  • 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.

  • The impact of climate on the discharge of the River Rhine
  • In this book a first attempt has been made to provide a more detailed, quantitative assessment of the sensitivity of the River Rhine discharge to climate change. The attempt indicates the order of magnitude of the effect of a climatic change
  • . In this respect the sensitivity of the river has been analysed, a spatially distributed water balance model has been developed and finally discharge scenarios are assessed. - (AGD)

  • Holocene paleofloods of the Ross River, Central Australia
  • The AA. describe the alluvial stratigraphy of a central Australian river downstream from its headwater drainage area and at the point where it exists from its gorge section on to a broad floodplain. They also illustrate how that stratigraphy can
  • be used to identify the effects of large prehistoric floods on river morphology.

  • Valleys and river benches from the viewpoint of morphotectonics
  • The geomorphological concepts on the formation of valleys and river benches applied until now have been based upon the viewpoints of dynamic and climatic geomorphology. This exogenous interpretation should be abandoned and an endogenous concept

  • Formation of river terraces and evolution of drainage system in the middle reaches of the Yellow River
  • On the basis of field data and by paleosol-dating method, it is concluded that the Yellow River of this segment and its main tributaries were formed 1670-1450 ka ago, afterwhich six terraces and two valley flats have developed. The evolution

  • A study of long term environmental effects of river regulation on the Yellow River of China in historical perspective
  • Through an analysis of both the historical and the present-day processes, an effort has been made to deal with the long-term environmental effects induced by man's regulation of the Yellow River of China, which was started more than 2,000 years ago.

  • Influences of relative sea-level rise and Mississippi River Delta plain evolution on the Holocene Middle Amite River, Southeastern Louisiana
  • The Holocene geomorphic history of southeastern Louisiana's middle Amite River is recorded in the stratigraphy of three alloformations, identified in decreasing age as the Watson (WAT), Denham Springs (DS), and Magnolia Bridge (MAG). Base-level
  • influences of the relative sea-level rise and the Mississippi River delta plain were so dominant that the effects of possible climate change were not recognized in the Holocene Amite River system.

  • The real river that runs through it : Montana's imperilled Blackfoot
  • The A. exposes the geographic myth behind a recent Hollywood film. Unrelenting resource extraction and toxic pollution have turned the Blackfoot River of Western Montana into an ecological disaster. - (DWG)

  • Tubing on the Apple River: a new industry ?
  • The Apple River in northwest Wisconsin, USA, has become popular as a place to float downstream in the clean water on rubber tubes. A new recreational activity has had a significant economic impact on the local area. - (DWG)

  • Holocene river alluviation in Britain
  • Episodes of regional and country-wide Holocene alluviation in British river basins are identified using information from 59 published sites that extend from northern Scotland to the south coast of England. Widespread synchrony of Holocene fluvial
  • episodes in Europe and USA, particularly over the last 5000 years, suggests that climate may have more directly controlled sedimentation and erosion in British rivers than hitherto been believed. Although prehistoric and historic forest clearance

  • Fluvial terraces of the lower Susquehanna River
  • Within the context of the new age control, the purposes of this paper are to: 1) identify, map and correlate fluvial terraces along the lower Susquehanna River; 2) assign ages to the terraces by downstream correlation to the fluvial stratigraphic
  • seequence at the river mouth; 3) develop a model for terrace genesis on a U.S. Atlantic-type passive margin; and 4) suggest the nature, magnitude, and rates of passive margin deformation.

  • Geomorphic observations of rivers in the Oregon Coast Range from a regional reconnaissance perspective
  • This paper presents the results of examining some aspects of river morphometry in Western Oregon to better understand the geologically recent history of Pacific-plate subduction. Changes in long profile, gradient, gradient index, pseudo-hypsometric
  • integral, valley incision, and sinuosity fractal dimension were studied. All data were gathered from topographic quadrangles and geologic maps, and so the results are limited to the description of river forms with only limited interpretations.

  • This paper describes meandering alluvial rivers with mean annual suspended-sediment concentrations of more than 100 kg m-3 on the Loess Plateau, China, and explains their formation as caused by the effect of hyperconcentrated water flow. When
  • the river is dominated by hyperconcentrated flow, the rate of energy expenditure required for sediment transport declines significantly. Accordingly, the river channel adjusts itself to a lower channel gradient by increasing the river length, resulting
  • in a meandering channel. The paper also discusses the conditions for the discriminations of meandering and braided rivers in this area.
