A portable wind tunnel is used to assess the erodibility of prepared surfaces of residue waste. The data are extensive and include wind profiles, collections of saltation and suspension material as well as particle sizing by elutriation. Still, the data show no definitive information on the effects of treatment. The experiments, however, can be characterized by the structure of the measured wind profile; a special plot of the friction velocity and dynamic roughness suggests that only one of the six plots is "all erodible". Surfaces may have a fixed roughness, eroding roughness or exhibit an anomalous "constant friction velocity". There are difficulties in the use of the gradient of the log profile and the intercept as measures of the shear stress and the scale.
