Meltwater stream temperature responses to air temperature and characteristics
… of size of glacier catchment area, air temperature, stream characteristics including distance travelled by meltwater in determining water temperature in meltwater rivers draining from Alpine Glaciers. Hood et al, (2013) suggested that percentage glacierisation was the determining …

Gulf Stream temperature, salinity and transport during the last millennium
… of Florida reveal significant changes in Gulf Stream cross-current density gradient during the last millennium. These data imply that Gulf Stream transport during the Little Ice Age (LIA: 1200-1850 A.D.) was 2-3 Sv lower than today. The timing of reduced flow is consistent with cold conditions …

Development and evaluation of a stream temperature component within the PRMS watershed modeling program
Stream temperature is becoming a very important factor in water quality and the health of many aquatic ecosystems. Computer modeling software can help predict the response of watershed and stream systems to changes in climate or other conditions. This thesis project concerns the development of a …

Stream temperature dynamics following riparian wildfire : effects of stream-subsurface interactions and standing dead trees
… objectives of this study were to address how stream temperature is influenced by (1) spatial variability in energy exchanges, (2) reach-scale stream-subsurface water interactions and (3) the net radiation dynamics associated with standing dead riparian vegetation. Stream temperature, riparian …

Evaluation and Use of Stream Temperature Prediction Models for Instream Flow and Fish Habitat Management
… Agency), and RQUAL (Tennessee Valley Authority) stream temperature prediction models were evaluated. All models had high predictive ability with the majority of predictions, >80% for Back Creek (Roanoke County, VA) and >90% for the Smith River tailwater (SRT) (Patrick County, VA), within 3°C of …

Statistical Modeling and Analysis of Bivariate Spatial-Temporal Data with the Application to Stream Temperature Study
Water temperature is a critical factor for the quality and biological condition of streams. Among various factors affecting stream water temperature, air temperature is one of the most important factors related to water temperature. To appropriately quantify the relationship between water and air …

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 …

Implications for Restoration: Effects of Riparian Vegetation and Shade on Temperature Gradients in Lower Gold Creek, Southwest Montana
Stream temperature impairment is a significant problem in the western United States and throughout Montana. Stream temperature is a measure of the amount of heat energy per unit volume of water. Change in either the amount of heat energy entering the stream or the amount of water flowing in the …

Hydrologic Characteristics of Summer Stream Temperatures in Little Creek and Scotts Creek at the Swanton Pacific Ranch
<p>Stream temperature impacts have resulted in increased restrictions on land management such as timber harvest and have created considerable uncertainty for future planning and management of redwood forestlands. Challenges remain in the assessment of downstream cumulative effects given the …

Modeling the temperature response of small rivers to land cover changes using satellite-based spatial data
… 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 length: …

An Investigation of Spatial and Temporal Variability in Several of Montana's Reference Streams: Working Toward a More Holistic Management Strategy
Water temperature is a physical property that fundamentally affects stream ecology and is considered an important water quality parameter from scientific and legal view points. On global, catchment and reach scales, anthropogenic activities have substantially altered natural stream temperature …

Influences of land use on the structure and function of headwater streams: A multiple scale analysis
The structure and function of stream ecosystems may be strongly influenced by land-use practices within watersheds. The magnitude of land-use impacts may depend upon the spatial arrangement of development in watersheds. This study examines the relationship between land-cover patterns and stream …
