Predicting wind velocities from sand dune and draa spacings determined by Fourier analysis in Interpretation of windflow characteristics from Eolian landforms.
The spacing of sand dunes and draas (dune groups) is one parameter that can be used to estimate wind velocity and available wind power. Measurements of spacings can be made directly from LANDSAT imagery or aerial photography. Fourier analysis
of these measurements reveals the predominant spacings. Assuming that shear velocity is the dominant factor determining the wave leugth of bedforms, the spacing can be used to compute the threshold shear velocity using mathematical relationships derived by Wilson (1972
