Over the last decades, large-scale underwater flow-transverse bedforms have been named by a range of terms such as dunes, sand waves, megaripples, antidunes, cyclic steps or sediment waves. However, it is sometimes not clear if these names are describing intrinsically different bedform types or if differences arise from other reasons (for example habits in specific research communities). Furthermore, the parameters used to describe bedform properties are not harmonised so far.

We would like to produce a reference which compares the different types of large-scale underwater flow-transverse bedforms and discusses how to best describe them in a way which is coherent and useful for other researchers. In order to do this, we have created a short survey to collect the opinion, experience and thoughts of researchers from various communities and backgrounds. Our aim is to write a paper which addresses at best the needs and thoughts of the different communities. It would be really great if varied scientists answered the survey. It should take around 10 to 15 min to complete it.
