| 英文摘要 | Deposition is often the only relic left by a debris flow and therefore the only source for estimation of hazards. Fortunately, real debris flows consisting of surge series have been observed every year in Jiangjia Gully, Yunnan, China, providing a complete scenario of debris-flow deposition. Observations of surges suggest a relationship between the initiation and deposition in sense that the stopped surge is in the semblance of flowing surge, which allows one to infer the deposition from the motion. Deposition thickness is assumed to take distribution similar to the flow depth, both in form of power law. And through the Weibull distribution of flow velocity, a lower limit can be settled for the power exponent of the thickness distribution, which turns out to be further related to the hydrograph of debris flow. Findings in this paper provide a quantitative way for evaluating debris flow. |
