  • Suspended sediment load estimation and the problem of inadequate data sampling : a fractal view
  • Fractals ; Mississippi ; Missouri ; Model ; Sampling ; Statistics ; Stream ; Suspended load ; United States of America ; Watershed
  • Use the notion of fractal theory to obtain important information regarding the possibility of temporal transformation of sediment load data is the subject of this study. As a first step, daily suspended sediment load data observed in the Mississippi
  • behaviour in the suspended sediment load data, suggesting the possibility of transformation of data from one scale to another using a multi-dimensional model.

  • Relationship between suspended sediment load, channel geometry and land area increment in the Yellow River Delta
  • Channel geometry ; China ; Delta ; Environmental management ; Huang He ; Human impact ; Hydraulic works ; Sediment transport ; Stream ; Suspended load
  • The aims of this work are : to determine what is the critical suspended sediment load needed in order to maintain the land balance of the Yellow River Delta for 2 periods before and after 1976 (the last time the channel shifted); and to examine
  • the variation in the channel geometry and gradient in response to changes in sediment load and delta area at the river mouth. These results are of importance for the management of the lower Yellow River channel and the delta.

  • A bed-load transport model for rough turbulent open-channel flows on plane beds
  • Data from flume studies are used to develop a model for predicting bed-load transport rates in rough turbulent two-dimensional open-channel flows moving well sorted non-cohesive sediments over plane mobile beds. The object is not to predict
  • transport rates in natural channel flows but rather to provide a standard against which measured bed-load transport rates influenced by factors such as bed forms, bed armouring, or limited sediment availability may be compared in order to assess the impact
  • of these factors on bed-load transport rates.
