There are many gullies in loess area, if enough incompact soil accumulates in the gully, it will cause mudflow when encountering heavy rains. Kang gully located in transition of loess tableland and terrace of Weihe River in Weinan, has a larger longitudinal grade, intense erosion of ground water, and abundant source in gully, many mudflows have occurred. Through field investigation and analysis we think: The landform of Kang gully provides spatial condition to formation of mudflow; Planar erosion and gravity erosion for the slope on either side of gully have accumulation effect for material source of mudflow, blocking and burst phenomenon amplify the scale of mudflow, nevertheless, larger mudflow erodes to the slope toe; landslides on either side of gully and mudflow in Kang gully successively occurred under the influence of rainstorm excitation, and they promote each other, thereby forming more destructive landslide-mudflow-barrier lake-landslide, which is primarily a mudflow geohazard chain.
