... fork/TDR methods. In practice, TDR (or fork) probes usually investigate only a small volume of snow; thus, to retrieve a velocity value that could be representative of the velocity in the overall snowpack thickness, measurements at different depths must be collected and properly averaged. One potential...

.... Perennial snowpack in the alcove for Gully A. The image was acquired on 29 November 2010. The debris-rich snowpack is heavily dissected by stream channels that were active during the austral spring of November 2010. Fig. 21. Difference between the temperature on the valley wall and on the valley...

... (0.4 m thick in all model runs); in the second, air temperatures act upon an overlying snowpack that insulates the ice (0.3 m thick). In both cases, the bottom of the ice layer is held at a constant 0 °C to mimic contact with lake water, and the temperature at the top of the ice or snow is assumed...

...Lino Schmid; Jürg Schweizer; John Bradford; Hansruedi Maurer ABSTRACT Snow stratigraphy and liquid water content are key contributing factors to avalanche formation. Upward-looking ground-penetrating radar (upGPR) systems allow nondestructive monitoring of the snowpack, but deriving density...

... recharge and streamflow has long been known. This study was conducted to investigate the variability of soil wetting and drying dynamics within a network of soil moisture sensors beneath a seasonally persistent snowpack in California’s southern Sierra Nevada. Data were analyzed to quantify the persistence...

... plays a key role in the isotope hydrology of meteoric water systems in the continental interior southwestern United States. We demonstrate that altitude-dependent sublimation of the winter snowpack is a viable mechanism for the observed isotopic enrichment and reduced δ 18 O-elevation gradients of Basin...

... subcatchment of the Dry Creek Experimental Watershed near Boise, ID ( Fig. 1 ). The subcatchment elevation ranges from 1600 to 1645 m above sea level. The summers are hot and dry. Winters are cold, with a persistent snowpack from around early November through March or April. Approximately half of the average...

...) may metamorphose into smaller, rounder, and sintered grains that bond together creating a strong snow layer, or the grains may transform into larger, faceted, and looser grains creating a weak snow layer. During the season the snowpack builds from a series of storms, each depositing another layer...
