Thermal pollution modeling of the New River
Thermal plume data from the Glen Lyn, Virginia power plant on the New River was compared to the thermal plume data from a hydraulic river model of this section of river. Both summer (high temperature, low river flow) and winter (low temperature, high river flow) conditions were modeled. The model …

Thermal Pollution in Urban Streams of the North Carolina Piedmont
… (Allen 1995, Kingsolver and Huey 2008). Thermal changes control and can alter basic morphological features of biota, such as size and growth rates (Gibbons 1970, Kingsolver and Huey 2008). USS synthesis reports have called for further research into the processes by which urban areas …

Thermal Pollution Mitigation in Cold Water Stream Watersheds Using Bioretention
… use of bioretention as a strategy to reduce the thermal impact associated with urban stormwater runoff in developing cold water stream watersheds. Temperature and flow data were collected during ten controlled trials at a bioretention facility located in Blacksburg, Virginia. It was determined …

Development of Effective Procedures for Stormwater Thermal Pollution Potential Risk Mapping
Thermal pollution of waterbodies occurring from heated stormwater runoff in urban catchments is a growing concern among municipalities in the United States. The U.S. Environmental Protection Agency (EPA) maintains regulatory criteria for temperature of waters of the U.S. as many species of aquatic …

Modeling Watershed-Wide Bioretention Stormwater Retrofits to Achieve Thermal Pollution Mitigation Goals
Stream ecosystems are increasingly at risk for thermal impairment as urbanization intensifies, resulting in more heated runoff from impervious cover that is less likely to be cooled naturally. While several best management practices, including bioretention filters, have been able to reduce thermal …

Integrating thermoelectric power generation operations with aquatic ecosystem sustainability
… for cooling purposes. This process can cause thermal pollution in waterways, adversely affecting aquatic ecosystems. Incorporating biology into the energy-water nexus can aid decision-makers in identifying tradeoffs and more effectively assessing and managing aquatic ecosystems. The central …

Analysing stormwater temperature at site-specific discharge points along the Liesbeek River, South Africa
… a strong link between expanding urbanisation and thermal impacts on streams and rivers draining urban catchments (Roa-Espinosa et al., 2003; Arrington, 2003; Herb et al., 2009b). Anthropogenic perturbations such as thermal pollution can adversely disturb the natural thermal regime of a river …

Managing impacts of hydrological droughts and heat waves on thermal power plants
… discharge, and consumption of water, used in thermal power plant cooling processes, is a leading driver of thermal pollution in waterways, and can contribute to water allocation challenges. Conversely, the reliance of thermal generation on large amounts of cooling water at suitable …

Physio-morphological effects of abrupt thermal stress on diatoms
… and communities of aquatic organisms to thermal pollution can thus be anticipated when natural water systems are utilized as a cooling source. The majority of research effort relative to the effects of heated waste waters on aquatic systems has been directed towards macro- as opposed to …

Essays on trade, CO₂, and the environment
… undertake to protect themselves against air pollution. We analyze how the NOx Budget Trading Program, a large cap-and-trade market in the Eastern U.S., affected air pollution emissions, ambient air quality, medication purchases, hospitalizations, and mortality. We find that the market …

An Investigation of Spatial and Temporal Variability in Several of Montana's Reference Streams: Working Toward a More Holistic Management Strategy
… ability to maintain ecological integrity. Thermal degradation often can be attributed to a variety of human activities, and global climate change, which has been accelerated by the demands of an exponentially expanding human population, will play a central role in defining stream …

The influence of embryo incubation temperature on later life aerobic performance of Lake Whitefish (Coregonus clupeaformis) and Yellow Perch (Perca flavescens)
… levels. In modern times, climate change and thermal pollution pose major threats as they threaten to elevate water temperatures, therefore limiting optimal thermal habitats and exposing species to suboptimal environmental conditions. While adult fish of many species have the capacity to avoid …

Investigating population structure and resource use diversity in Lake Huron Lake (Coregonus clupeaformis) and Round (Prosopium cylindraceum) Whitefish using compound specific stable isotopes analysis
Aquatic thermal pollution from electricity generation, via once-through cooling systems, poses a potential threat to freshwater ecosystems. Research has shown that elevated temperatures can have adverse effects on whitefish reproduction and development, potentially leading to population decline. …

Changes in Stormwater Thermal Loads Due to Bioretention Cells
… surfaces temperatures, and then transfer this thermal energy to runoff during a rainfall event, resulting in higher runoff temperatures. Bioretention cells are a common stormwater control practice identified as a possible thermal mitigation practice in urban watersheds harboring cold-water fish …
