Solute Chemistry of Snowmelt and Runoff in an Alpine Basin, Sierra Nevada
Snowpack runoff contributions to the hydrochemistry of an alpine catchment in the Sierra Nevada were evaluated in 1986 and 1987 by analyzing snowpack, meltwater, and stream water samples for major inorganic ions, conductance, acid neutralizing capacity (ANC), and silicate. An ionic pulse in meltwater with initial concentrations twofold to twelvefold greater than the snowpack average, varying wi...
متن کاملPrecipitation Chemistry in and Ionic Loading to an Alpine Basin, Sierra Nevada
Wet deposition of solutes to an alpine catchment in the southern Sierra Nevada was measured from October 1984 through March 1988. Rainfall had a volume-weighted pH of 4.9, and snowfall had a volume-weighted pH of 5.3. Acetic and formic acids were important components of all wet deposition, contributing 25-30% of the measured anions in snowfall and, through analysis of charge balance deficits, t...
متن کاملSnowmelt Runoff and Water Yield along Elevation and Temperature Gradients in California’s Southern Sierra Nevada
Differences in hydrologic response across the rain-snow transition in the southern Sierra Nevada were studied in eight headwater catchments – the Kings River Experimental Watersheds – using continuous precipitation, snowpack, and streamflow measurements. The annual runoff ratio (discharge divided by precipitation) increased about 0.1 per 300 m of mean catchment elevation over the range 1,800-2,...
متن کاملInterannual variability of snowmelt in the Sierra Nevada and Rocky Mountains, United States: Examples from two alpine watersheds
[1] The distribution of snow and the energy flux components of snowmelt are intrinsic characteristics of the alpine water cycle controlling the location of source waters and the effect of climate on streamflow. Interannual variability of these characteristics is relevant to the effect of climate change on alpine hydrology. Our objective is to characterize the interannual variability in the spat...
متن کاملForeshock Probabilities in the Western Great-basin Eastern Sierra Nevada
We quantify foreshock occurrence probabilities by applying the empirical technique of Jones (1985) to the western Nevada and eastern California earthquake catalog compiled by the University of Nevada, Reno, from 1934 through 1991. The foreshock occurrence rates depend heavily on the parameters used to remove aftershocks from the catalog. It is necessary to separate the Mammoth/Mono region from ...
