Boundary Stresses and Velocity Profiles in Estuarine Flows: Report 1. InterimCalculation Methods

摘要

Calculation of sediment entrainment and transport rates at open water dredgedmaterial placement sites in tidal waters requires accurate descriptions of velocity profiles and stresses on the sediment bed. Standard equations for calculations in steady, uniform flows can give misleading results when applied in tidal waters. Complicating factors in tidal water environments include tidally reversing flows, density stratification, suspended sediment contributions, and combined current and wind-wave effects. Possible approaches to making calculations in this environment include (a) modified applications of the steady-
