Vegetationens roll i erosiva vattendrag por Leth, Malin

“…I have therefore studied 17 articles concerning vegetation and erosion control, which were found in different databases such as: Web of Knowledge, Biological Sciences, Academic Search Elite and Google Scholar. The articles were then analysed and formed to a theoretical model, which was applied on a field study of two key areas facing erosion in a river bank; Rönne å, Ängelholm municipality, Sweden. …”
