Morphological properties of two-dimensional and three-dimensional bedforms in open channel flow: A flume experiments study

open access: yesInternational Journal of Sediment Research
Bedforms are formed by sediment particles under the action of flow, which in turn affect flow and sediment movement. However, the fundamental mechanisms behind the formation and development of bedforms under varying flow conditions, the interconnection ...

Bounding Surfaces in a Barchan Dune: Annual Cycles of Deposition? Seasonality or Erosion by Superimposed Bedforms?

open access: yesRemote Sensing, 2019
A barchan dune near Tarfaya in Morocco has been surveyed using ground-penetrating radar (GPR) revealing packages of dipping strata within the dune that are truncated by bounding surfaces. The bounding surfaces dip in the downwind direction, truncate sets

Measuring (subglacial) bedform orientation, length, and longitudinal asymmetry - Method assessment.

open access: yesPLoS ONE, 2017
Geospatial analysis software provides a range of tools that can be used to measure landform morphometry. Often, a metric can be computed with different techniques that may give different results.

Occurrence of storm-generated bedforms along the inner continental shelf: Southeastern Brazil

open access: yesBrazilian Journal of Oceanography, 2010
Side-scan sonar surveys were carried out in two different areas on the inner continental shelf off the state of EspĂ­rito Santo (southeastern Brazil, Area 1- Guarapari Inner shelf -GUA and Area 2- Espirito Santo Bay - BES) and revealed bedforms much like ...

Evidence of bedform superimposition and flow unsteadiness in unit-bar deposits, South Saskatchewan River, Canada

open access: yes, 2011
Unit-bar deposits are ubiquitous components of river-channel deposits and strongly influence their hydrological properties, yet they are not easy to interpret.

Literature Review of Unconsolidated Sediment in San Francisco Bay and Nearby Pacific Ocean Coast

open access: yesSan Francisco Estuary and Watershed Science, 2009
A review of the geologic literature regarding sedimentation in the San Francisco Bay estuarine system shows that the main part of the bay occupies a structural tectonic depression that developed in Pleistocene time. Eastern parts, including San Pablo Bay

In-situ sedimentary evidence of complex bottom currents at a modern deepwater seamount

open access: yesCommunications Earth & Environment
Interactions between deep-ocean currents and seafloor sediments create bedforms that are important for paleoenvironment reconstructions, resource exploration, and mapping ecosystems.
