The rivers of the world are undergoing accelerated change in the Anthropocene, and need
to be managed at much broader spatial and temporal scales than before. Fluvial remote …

Earth's terrestrial topography evolves in response to the interaction of tectonics, climate, and
lithology. Recent discoveries suggest that the grain size of sediments produced on hillslopes …

Bed load sediment transport, in which wind or water flowing over a bed of sediment causes
grains to roll or hop along the bed, is a critically important mechanism in contexts ranging …

The timing and mode of deposition for Martian regolith breccia Northwest Africa (NWA) 7034
were determined by combining petrography, shape analysis, and thermochronology. NWA …

Sediment grain size links sediment production, weathering, and fining from fractured
bedrock on hillslopes to river incision and landscape relief. Yet models of sediment grain …

The properties of sediment grain shape provide valuable information about the transport
mechanisms in different sedimentary and geomorphological environments. With the …

Several studies focused on the role of rivers as vectors of microplastics (MPs) towards the
sea. It is well known that during their path through the fluvial environment, MPs interact with …

Testing long-term properties of aggregates requires time consuming laboratory tests.
Alternatively, mathematical models can also be used to describe the abrasion process of …

The discovery of remarkably rounded pebbles by the rover Curiosity, within an exhumed
alluvial fan complex in Gale Crater, presents some of the most compelling evidence yet for …

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 …
