Sediment archives in the terrestrial and marine realm are regularly analyzed to infer
changes in climate, tectonic, or anthropogenic boundary conditions of the past. However …

River bed sediments typically fine downstream, where fining of median grain sizes are often
described as exponential, except where fine gravel abruptly transitions to sand. Across the …

Abstract The Gangetic Plains comprise steep gravelly river channels that transition to low
gradient sandy channels 10-40 km downstream of the mountain front. This “gravel-sand …

The transport and deposition of mud in rivers are key processes in fluvial geomorphology
and biogeochemical cycles. Recent work indicates that flocculation might regulate fluvial …

Whether permafrost systematically alters the rate of riverbank erosion is a fundamental
geomorphic question with significant importance to infrastructure, water quality, and …

The geochemical and physical properties of terrigenous sediment stacked in sedimentary
basins are used as proxies for the paleo-environmental conditions that prevailed during their …

River bed sediments often lack fine gravel between 1 and 5 mm, a phenomenon referred to
as the “grain size gap.” The gap corresponds to the rapid reduction in grain size associated …

An abrupt transition in bed grain size occurs in river systems. Over a short downstream
distance, often only a few channel widths, the bed surface fines from gravel (∼ 10 mm) to …

Flood hazard maps used to inform and build resilience in remote communities in the Terai
region of southern Nepal are based on outdated and static digital elevation models (DEMs) …

A unique synthesis of grain size-distance data is presented, comparing, for the first time,
grain size and fining trends in a wide range of modern and ancient axial sediment dispersal …
