Impact craters in sand
Witryna2.1 Impact Crater Shapes: Simple Craters The shapes of simple craters are calculated from R=KrV 1/3 D=depth=KdV1/3 The values indicated by the data and programmed are: The rim diameter is assumed to be 1.3 times the excavation diameter and the lip height 0.36 times the rim diameter, consistent with the data and measured lunar simple craters. http://isjos.org/JoP/vol1/Papers/JoPv1i1-1Craters.pdf
