Abstract Sediment Routing Systems (SRS) and Sediment Generation (SG) are two branches
of sedimentary geology which are complementary, although their full integration remains …

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 …

Untitled Page 1 Page 2 GEOMORPHOLOGY OF DESERT DUNES Sand dunes cover up to a
quarter of many desert regions. Determining the factors that determine their shape, size and …

Rivers are important agents of change that shape the Earth's surface and evolve through
time in response to fluctuations in climate and other environmental conditions. They are …

This cutting-edge summary combines ideas from several sub-disciplines including geology,
geomorphology, oceanography and geochemistry to provide an integrated view of Earth …

We compiled a data set of 541 bankfull measurements of alluvial rivers (see supporting
information) and used Bayesian linear regression to examine empirical and theoretical …

River-bed sediments display two universal downstream trends: fining, in which particle size
decreases; and rounding, where pebble shapes evolve toward ellipsoids. Rounding is …

Wind‐blown sand and dust models depend sensitively on the threshold wind stress.
However, laboratory and numerical experiments suggest the coexistence of distinct fluid and …

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 …

Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at
predictable wavelengths and growth rates. As dunes mature and coarsen, however, their …
