| Abstract: | The prediction of the dangerous extent of a debris flow deposition is of vital importance, but difficult to achieve. Precise
prediction of the depositional boundary of a debris flow event is impossible, but the size of a debris flow deposition could
provide some estimates of the area, length, width, and thickness of a debris flow deposition. Based on in situ depositional
experiments performed on a debris flow creek just after debris flows, a rule of thumb expressed by a group of equations containing
the multiple-variate nonlinear functions is proposed in this paper. The interrelationships between the size and the causation
also are discussed, and some empirical formulae to calculate the causative parameters for different regions are presented.
