Comparison of shear stress calculations has been made between the conventional profile method and the method proposed by Ling and Untersteiner (1974) by using the corrected drag plate measurements of the Kansas Field Program of 1968 made by the Air Force Cambridge Research Laboratories. A von Karman constant of 0.35 has been used for this comparison. The proposed method gives better stress estimates and less scatter in the roughness parameter than the conventional method.
