Abstract
History is replete with stories recounting the failures of man to recognize, control, and conquer the devastating effects of sediments from steep mountainous lands. Learned men have documented the reasons for the tragic downfall of highly developed civilizations in Mesopotamia, Israel, Egypt, and elsewhere. Most agree that it was not conquest of the land by an invader, nor the loss of fertile fields which depopulated the land, but that the relentless encroachment of silt into the canals and rivers forced the people to move elsewhere or starve.
