Fluvial Research Group
In the Fluvial Research Group we study riverine systems in order to better understand  the processes acting within catchments and in river channels. Our research concentrates on past, present and future river dynamics. In addition to open water processes, we focus on influence of ice cover on river behaviour as well. We are especially interested in changing river environments and in how human interaction with these systems affects natural processes, leading to changes e.g. in flow regimes and erosion-sedimentation processes. In order to advance river research we develop new methods in river surveying, channel morphology-, hydraulic- and watershed-modelling. 
Methodologically, we focus on laser scanning, sediment transport sampling, mobile current profiling and bathymetric modelling. In addition to our main research focus on the sub-arctic, we also work in Spain, the USA and Iceland. main_page_4.jpg
