to the re‐emerging channels.
