Near-natural bypass channel development : focus on a highly dynamic river reach in the MONDAU project area between Neuburg and Ingolstadt

Kurzfassung/Abstract

Features for functional rivers are well known, but self-development forecasts and minimum standards are still unsatisfactory. But running water, at any given location, can no longer be managed without an active understanding of the drivers and impacts of the three other elements: sediment and bedload, fish and benthos, vegetation (plants and deadwood). Without a sound knowledge of the structures and biocoenosis of semi-natural streams it is not possible to properly assess degraded streams or to plan their successful “restoration”.
To support the understanding of fluvial eco-hydromorphological process dynamics, point clouds (derived from the terrestrial laser scanner) and ortho-photomosaics (derived from unmanned aerial vehicles) are used as a basis for mapping.
