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...

Estimation of load exceedances of an aircraft undercarriage with nonlinear properties excitated by random runway unevenness

In this report various methods to describe a landing gear with nonlinear properties and excitated by random runway unevenness during taxying have been investigated. The results of calculations have been compared to measured results from an analog computer simulation. The mean behaviour, standard deviations and power spectra, can be described...

Wave attenuation in a channel with roughened sides

A semi-empirical study l~as made of the attenuation of water waves in a rectangular channel, the side walls of which had been provided with regularly spaced roughness strips. Such strips were found to be highly effective wave dampers. A dimensionless resistance coefficient could be deduced from the attenuation data; this coefficient was mainly a...

The use of artificial roughness in movable-bed models

Tests have been done in a laboratory flume, to evaluate the influence of vertical rods of 3 mm dia on the hydraulic and sedimentological characteristics of the flow. The first two tests have been done with some 10 cm waterdepth. In both tests the s ame flow rate and sediment transport was used, the only difference between the tests being the...
