River temperature behaviour in changing environments: trends, patterns at different spatial and temporal scales and role as a stressor
River/stream water temperature is one of the master water quality parameters as it controls several key iogeochemical, physical and ecological processes and river ecosystem functioning. Thermal regimes of several rivers have been substantially altered by climate change and other anthropogenic …

Better understanding human impacts on river thermal regimes under climate change
… dam construction, greatly modify the response of river thermal regimes to climate change. Dams impound large water bodies, decrease surface to volume ratios, and increase water residence times. All of these changes affect the interaction between surface meteorology and river systems. During warm …

Modeling the temperature response of small rivers to land cover changes using satellite-based spatial data
… cover alteration on water quality, including river temperatures, has important ecological implications. However, there is a dearth of information on temperature of rivers smaller than about 60 m wide (approximately fifth order and below), which constitute roughly 97% of total global stream …

Factors influencing infectious agent communities and infection burden in free-ranging migratory adult salmonids across Canada
… To investigate the influence of high water temperatures, Atlantic salmon were experimentally displaced downstream of a barrier and periodically sampled to track changes in infectious agent prevalence, relative infection burden, and host response over a 32 day period. Here, river temperature …

Modeling the stream temperature regime of the East Fork of the Virgin River in Zion National Park
The following stream temperature study was conducted as part of a general study by the Water Rights Branch, Water Resources Division, National Park Service, to evaluate the physical habitat of the aquatic organisms within Zion National Park (ZION). Stream temperature is an aquatic habitat …

Impacts of Carbonate Mineral Weathering on Hydrochemistry of the Upper Green River Basin, Kentucky
<p>Kentucky’s Upper Green River Basin has received significant attention due to the area’s high biodiversity and spectacular karst development. While carbonate bedrock is present throughout the watershed, it is more extensive and homogenous along the river between Greensburg and Munfordville than …

Effects of abiotic and biotic factors on population dynamics of brook trout (<i>Salvelinus fontinalis</i>) within Shenandoah National Park, Virginia
… environmental correlates (e.g., streamflow, temperature) and brook trout abundance and recruitment in Shenandoah National Park, VA for the first time. In Chapter 1, I use generalized linear mixed-models and long-term fish collections data from the National Park Service (1996-2021) to …
