Description 831-840
This paper consists the
effects of bed parameters changes on rip current pattern and sediment transport
in channels by means of numerical simulations. Model predictions are compared
with field observations showing a reasonable agreement. Results of this
research show the general pattern of hydrodynamic current in the form of eddies
with reverse vorticity along the sides of rip current, so that the rate of
erosion along the rip channel and location of sedimentation towards the
offshore zone are affected by these eddies. Present study shows that
morphologic changes in rip channel have a direct relation with non-dimensional
rip flow velocity () and changes in bed parameters, in a way that changes in
non-dimensional cross-sectional flow area () are severely affected by
the distance of bar from the shoreline and slope.
