ASSESSMENT AND POTENTIAL ADJUSTMENTS TO THE SNOW-RELATED ALGORITHMS IN BIOME-BGC, v4.2
Many watersheds throughout the mountain west are snow-melt dominated. Recent studies suggest that climatic shifts throughout the 20th century have diminished snowpack around the west, a trend that may accelerate in the future. Loss of critical snowpack could negatively affect the ecosystems and …

Microwave Remote Sensing of the Greenland Ice Sheet: Models and Applications
… in the data, (2) the microwave signature of the snow surface, (3) detection of snow melt, and (4) classification of snow melt. The results are applicable for identifying geophysical properties of the snow surface and monitoring changes on the ice sheet in relation to melt duration/extent, …

A landscape approach to forecasting climate change impacts on geographic ranges and phenologies of plants in the Washington Cascades
… of 2009 - 2015. We found that unusually early snow melt in low elevation meadows in 2015 caused many species to bloom out of sync across their elevation ranges, decreasing the potential for pollen dispersal between meadows. Because 2015 conditions were similar to those expected by the late 21st …

Hydrogeologic Controls on Lake Level at Mountain Lake, Virginia
… is dormant, particularly during rain-on-snow melt events. The resistivity profiles display a highly heterogeneous subsurface and reveal low-resistivity areas that suggest flow pathways to and from the lake. Well logs, satellite images, and outcrop observations appear to confirm the …

Slope Stability of the Hunter Creek Formation: A Geotechnical Investigation Near Mogul, Nevada
… to track movement over the spring of 2012 annual snow-melt. Laboratory testing included particle size distribution, specific gravity, Atterberg limits, and direct shear testing. An engineering stratigraphic column was created comparing particle size with friction angle and the plasticity of the …

Decomposition and the Freeze-Thaw Process in Northwestern Montana: A Preliminary Study
… observed on all carcasses, even after periods of snow fall and snow melt. After numerous freeze-thaw cycles, wolf 3 was still observed to linger in the advanced stage of decomposition. If applicable to humans, these results provide very useful information regarding what might occur during the …

Quantifying glacier melt enhancement due to dust deposition during the 2022 melt season. Tungnaárjökull glacier, South Iceland
Clean snow has the highest albedo of any natural surface, making snow-covered glaciers an important component of the Earth´s energy balance. However, the presence of light absorbing impurities such as mineral dust on glacier surfaces alters their reflective properties leading to a reduction in …

Machine Learning methods for providing groundwater management insights in semi-arid alluvial aquifers
… upstream reservoirs, which store rainfall and snow melt from the Snowy Mountains. Groundwater recharge inputs include floodwaters, river leakage, diffuse rainfall, and irrigation deep drainage. Substantial aquifer recharge only occurs after flooding. ML models are developed using Linear …

PASSIVE MICROWAVE SATELLITE SNOW OBSERVATIONS FOR HYDROLOGIC APPLICATIONS
Melting snow provides an essential source of water in many regions of the world and can also contribute to devastating, wide-scale flooding. The objective of this research was to investigate the potential for passive microwave remotely sensed data to characterize snow water equivalent (SWE) and …

Application of remote sensing techniques to determine the kinematics of the Bull Lake Creek landslide, Wind River Mountains, Wyoming
… and a climate that allows for large amounts of snow melt to be input into the water table. It is therefore important to gain a better understanding of how and when landslides occur, not only to minimize damage in areas with currently active landslides but also to identify landslide prone areas …

Development and Optimization of Airborne FMCW Radars for High-Resolution Snow Depth Measurements
… population relies on glaciers and seasonal snowpacks for freshwater supply. In the United States, the Colorado River Basin (CRB) gets 75% of its water from snow melt; it constitutes the water supply of 40 million people in seven states, two countries, and 5.5 million irrigated acres of land. …

Distinguishing the hydrologic regimes and vegetation of fens and wet meadows in the Rocky Mountains
… regime. Wetlands dominated by groundwater or snow melt inputs may be impacted by climate driven changes in total annual snowpack, longer summer season, and increased summer temperatures, while those influenced by seasonal precipitation will also be affected by changes in the timing, duration, …

Distribution, Relative Abundance, and Reproductive Seasonality of Larval Fish in the Red River
… discharge occurred in April and were related to snow-melt and heavy spring precipitation. In contrast, the 2000 peak in discharge occurred during the third week of June. The timing in reproduction of white sucker and Slizosledion spp. appeared to be associated primarily with temperature or …

Statistical methods for weather-related insurance claims
… weather events, for instance, heavy rainfall, snow-melt or droughts, cause large losses of lives and money every year. Insurance companies offer some form of protection against such undesirable outcomes, and decision makers want to take precautions to prevent future catastrophes. Both, decision …

Turning a problem into a solution: heterogeneities in soil hydrology
… how hydrological input signals (e.g., rainfall, snow melt) propagate through the vadose zone, turned out to be a valuable supplement to the common mass flux considerations. Neither different textures nor spatial heterogeneities affected the general kind of signal transfor-mation showing that …
