ABSTRACT

Extensive research has been carried out in the field of scour around bridge piers in past, which resulted in development of various mathematical expressions for computation of equilibrium scour depth. The modern trend in scour investigations is to study the temporal variation of scour rather than the equilibrium scour because the equilibrium scour occurs after a very long period of time. In this paper method of Kothyari et al. (1992) for computation of temporal variation of scour around circular pier has been modified with aid of experimental data of present study and data of various investigators. The mathematical model presented herein has potential of application for computation of temporal variation of scour depth around prototype circular bridge during the passage of the flood hydrograph.
