Extant, planform-based facies models for alluvial deposits are not fully fit for purpose,
because they over-emphasise plan form whereas there is little in the alluvial rock record that …

Volcaniclastic sediments, broadly defined as clastic deposits derived from the transport,
deposition and/or redeposition of the products of volcanic activity, have long been a …

Supercritical‐flow phenomena are fairly common in modern sedimentary environments, yet
their recognition and analysis remain difficult in the stratigraphic record. This fact is …

There is growing recognition that sedimentary deposits related to high-energy, large-scale,
freshwater floods are widespread across the continents and, in the main, can be related to …

The preservation of bedforms related to supercritical flows and hydraulic jumps is commonly
considered to be rare in the geologic record, although these bedforms are known from a …

The very largest glacier outburst floods have been termed 'megafloods' given their volume
and peak discharge. That definition might be revised because those floods have become …

At least six glaciations are purported to have affected North Africa and the Middle East
region over the last one billion years, including two in the Cryogenian (Neoproterozoic) …

Extreme flood events have the potential to cause catastrophic landscape change in short
periods of time (100 to 103 h). However, their impacts are rarely considered in studies of …

Upper‐flow‐regime bedforms, including upper‐stage‐plane beds, antidunes, chutes‐and‐
pools and cyclic steps, are ubiquitous in glacigenic depositional environments characterized …

Lahars represent some of the most dangerous phenomena in volcanic areas for their
destructive power, causing dramatic changes in the landscape with no premonitory signs …
