Geomorphology in Borås-Kinna-Ulricehamn area, southwestern Sweden
Abstract
A geomorphological map of southwestern Sweden is presented in this thesis. 12 different landforms were mapped using a 2 m resolution digital terrain model from LiDAR. The focus of the map is on glacial geomorphology however two non-glacial landforms were also included. Two former ice-dammed lakes were also reconstructed in this project, they were estimated to have lasted between 95-135 and 70-100 years respectively. The glacial landforms found in the study area reveal a deglaciation likely governed by an active warm-based glacier. Glacial lineations indicate ice flow direction towards the southwest. The hummocks in the region where often found in connection with eskers, some of the hummocks appear to be lying on top of the eskers while others appear overlain by eskers. This could imply multiple processes behind the formation of hummocks. Lastly the most common trends for the fracture valleys were between NNE-SSW to ENE-WSW.
