Erratum for “Bedform Spacing and Flow Resistance”

Bedform Dynamics and Mine Burial

Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...

River bedform inception by flow unsteadiness: A modal and nonmodal analysis.

River bedforms arise as a result of morphological instabilities of the stream-sediment interface. Dunes and antidunes constitute the most typical patterns, and their occurrence and dynamics are relevant for a number of engineering and environmental applications. Although flow variability is a typical feature of all rivers, the bedform-triggering morphological instabilities have generally been s...

Bedform climbing in theory and nature

Where bedforms migiate during deposition, they move upward (climb) with respect to the generalized sediment surface. Sediment deposited on each lee slope and not eroded during the passage of a following trough is left behind as a cross-stratified bed. Because sediment is thus transferred from bedforms to underlying strata, bedforms must decrease in cross-sectional area or in number, or both, un...

Erratum: Acquired antibiotic resistance genes: an overview

Dr. Marilyn C. Roberts and Dr. Stefan Schwarz have contacted the authors of the original publication with several comments and suggestions to better harmonize the correct nomenclature of the antibiotic resistance genes, as the gene names were not always correctly presented in the various tables given. Authors often pick their own gene names which in many cases have been approved for use for oth...
