Abstract: The Hazen–Williams formula is frequently used for the design of large-diameter pipes, without regard for its limited range of applicability. This practice can have very detrimental effects on pipe design, and could potentially ...

Abstract: The prediction of bridge-pier scour has been mostly aimed for a single pier of various sizes, shapes, and alignments with flow. For the case of multiple piers, widely used manuals still recommend using single-pier scour ...

Abstract: The unsteady three-dimensional (3D), nonaerated, skimming flow over a stepped spillway is investigated by means of a detached eddy simulation (DES). Special emphasis is placed on the description of the instantaneous velocity ...

Abstract: Recent empirical and numerical evidence shows that the Basset force plays an important role in the description of acceleration of relatively small sediment particles moving close to solid boundaries. This force can make ...

Abstract: Temperature index snowmelt models often require representation of a snowpack’s melt rate. Defining the melt rate as a function of an accumulated number of warming degree-days is achieved in some temperature index models ...

Abstract: The estimation of flow-induced shear stresses acting on the surface of scour holes still represents a challenge for scientists and engineers. From the practical point of view, excessive shear stresses can lead to significant ...
