Abstract

An investigation of the modification of airflow by a discrete, semi-circular roughness element (in this case, vegetation) is presented. The 3-dimensional flow structure about the vegetation is dominated by horizontal separation characterized by symmetrically opposed reversing vortices which form within a triangular wake. A vertical separation envelope is also formed over the vegetation. Pyramidal shadow dunes are formed within this flow structure when aeolian sand transport occurs.-from Author
