In present-day alluvial environments, the impact of vegetation on sedimentological processes and deposits is well known. A vegetated catchment may decrease sediment yield, sediment erodibility, Hortonian overland flow, aeolian winnowing of fines, the proportion of sediment transported as bedload, and may increase bank stability, infiltration into substrates, and bed roughness.

Mudrocks such as slate and shale are rarely found in stratigraphy older than about 500 million years. McMahon and Davies compiled a large database of mudrock occurrence over the past 3.5 billion years to help assess the origin of this ubiquitous rock type (see the Perspective by Fischer). Mudrocks appeared at the same time as did deep-rooted land plants.

An alluvial damper was a subsystem of a starship's hyperdrive that was responsible for the regulation of thrust output from the generator. It operated by moving a servomotor-controlled plate to channel the emission of ion particles from the hyperdrive in a certain direction.. Han Solo once resisted a temptation to convert C-3PO into a pair of backup alluvial dampers.
