Abstract
A survey program is described which utilizes laboratory simulation of the relevant wind characteristics in a meteorological wind tunnel. To evaluate the validity of laboratory simultation methods and provide a confidence measurement bound for laboratory data, a limited field measurement program was simultaneously conducted. In this study both terraced and contoured models of the Rakaia River Gorge region were prepared to an undistorted geometric scale of 1:5000. The contoured model was examined for three separate surface roughness conditions: a surface textured to represent typical paddock grass roughness only, the same surface with zero-porosity shelterbelts added, and the same surface with porous shelterbelts added.Keywords
