- A
bedform is a
geological feature that
develops at the
interface of
fluid and a
moveable bed, the
result of bed
material being moved by
fluid flow. Examples...
- cross-strata. Cross-bedding
forms during deposition on the
inclined surfaces of
bedforms such as
ripples and dunes; it
indicates that the
depositional environment...
- An
antidune is a
bedform found in
fluvial and
other channeled environments.
Antidunes occur in
supercritical flow,
meaning that the
Froude number is greater...
-
varying speeds and
velocities produce different structures, are
called bedforms. In the
lower flow regime, the
natural progression is from a flat bed,...
-
Cyclic steps are
rhythmic bedforms ****ociated with
Froude super-critical flow instability. They are a type of
sediment wave, and are
created when supercritical...
- Hall, Minard; Ramón, Patricio; Dingwell,
Donald B. (2013-10-13). "Dune
bedforms produced by
dilute pyroclastic density currents from the
August 2006 eruption...
- In geology,
ripple marks are
sedimentary structures (i.e.,
bedforms of the
lower flow regime) and
indicate agitation by
water (current or waves) or directly...
- such as ripples, dunes, or
antidunes on the
river or
stream bed.
These bedforms are
often preserved in
sedimentary rocks and can be used to
estimate the...
-
characteristic of
turbidity currents. The
surface of a
particular bed,
called the
bedform, can also be
indicative of a
particular sedimentary environment. Examples...
- next
blows in the
dominant direction.
Draas are very large-scale dune
bedforms; they may be tens or a few
hundreds of
metres in height,
kilometres wide...
