Scientific paper

A numerical model has been formulated to simulate the degradational evolution of lunar impact craters, specifically those with a rim-crest diameter range of 1 to 15 km. Meteoritic bombardment is generally considered to be the primary source of erosion on the lunar surface. This repetitive bombardment by small particles and secondary fragments produces individual effects that are small compared to topographic scale and this steady erosional process modifies crater shape as a function of time. The net result of this impact erosion is a smoothing of the lunar surface in a linearly-diffusive manner of degradation.
