Karst du Rawyl (Hautes Alpes calcaires de Suisse occidentale), matières dissoutes et en suspension emportées par les sources
Wildberger, A.
Abstract:
HIGH ALPINE KARST OF RAWYL (SOUTHWESTERN SWITZERLAND): DISSOLVED AND SUSPENDED MATERIALS IN THE WATER OF KARSTIC SPRINGS - The karst of the Rawyl area is located between 1200 and 3250m elevation, at an average height of 2500m. The mean annual rainfall is about 2m. The output of dissolved and suspended material was measured at various important springs, subjected to a glacial to nivo-glacial discharge pattern. The dissolution rate is around 0,06 to 0,075 mm/year of which 1 to 25% are suspended materials, the rest being transported under dissolved form. The flushed material does not correspond exactly with the lithology of the aquifer: for the dissolved material, Mg is in excess compared to the Mg in the carbonates (exchange of cations Ca-Mg); for the suspended material, the clay minerals clearly out-weight the quartz (selection by different sizes and forms).
