Research interests

Recent and current topics of the ICP's dune group include collisions of Barchan (crescent-shaped) dunes, transformation of dune shapes in the presence of vegetation and formation of Barchans and transverse dunes from a sand bed.

Orencio Durán and Hans Herrmann of the University of Stuttgart in Germany developed their equations using scientific observations of sand-dune behaviour in desert regions. The two devised a mathematical model describing how and under what conditions a migrating dune, known as a barchan dune, can be turned by vegetation into an inactive parabolic dune, a dune that stays put. The dune behaviour predicted by their model fits well with what has been observed in nature and also gives a way of predicting who wins the battle in a given circumstance — plant or sand.
