*Brink depth characteristics include the relationship between brink depth (y*

_{o}) and critical depth for parallel flow (y_{c});...Onset of Instability of Power-Law Fluid in Couette Flow

*The critical Reynolds numbers at the onset of instability of a Newtonian and a power-law fluid, respectively, in the annulus between two coaxial cylinders, with the inner cylinder rotating...*

Effect of Channel Shape on Gradually Varied Flow Profiles

*An analysis of gradually varied flow profiles with Froude number as a reference parameter is made. Generalized nondimensional varied flow profiles of the M and S types are computed for...*

Efficiency of Hydraulic Jump

*It has been shown that the existing definitions of the efficiency of hydraulic jump do not furnish a correct picture of the physical phenomenon. A more rational definition of the efficiency...*

Hydrodynamic Effects of Seepage on Bed Particles

*The effect of effluent and influent seepage on the hydrodynamic forces acting on an idealized noncohesive sediment particle are investigated experimentally. The hydrodynamic conditions...*

Fluid Force Analysis and Accelerating Sphere Tests

*An adequate expression for the fluid force on an accelerating body depends on whether the history of motion is repetitive. The conventional form for periodic motion consists of the sum...*

Drag Coefficients in Nonsteady Turbulent Flow

*Drag coefficients for spheres in nonsteady turbulent flow are found to be functions of the acceleration number, and either the particle Reynolds number or the relative turbulence intensity...*

Junction Losses in Laminar and Transitional Flows

*Analytical and experimental studies were carried out to develop additional data on energy losses at a junction for systems operating in the Reynolds number range of between 10 and 10,000....*

Experiments on Plane Couette Flow

*A simple method for generating plane Couette flow is described. In this technique the water surface of a covered open-channel flume represents the moving boundary, and measurements are...*

Fluid-Dynamic Consideration of Bottom Materials

*Bottom materials often involve clay-water suspensions which evidence complex rheology. Studies of the non-Newtonian behavior of kaolin are reported herein. Concentric viscometer analysis...*

Characteristics of Flow over Weirs of Finite Crest Width

*The characteristics of flow over weirs of rectangular cross-section with finite crest width depend on h/P, h/B, a characteristic Reynolds number, K/h, and Weber number, wherein h, P, B,...*

Dispersion in Natural Streams

*The one-dimensional mathematical model of dispersion has been developed to account for the loss of dye due to decay and adsorption. This model predicts the time-concentration of the conservative...*

Anemometer Height in Froude Scaling of Wind Stress

*Extending previously proposed Froude scaling of wind stress coefficients, the paper suggests the appropriate anemometer heights for different wind fetches, and proposes a procedure of...*

Unified Analysis of Grid Turbulence

*The deficiencies of the conventional power laws for the decay of grid turbulence, i.e., the discontinuous change from an initial to a final zone and the undefined range of validity, have...*

Modelling Tidal Flow from Harbors

*Problems concerned with the tidal flow of water into and out of harbors are difficult to solve mathematically. For the case of flow in a channel the Froude number may be considered to...*
