Experimental Investigations of Sandy Riverbed Morphology

Contemporary advances in experimental methods and technologies are facilitating new and valuable insight into research questions of long standing. Following a review of the history of investigations regarding sandy riverbed morphology, this chapter presents a series of recent investigations into outstanding gaps in understanding of fluvial bedforms. Equipment advances are highlighted in terms of use of a viscous-fluid flume, a water tunnel, an induction power transfer (IPT) carriage, a custom-built particle image velocimetry (PIV) system, a 3D laser scanner, and a flying-probe measurement system. Advances in understanding of fluvial bedforms arising from these investigations are also presented.
