  • field. High-frequency velocity measurements obtained using an array of electromagnetic current meters are combined with results from grid and transect sampling of bed sediments from 9 sites on 3 small upland rivers in N. Exmoor, U.K.
  • The purpose of this paper is to clarify several aspects of the sedimentology of riffle-pool sequences, and to suggest how these both reflect and control riffle-pool stability in the presence of spatial differences in the turbulent near-bed flow

  • Bed configuration and microscale processes in alluvial channels
  • The research questions discussed in this article are central to the understanding of fluvial processes in both sand- and gravel-bedded rivers. Prominent research themes are identified. The first is the use of fractal concepts in the study of fluvial
  • processes. The second is the study of turbulent flow structures. Finally, this review clearly focused on bed microtopography and related flow turbulence and sediment transport processes.

  • Morphological development of longitudinal profiles of rivers in Japan and Taiwan
  • Alluvial cone ; Earth surface processes ; Fluvial processes ; Island arc ; Japan ; Longitudinal section ; River bed ; Taiwan ; Tectonics
  • The rivers in Japan and Taiwan lying in a warm-humid climatic region and on island arcs with violent crustal movement have markedly large erosion rates and are today not at grade. Nevertheless most of the longitudinal profiles of the rivers
  • are described by either exponential or power functions, both of which have been proposed for graded rivers. Using the coefficients of the functions best fitting to the longitudinal profiles, the stages in morphological development of the profiles are discussed

  • River response to channel regulation: case study of the Raba River, Carpathians, Poland
  • This paper is a case study of the changes in the Raba, a mountain gravel-bed river, which have followed its channel regulation during the present century, especially in the last 40 years. The paper has two main aims: 1) to show the complex nature
  • of the mechanisms involved in approaching a new equilibrium; and 2) to discuss disadvantages of the applied regulation scheme being revealed on the catchment and regional scales, and to utilize them as a geomorphological lesson for river engineering.

  • This paper discusses a relatively new field method that may be useful to monitor the suspended transport balance, and presents findings from a trial application of the method in a large sand bed river. The data were collected in a 10 m deep channel
  • of the Fraser River near Mission, British Columbia, Canada.

  • A characterization of the geomorphologic conditions of the Ohře river valley in the neighbourhood of Doupov mountains. The terrace system and the slope conditions of the river bed in relation to the morphostructure and genesis of the relief
  • . The Ohře river valley in the neovolcanic Doupov mountains has been originated in Miocene in a zone of tectonic bend between the basalt lava streams of the stratovolcan centre and volcanic bodies in the northern rim. - (MS)

  • The aim of this paper is to describe steep mountain streams in terms of bed morphology, sediment features and sediment transport processes. Field data and observations from Mid-Wales and Eastern Alps streams are reported. Channel morphology

  • Anastomosing rivers are characterized by multiple channels separated by islands excised from the floodplain. Their status relative to the continuum concept of channel pattern is assessed with channel pattern defined in terms of three variables: flow

  • River terrace development by concurrent fluvial processes and climatic changes
  • diameter of terrace sediments, paleo-tractive forces were evaluated based on the correlations between tractive force and grain diameter of the sediment on the present river bed. The valley filling was caused by the diminution in tractive force related
  • Along the Usui River in central Japan, three well-developed terrace levels are observed. To clarify the response of fluvial systems to climatic change, terrace sediments were interpreted from the viewpoint of paleohydraulics. Using the grain

  • sedimentology of anastomosed and wandering gravel-bed rivers. The scale problems of facies analysis may be overcome by employing architectural element analysis in conjunction with modern geophysical methods such as shallow reflection seismology and ground
  • Canadian river scientists made significant contributions to the early development (1960-80) of fluvial facies models, particularly to those for braided rivers. More recent Canadian studies (1980-92) have centred on understanding the facies

  • The channel gradients, along three rivers in coastal northern California, discussed in this paper are higher than those often reported for channels with pool-riffle, rather sequences. However, the AA. have designated these as pool-riffle, than step
