Abstract: Sediment‐driven density currents exist in most secondary sedimentation basins and cause the usual hydrodynamic flow pattern in these basins to deviate substantially from uniformity. The mathematical model introduced here ...

Abstract: A mathematical model of sediment laden, density affected turbulent flows is presented. The finite element technique is used in conjunction with the Newton iterative method to solve the resulting partial differential ...

Abstract: A skimming well is a partially penetrating well in a thin unconfined layer of fresh water which overlies saline water in an aquifer. A three‐dimensional, unconfined, transient miscible flow model of skimming well operation, ...

Abstract: The equation governing the concentration field for a dilute suspension of particles is presented for flow in circular and rectangular primary settling basins. The formulation is valid for two‐dimensional, mean steady, ...

Abstract: A Froude number that is applicable to subdivisions of a cross section is developed assuming one-dimensional flow. The subdivision Froude number is shown to determine accurately the flow regime in subdivisions of a cross ...

Abstract: In the steady flow computation of water surface profiles with one-dimensional models, bridges across floodplains require special attention. Accurate prediction of energy losses in the reaches upstream and downstream of the ...
