Finally, the thesis analyzes statistical laws of the maximum saltating height and saltating length of saltating sand grains and they follow Gamma function distribution. This is consistent with the results of water-sand motion. It shows that statistical laws of saltating height and saltating length of saltating sand grains are independent of the medium of flow. It is possible the nature of saltating sand grains.
