摘要
The debris flows in Cimarong Valley of variable gradients were investigated based on reviewing debris flow studies.The results show that the debris flow there is controlled by slope gradient,with circulation zones and accumulation zones alternating,forming a couple of secondary accumulation areas which results in accumulation in small amounts at the exit.In view of this feature,integrated engineering measures are proposed for debris flow gullies of varying gradients.
