▪ Abstract This is a review of the mechanisms that control neutrally stable turbulent boundary-
layer flow over hills and waves, their relative magnitudes, and how they exert their greatest …

Abstract The Askervein Hill project was a collaborative study of boundary-layer flow over low
hills carried out under the auspices of the International Energy Agency Programme of R & D …

It is more than half a century since the publication of RA Bagnold's classic book The physics
of blown sand and desert dunes, and it is a tribute to the quality of Bagnold's work that many …

We review developments in the field of boundary-layer flow over complex topography,
focussing on the period from 1970 to the present day. The review follows two parallel …

A general analysis is developed for turbulent shear flows over two‐and three‐dimensional
hills with low‐slopes which allows for a wide range of upwind velocity profiles, such as those …

We investigate the changes to a fully developed turbulent boundary layer caused by the
presence of a two-dimensional moving wave of wavelength L= 2π/k and amplitude a …

We present an analysis of data from a measurement campaign performed at the Bolund
peninsula in Denmark in the winter of 2007–2008. Bolund is a small isolated hill exhibiting a …

Field measurements on an unvegetated, 10 m high barchan dune in Oman are compared
with measurements over a 1: 200 scale fixed model in a wind tunnel. Both the field and wind …

Abstract In 1975 Jackson and Hunt observed that there had, until that time, been few
attempts to relate measurements of wind velocity on hills to the local topography. The …

Laser-Doppler measurements of velocity characteristics are reported for the recirculating
flow established in the wake of two-dimensional, polynomial-shaped obstacles that are …
