Abstract

This study proposes a useful alternative visual technique to characterize the surface substrate (size and distribution) over an expanse of a gravel-bed river. The paper is divided into 4 sections : a brief review of bed sediment sampling techniques; an explanation of the methodology and training protocol used for the visual estimation of a river bed surface sediment size distribution; the error estimation linked to this technique and a comparison with common surface sampling techniques (grid sampling and surface-bulk sampling); and a discussion of the applicability and some advantages of the proposed visual characterization technique
