Abstract: A numerical approach is considered for flow over side weirs as a substantial part of distribution channels in irrigation systems and treatment units. The model is based on the energy principle and a curve-fitting technique. ...

Abstract: A theoretical analysis based on the energy principle for discharge over side weirs was presented, and its application was demonstrated using a numerical approach. The decrease in water surface elevation in lateral direction ...

Abstract: The performance characteristics of a granular media trickling filter were modeled using a dispersed flow hydraulic model and Monod-type biological kinetics assuming a uniform biofilm thickness. Numerical methods and computer ...

Abstract: A relationship between the removal efficiency and hydraulic regimes of granular‐media trickling niters is presented. Using an equation derived in a previous paper to determine dispersion numbers, effluent concentration is ...

Abstract: An assemblage of spheres having a rhombic arrangement, whose spacing among the particle centers is adjusted according to the specified porosity, is used as a model to investigate the physics of the unsaturated flow through ...

Abstract: An equation previously derived is experimentally verified and its practical application is considered. The results are compared with the methods previously proposed in the literature. The application of this theory to the ...

Abstract: The application of a mathematical model developed by the writer to fluidization of filter media is presented. An assemblage of spheres having a rhombic arrangement with spacing between particle centers adjusted according ...

Abstract: Theoretical and experimental investigations of the flow over sharpedged side weirs in circular channels are reported. A theoretical model can be obtained from energy principles, and it is solved by a finite difference ...

Abstract: The average water surface slope in the lateral direction is taken into account as a local parameter ψ to study flow over a side weir. It was later shown that for smaller side weir lengths and side weir portions with no ...
