摘要：It was Determined the current persistence components were significant in hydraulic designs of highland zone with sharp slopes. It was defined to examine the consequence of gradient, rapidity, depth and dimension of coarseness on the manning coarseness factor in this superficial river area. This is an investigational education about manning coarseness defined for highland zones protected by elements in three diverse dimensions and three slopes for dissimilar hydraulic situations in a flume of 8.3 m long, 0.8 m width and 0.5 m height under bed gradient of 0.0005. The current variations in contradiction of the Manning coarseness quantity were exposed, which comprises above hydraulic components considered. The herbal management, water balance are significant component drainage slope experimental. It was determined soil superficial roughness and hydraulic roughness factor are significant hydraulic resistance feature components. Exactly approximating the hydraulic roughness factor is significant to considerate instruments of drainage slope.
