Glupförekomster i UppsalaområdetHagström, Per January 2012 (has links)
One special feature in the Swedish nature, mainly in the county of Uppland is one distinctive kind of dip, which can be distinguished from its fast and unaccounted drainage. These dips are called “glupar” and can mainly be found in coarse-grained pebbled moraine under the highest shoreline (HK). During spring, and particularly when snowmelting occur, the wateramliptude fluctuates a lot until late summer or the beginning of fall comes; these dips are then often almost fully drained. During winter however, the waterlevel stands high. Therefore, “glupar” can for some time be falsely interpreted as a small pond. Areas around Jumkil just outside Uppsala are charaterized for their large amount of these kinds of dips. The origin of “glupar” is poorly studied or described through the literature, which to a large extent is the main reason for this study.
