Evolution Laws on Longitudinal Slope of Gully Affected by Debris Flow Erosion

Abstract:

Compare to common river bed, the erosion and deposition of debris flow gully have a distinctive phenomenon except big changes of scour depth and deposition thickness. Due to its particularity, the process of gully erosion and deposition, variation of gully longitudinal slope is hardly obtained from field survey and observation. The paper analyzed the research of variation of gully erosion and deposition firstly, then prior to probe the changes of gully surface elevation under debris flow erosion, the variation laws of longitudinal slope of gully with debris flow density, initial angle of gull slope and bed materials through flume experiments.
