Slope Profiles of Cycloidal Form

B. J. BRIDGE 1 and G. G. BECKMAN 1

1 CSIRO Division of Soils, Mill Road, St. Lucia, Queensland, 4067, Australia

Concave profiles of basalt hills in the Darling Downs area of southeastern Queensland can be cycloidal or exponential in form. Where the complete hillslope consists of shallow soils the form is cycloidal. Where colluvial lower slopes are present the overall slope is exponential but the upper, dominantly sedentary portion is cycloidal. The cycloidal form, which corresponds to the curve of least time, appears to be associated with erosional processes and the exponential form with depositional processes.
