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...

The study presents investigations of the runoff from snow and ice, carried out in the high alpine basin of the Rhône river at Sion (3371 km2, 491 -4634 m a.s.l.). Using satellite remote sensing data, features like the snow coverage in the whole basin, the gradually decreasing snow coverage on glaciers and the area of exposed ice have been mapped. The periodical monitoring of the basin is based ...

Kendall’s test was used to analyze the hydro-climatic trends of the Yellow River over the last half century. The results show that: (1) the runoff of the basin has decreased even after allowing for human uses, (2) the watershed has become warmer with a more significant increase in minimum temperature than in mean and maximum temperatures, and (3) no significant change in precipitation trend was...
