River dams provide many benefits, including flood control. However, due to constantly
evolving channel morphology, downstream conveyance of floodwaters following dam …

Clinoforms are ubiquitous depositional surfaces in sedimentary systems. The quintessential
shape, with a flat or gentle topset, sloping foreset, and gentle to flat bottomset, is …

The dunes that cover the beds of most alluvial channels change in size and shape over time
and in space, which in turn affects the flow and sediment-transport dynamics of the river …

Dunes form critical agents of bedload transport in all of the world's big rivers, and constitute
appreciable sources of bed roughness and flow resistance. Dunes also generate …

River dunes are wavelike features in sandy riverbeds that move slowly in a downstream
direction. These bedforms are shaped by the interaction between flowing water and sand …

The Curiosity rover is exploring Hesperian-aged stratigraphy in Gale crater, Mars, where a
transition from clay-bearing units to a layered sulfate-bearing unit has been interpreted to …

Sinuous ridges are important landforms on the surface of Mars that show promise for
quantifying ancient martian surface hydrology. Morphological similarity of these ridges to …

The low temporal completeness of fluvial strata could indicate that recorded events
represent unusual and extreme conditions. However, field observations suggest that …

Trains of secondary bedforms, superimposed on primary dunes, have been observed in
rivers worldwide. To date, it has remained unclear how these secondary bedforms affect the …

River dunes, dynamic bedforms in the river bed, limit navigable depths during low flows and
increase bed roughness. To predict the navigable depth or where maintenance dredging is …
