The strain distribution is in the presented model dependent on the representative grain size $d$.
However, it is uncomfortable to describe the grain size distribution with a single value for diamictons such as most subglacial tills \citep[e.g.][]{Hooke1995}.
Future research will investigate how wide grain-size distributions affect strain distribution.

+We expect that a volumetrically dominant grain size dominates the strain distribution, outside of effects of ploughing by large clasts \citep[e.g.][]{Tulaczyk1999}.
