Progress in Management of Sediment Bypassing at Coastal Inlets
elevation is a sensitive factor for reducing wave activity in the inlet entrance channel
and prevent migration of tidal currents through the deposition basin.
Jetty spurs are auxiliary structures that have potential for protecting deposition
basins and reducing sediment movement towards the navigation channel located
seaward of the jetty tips. They also reduce sand bypassing at an inlet by diverting
sediment to locations away from the shadow of the jetty so that reversal of wave
direction will move sediment back to its source region.
This study was conducted as an activity of the Inlet Engineering and the Inlet
Geomorphology and Channels Work Units of the Coastal Inlets Research Program
(CIRP), US Army Corps of Engineers (USACE). Review of this paper by CIRP
colleague Julie Dean Rosati is appreciated. Permission was granted by Headquarters,
USACE, to publish this information.
