Flow Resistance Induced by Overland Flow Morphology
1992In this paper an effort is made to develop a new physically-based overland flow model which accounts for raindrop mixing and for the complex overland flow geometry. Theoretical curves relating overland flow parameters are found and compared to field data.

Diameter variability and microvascular flow resistance
American Journal of Physiology-Heart and Circulatory Physiology, 1997Microvessels are known to exhibit irregular shapes, deviating substantially from an idealized cylindrical tube geometry. Such irregularities must be taken into account in calculating microvascular flow resistance and may add to the observation that flow resistance in living microvessels in vivo is about twice that predicted on the basis of tube flow ...

Gene flow from glyphosate‐resistant crops
Pest Management Science, 2008AbstractGene flow from transgenic glyphosate‐resistant crops can result in the adventitious presence of the transgene, which may negatively impact markets. Gene flow can also produce glyphosate‐resistant plants that may interfere with weed management systems.

Journal of Hydraulic Engineering, 2002
In 1965, Rouse critically reviewed hydraulic resistance in open channels on the basis of fluid mechanics. He pointed out the effects of cross-sectional shape, boundary nonuniformity, and flow unsteadiness, in addition to viscosity and wall roughness that are commonly considered.

Journal of Hydraulic Engineering, 1991
Flow-resistance coefficients are essential in determining both water-surface elevations and velocities that are used in many aspects of channel design. Channel boundaries requiring scour protection are often armored with riprap revetments that have roughness characteristics that differ from other channel boundaries.

Simplified Flow Resistance Measurements
The Journal of the Acoustical Society of America, 1946A simplified apparatus for the measurement of the flow resistance of porous acoustical materials is described. The method used is absolute, not comparative. An improved technique for the preparation of the samples is discussed.
