Planning and Design of a Low-Weir Section Jetty (Coastal Engineering Conference in Santa Barbara, California, October 1965)
A berm and dune project for shore and hurricane protection was recently completed at Wrightsville Beach, North Carolina. A navigation project provides for a 14-ft-deep navigation channel...

Bed Forms Due to a Fluid Stream
A general investigation of the occurrence of bed forms is reported. A relationship is determined for finding the point at which ripples would replace the flat bed. From the Bagnold number,...

Mechanism of Sand Movement on Coastal Dunes
Sand supplied to a coast by streams, cliff erosion, and other sources generally is moved in one direction along the shoreline as littoral drift under the action of the prevailing wave...

Stabilization of Sand Dunes at Vandenberg Air Force Base
A serious problem was posed by sand movement and deposition affecting the operation of coastal training facilities at Vandenberg Air Force Base. Progressive wind erosion required immediate...

Study of Sediment Ripple Formation
Laboratory results are used to show the variation of the bed friction factor with the formation of ripples and dunes under flowing water. The flow pattern in the lee of a ripple is compared...

Resistance to Flow in Alluvial Channels
Paper presents initial results of flume study of alluvial channels; detailed classification of regimes of flow, forms of bed roughness, and basic concepts pertaining to resistance to flow;...

Resistance to Flow in Alluvial Channels
Paper presents initial results of flume study of alluvial channels; detailed classification of regimes of flow, forms of bed roughness, and basic concepts pertaining to resistance to flow;...

Ground Water Flow in the Netherlands Coastal Dunes
A mathematical analysis of the ground water conditions in that portion of the Netherlands coastal dunes which furnish a water supply to Amsterdam is presented. The problem is treated two-dimensionally...

Mechanics of Sediment-Ripple Formation
Literature reviewed; ripples are caused primarily by instability of zone of high velocity gradient at surface of sediment laden bottom; for practical application experimental criterion...
