Source-Bordering Dune

Living reference work entry


There is no formal definition, and source-bordering dunes (SBD) are not listed in the Encyclopedia of Geomorphology (Goudie 2004). The term SBD generally describes a dune closely bordering the leeside of its sediment source (Page et al. 2001), but more specifically, it has been applied to sand dunes downwind of sand bed rivers (Page 1971; Bullard and McTainsh 2003).


Lee-source dune, or umbrafon dune (Melton 1940); Source-bordering loess dune (Stone 1967); Source-bordering rampart (Wopfner and Twidale 1988); Riverine dune (Ivester and Leigh 2003)

A type of dune


SBDs develop from deflation out of a sediment source and deposition parallel to its margin resulting in dune forms, which are oriented transverse to the main wind direction (Bullard and McTainsh 2003).


Three subtypes of SBDs are distinguished depending on the sedimentary environment of the source region:
  1. (1)

    Riverine (fluvial, Fig. 1; Page et al. 2001)

  2. (2)

    Lunette(lacustrine; e.g.,...
