Working with plaster of paris in an experimental flume, the authors have simulated the formation of scallop patterns, an intriguing feature of eroded limestone, under controlled conditions of velocity and viscosity. Analysis of the resulting scallop lengths as a frequency distribution has shown that certain of the statistical parameters are well correlated with the hydrodynamic conditions. Length is inversely related to velocity and directly to viscosity. These results are similar to those found by Curl (1966) in a theoretical dimensional analysis of the simpler flute problem. Work in limestone caverns has confirmed that these results apply to scallops generated on limestone. Certain lithologic effects have been noted, however, and these are believed to be correlated with the physical structure of the material.
