Transport of Sand and Partly Cohesive Sediments in a Circular Pipe Run Partially Full

Abstract

Many sediment deposits contain not only a granular but also a mineral and/or organic cohesive fraction, which has the potential to change significantly the erosion response when compared to noncohesive sediment deposits. Sediment deposits containing a low proportion of cohesive sediment display a specific, transitional behavior between cohesive and noncohesive sediments. In the past, several studies have examined partly cohesive sediment, however, the quantification of its erosion behavior is still unsatisfactory. In an attempt to advance the understanding and qualitative description of erosion and transport of mixed sediments in pipes, a comprehensive experimental investigation on the erosion behavior was designed. Tests were conducted in a flume with semicircular cross section with a diameter of
