Abstract

We provide a mechanistic explanation for observed metrics for drumlins,which represent their sizes and shapes. Our explanation is based on a concept ofdrumlin growth occurring through a process of instability, whereby small amplitudewave forms first grow as ice slides over a bed of deformable sediments, followed bya coarsening process, in which the wavelength as well as the relief of the drumlinscontinues to grow. The observations then provide inferences about the growth processitself.
