Dr Arved Schwendel

My research interests are in fluvial geomorphology, hydrological processes within a catchment and stream ecology. I focus in particular on sediment fluxes in a changing environment, conveyance of sediment from slopes through the fluvial system, river channel migration and floodplain evolution.

I also have a strong interest in interdisciplinary research on river-floodplain interactions, eco-hydraulics and the effects of fluvial processes on lotic ecosystems.

I regularly work on environmental consultancy contracts in the areas of topographical and geophysical surveying and river restoration.
