Analysis of gradually and spatially varied flow in sand-bed channels
Journal of Hydraulic Research/De Recherches Hydrauliques, 2010 Seepage through a sand bed affects the channel hydrodynamics, which in turn alters channel stability. Thus, the effect of seepage on its hydrodynamic parameters needs to be ascertained.

Velocity Distributions in Spatially Varied Flow with Increasing Discharge
Journal of Hydraulic Engineering, 2007 The experimental study presented in this paper explores the distribution of the mean velocities for a channel receiving spatially varied (SV) inflow from directly above the centerline of the channel via sets of nozzles.

Modeling Orthokinetic Coagulation in Spatially Varying Laminar Flow
Journal of Colloid and Interface Science, 2000An orthokinetic coagulation model including the effects of agglomeration and local stress-induced aggregate breakup was developed. This model was used to simulate coagulation in the flow between two eccentrically located and rotating cylinders. Four methods of modeling coagulation in the flow system were examined.

Spatially Varied Flow over Side-Weirs
Journal of the Hydraulics Division, 1972An experimental investigation of the flow over sharp edged side-weirs in rectangular channels is reported. The experiments cover subcritical and supercritical flow regimes with weirs of zero as well as finite height. The subcritical flow experimental data agree well with the derived analytical expression for the variation of the De Marchi coefficient ...

Resistance Coefficients for Steady Spatially Varied Flow
Journal of the Hydraulics Division, 1972In spatially varied flow three coefficients in Weisbach f form are involved which are sometimes termed resistance coefficients. They are the frictional resistance coefficient, the dissipated energy coefficient, and the total head-loss coefficient. In general these three coefficients are not equal whether there is lateral flow or not.

Spatially varied flow equations
Water Resources Research, 1969The momentum and energy principles are equally applicable in the derivation of spatially varied flow equations. By applying the energy principle and introducing a slope of energy head Se, the resulting spatially varied flow equation takes a different form of several terms containing the slope and the effect of added or extracted discharge from the ...

Dynamic Equations for Steady Spatially Varied Flow
Journal of the Hydraulics Division, 1970Dynamic equations for steady spatially varied flow in uniform channels are derived separately based on momentum and energy principles. It is shown that the momentum equation is inherently different from the energy equation. In general, six different gradients are involved in steady spatially varied flow: the friction slope in the momentum equation, the

Hydraulics of Spatially Varied Pipe Flow
Journal of the Hydraulics Division, 1967The flow profile in a gridiron drainage main tile where lateral inflows enter at constant intervals is studied in detail. Theoretical equations are derived for computing flow profiles. Experimental observations are made to check the theoretical computation.
