Abstract	:	"This is an account of the mechanics, prediction and countermeasures of debris flow, from both a theoretical and applied standpoint. The qualitative and fundamental character of this book makes it a valuable textbook for graduate level courses, but it is also recommended reading for those with a professional interest in the mechanics and counter-measures of debris flow in engineering, geosciences and water resources."--Jacket.
