Some Aspects on Fluvial Sediments and Fluvial Morphology I. General Views and Graphic Methods

ABSTRACT

This article is the first in a series of articles dealing with fluvial sediments and fluvial morphology and accounting for results of field research, experimental investigations and theoretical analyses conducted at the Geomorphology Laboratory in Uppsala. After some general statements about the relation between processes, sediments and morphology, the state of sediment movement is discussed, particularly the influence of grain size and density on the transport processes. In the last part of the article some graphic methods for describing the grain size distribution are presented. These methods are particularly useful when discussing the depositional environment of suspended sediments and will find a practical application in a succeeding article in this series.
