  • Fluvial geomorphodynamics in the Danube River valley and tributary river systems near Regensburg during the Upper Quaternary. Theses, questions and conclusions
  • This paper highlights the most important results of detailed investigations in the Danube River Valley, east of Regensburg. For the hydrological important characteristics of the different river systems, refernce is made to the original thesis
  • Holocene river and slope dynamics in the Black Forest and Upper Rhine Lowlands under the impact of man
  • The investigations on the Holocene river activities and slope dynamics in the Black Forest and Upper Rhine Lowlands were carried out with geomorphological mehods. They include the analysis of sediments, the radiocarbon dating of organic material
  • of changes on the river development, which were induced by man and/or climate since Neolithic ages.
  • The development of the middle and lower course of the Weser river during the Late Pleistocene
  • After the retreat of the glacier of the Drenthian-1 advance the Weser River cut a new path northwards to the Magdeburg-Bremen meltwater channel. The pebbles in gravel in samples taken from 99 boreholes up to 50 m deep were analyzed to distinguish
  • A 20 years investigation of central European rivers covering the Alpine foreland, the central upland and the northern lowland resulted in a system of the fluvial facies, the textures of fluviatile terrace bodies and different terrace patterns
  • . Synchronous phases of alternating increased fluvial activity and quiescence on major and smaller rivers give proof of climatic control over the fluvial rhytmicity. Despite regional and human modification, the natural imprints remain visible and dominating.
  • Temporal and spatial variation in dissolved and solid load years in partial catchment areas of the upper Leine river (southern Lower Saxony)
  • Sedimentary behavior of the alpine Ruetz River (Stubai Valley, Tyrol, Austria) in historical times
  • in an untamed mountain torrent. These results may be used to formulate a probability model describing the movement of single coarse particles on the river bed. The individual step lengths are best described by a two-parameter gamma distribution and the rest
