Webn = Manning’s roughness coefficient for open channel flow. Manning’s n values for open channel flow can be obtained from standard textbooks such as Chow (1959) or Linsley et al. (1982). After average velocity is computed using equation 3-4, T t for the channel seg-ment can be estimated using equation 3-1. Reservoirs or lakes WebUSGS
