Estimates of Roughness Coefficients for Selected Natural Stream Channels with Vegetated Banks in New York

Water-surface profiles were recorded and Manning's roughness coefficients computed for a range of discharges at 21 sites on unregulated streams in New York State, excluding Long Island. All sites are at or near U.S. Geological Survey streamflowgaging stations at which stage-to-discharge relations are relatively stable and overbank flow is absent...
