Abstract
Debris flow gully has various morphologies because of different type and developed phase of debris flow,and it is important and practical to study the debris flow gully.The valley area,gully length,average bed slope and average valley width of 32 disastrous debris flow gully are analyzed.At last,several conclusions are got,and they will give reference to the assessment of debris flow hazards and prevention to debris flow.
