The action of a fluid moving over a mobile surface often generates bedforms which in turn influence the flow and how particles are transported. On Earth, bedforms are found in many environments: deserts, rivers, estuaries, continental shelves, deep seas, volcanic regions and glacial environments. Bedforms have also been observed in extra-terrestrial environments, such as on Mars and Venus.
Understanding the links between flow, particle transport, and bedform morphodynamics and stratigraphy is of interest for a wide range of applied and fundamental research. For example, this knowledge is used to manage contemporary environments, such as rivers and coastal seas. Recently, the societal relevance of bedform research has been highlighted, as bedforms are shown to interact with offshore structures. Furthermore, bedform morphology and sedimentology can provide insights into fluid movement across modern and ancient, otherwise unknown, landscapes.
This session aims to highlight many aspects of the complex interaction between flow, sediment transport, stratigraphy and bedforms in terrestrial and planetary environments. The session welcomes contributions from theoretical, field, laboratory and numerical approaches related to bedforms found in aeolian, shallow and deep waters, glacial and planetary environments. The session intends to advance our knowledge of how to decipher information contained in terrestrial and extra-terrestrial bedforms and help foster fruitful discussions on understanding bedform morphodynamics and stratigraphy.
