WebThe n values are a composite of information compiled by Engman (1986). Includes species such as weeping lovegrass, bluegrass, buffalo grass, blue grama grass, and native grass mixtures. When selecting n, consider cover to a height of about 0.1 ft. This is the only part of the plant cover that obstructs sheet flow. Parent topic: CN Weighting. WebM is the inverse of Manning's n roughness coefficient (i.e. 1 n ). The values of Manning's M and their equivalent n values used in the model are given in Table 1. ... View in full-text
