Roughness coefficients for high-gradient channels in New York State
Manning's roughness coefficients (n values) were computed for a range of flows at six streams in New York State (USA) that have high energy gradients (greater than 0.002) and large median bed-particle sizes (between 0.14 and 0.36 meters). The coefficients, which ranged from 0.034 to 0.061 for bankfull flows, were computed from discharges, channel geometry, and water-surface profiles measured at ea

Design of Manning's-roughness-coefficient study in New York State
Field-collected hydraulic data can be used to compute roughness coefficients for channels with different hydraulic characteristics. Suggested criteria for the design of a roughness-coefficient study include: (1) location of the study reach close to an established streamflow-monitoring site with a stable high-flow stage-to-discharge relation; (2) uniform hydraulic conditions within, and upstream an

Evaluation of wet-line depth-correction methods for cable-suspended current meters
Wet-line depth corrections for cable-suspended current meter and weight not perpendicular to the water surface have been evaluated using cable-suspended weights towed by a boat in still water. A fathometer was used to track a Columbus sounding weight and to record its actual depth for several apparent depths, weight sizes, and towed velocities. Cable strumming, tension, and weight veer are noted.
