Abstract A wind-tunnel study of the roughness effect of a network of uniformly spaced long parallel windbreaks has been attempted. The roughness parameterZ 0 in the well-known logarithmic profile has been obtained as a function of the ratio of the spacingL to heightH of the barriers. In one part of the study, a naturally developing boundary layer was used and the windbreaks were not spread on the entire wind-tunnel floor. Spacing ratiosL/H of 1 to 20 were treated. In the other part of the study, spires were used to thicken the boundary layers artificially and the windbreaks were spread throughout the wind-tunnel floor. In this case, spacing ratiosL/H of 1 to 30 were examined. Values of the roughness parameter obtained from the above two cases have been compared to some (though very few) previously published pertinent values.
