The aim of this paper is to provide some informations on wet snow avalanche dynamics and debris transport through the analysis of 25 snow avalanche deposits on alpine screes in the Ecrins Massif, and in the Devoluy and the Vanoise massifs.

This paper discusses the results of a lichenometrical and geomorphological study of one of the few remaining active snow hollows in the central region of the Iberian Peninsula. The study area, located on a glacial shoulder, is called Hoya del
of the snow cover. These data formed the basis for a study of the lichen colonization on the blocks and on the wall surrounding the snow hollow.

-month spatial climatology of snow cover (duration and depth) was constructed for the region along with a 60-year temporal analysis of areally averaged snow cover. A spatial climatology of diurnal snowmelt, stratified by the magnitude of melt, also
Morphometric variables associated with 36 debris torrent, 78 snow avalanche, 45 composite debris torrent and snow avalanche and 14 streamflow basins in the Cascade Mountains of southwestern British Columbia, Canada are examined. The results show
significant statistical differences in top and bottom elevations, relief, channel length and gradient, basin area, fan gradient and area, and basin ruggedness between snow avalanche basins and the 2 basin types affected by debris torrents, reflecting the very
The history of the landscape of the Haramosh valley is linked with the former glaciation history of the Indus Valley. The extent of the former glaciers Mani, Baska and Phuparash according to their glacio-geomorphic position, their snow line

This review shows that glacial features identifiable from aerial photographs and satellite imagery include spatial extent, transient snowline, equilibrium line elevation, accumulation and ablation zones, and differentiation of ice/snow. Digital
