TL;DR: In this paper, the authors report on successful laboratory experiments that elucidate flow structure in one constant-width bend and a second bend with an outer-bank widening, with both a flat immobile gravel bed and mobile sand bed with dominant bedload sediment transport.

TL;DR: In this paper, the authors provide an overview of the processes involved in the maintenance and adaptation of dunes, and provide new tools for the analysis of dune dynamics, and applies these to a series of bespoke experiments.

TL;DR: In this article, a laboratory flume experiment was performed to investigate the time development of scour around a vertical cylinder acting as a scaled model of an offshore wind turbine monopile in tidal currents.

TL;DR: In this article, the authors study groundwater seepage from a distant source of groundwater and from infiltration of local precipitation in a series of sandbox experiments and combine their results with previous experiments and observations of the Martian surface.

TL;DR: In this article, a combined approach with experiments and numerical modeling was used to examine outflow processes that result from pressurized groundwater in Mars, where the authors used a large sandbox flume, where they applied a range of groundwater pressures at the base of a layer of sediment and compared the results to discharge estimates based on previous morphological studies and showed that groundwater seepage and fissure outflow are insufficient to explain the formation of large outflow channels from a single event.
