DISTRIBUTED ENERGETICS OF BOREAL FOREST SNOWMELT
The energetics of snowmelt under boreal forest canopies in central Saskatchewan were examined with respect to the influence of forest canopy structure on the snow cover depletionrate. The distribution of snow water equivalent was examined prior to melt and during melt in five distinct boreal forest …

Simulating Areal Snowcover Depletion and Snowmelt Runoff in Alpine Terrain
… in the headwaters of the Rocky Mountains, where snowmelt represents the greatest single contribution. Increasing concerns over future regional water resource stresses require better understanding and prediction of some alpine snow hydrology components, which are currently limited due to the large …

Development and Application of a MODIS Snowmelt Model for Northwestern Montana
… Development and Application of a MODIS Driven Snowmelt Model in Northwestern Montana Chairperson: Joel T. Harper In the mountain west the timing of the spring snowmelt pulse has considerable impact on water resources and ecological processes such as fire. A forward shift of this timing due to …

Snowmelt Detection on Alpine Glaciers using Synthetic Aperture Radar Time Series
… of sensitive aquatic alpine ecosystems. As snowmelt onsets sooner, lasts longer, and snowfields retreat due to increases in global temperature, the hydrologic dynamics of catchments draining HKH threaten to change the availability of surface freshwater resources for nearly one fifth of the …

Snow Hydrology and Streamflow Response to Snowmelt: A Case Study on SWE Dataset Comparisons, Regional Water Balance, and Snowmelt-Induced Runoff within the Smith River Watershed, Montana
… assess the regional water balance, and quantify snowmelt contributions to runoff. SWE estimates from five open-source datasets (UA 4km, UA 800m, WUS-SR, SNODAS, and Noah-MP via WLDAS) and SnowModel were validated against observations from five Snow Telemetry (SNOTEL) stations using correlation …

The Effects of Snowmelt Percolation on Stratified Pollen Records: A Cooler Study
<p>Temperate valley glaciers may contain unique paleoecological records with the possibility of very high-resolution pollen analysis. However, little is known about the effects of meltwater percolation on pollen found in snow and glacial ice. Previous studies have suggested that pollen is …

Multi-scale hydrogeomorphic influences on bull trout spawning habitat in snowmelt-dominated headwater streams
… spatial scales in gravel-bed, pool-riffle, snowmelt dominated headwater streams of northwestern Montana. Subreach redd occurrence tended to be associated with the finest available textural facies. In subreach streambed sections hosting bull trout redds, redd density was significantly (at …

The Impact of Climate Change upon the Snowmelt Hydrology of an Upland UK Catchment
Snowmelt hydrology is important in the winter flow regime of upland catchments in the UK as it can attenuate the extremes of the river flow hydrograph. The sensitivity of snow accumulation and melt to changes in climate, in particular to increases in temperature, could impact upon the variability …

The effects of input data degradation on hydrological model performance for a snowmelt dominated watershed
… in this study to model a portion of the snowmelt dominated Yampa River watershed in northwest Colorado. An analysis scheme is followed to capture the model's dependence on representative meteorological stations located in an around the modeled basin. Many regions in the United States …

Energy controls on diurnal snowmelt events and stream recharge, Lost Horse Canyon, Bitterroot Mountains, MT
Streamflow and groundwater response to snowmelt in forested subalpine catchments carry integrated information about snowmelt events within the basin at different temporal scales. High frequency snowmelt events are often dominated by the day-night cycle, which is reflected in groundwater and …

Using MODIS Satellite Images to Confirm Distributed Snowmelt Model Results in a Small Arctic Watershed
… for using MODIS to confirm model predictions of snowmelt that occur across less than 150 km2 and less than a few days, however, clouds and malfunctioning sensors limit such use.

Delay of Spring Snowmelt due to Storm-Induced Changes in Snowpack, Columbia River Headwaters, Western Montana, USA
The timing of mountain snowmelt is important for water resources in western Montana, where the majority of annual precipitation falls as snow. During the snowmelt season, the melting snowpack is subjected to a continuum of snow accumulation and/or sustained subfreezing temperature episodes that …

Snowmelt and rainfall runoff in burned and unburned catchments at the intermittent-persistent snow transition, Colorado Front Range
Winter snowmelt and summer monsoonal rains are the dominant sources for streamflow in the Colorado Front Range, and wildfire can greatly affect the hydrologic regime through which these inputs are delivered to the stream. However, the specific changes to the hydrologic processes that drive runoff …
