Journal Article
Journal: GSA Bulletin
Published: 01 August 1978
GSA Bulletin (1978) 89 (8): 1133–1139.
...ROGER N. DUBOIS Abstract The development of beach cusps was studied along the northern shore of Delaware from June 9 through June 30, and from July 28 through August 10 of 1976. At the study site, the formation of beach cusps was dependent upon the existence of a tidal berm in the developing stage...

...ROGER N. DUBOIS Abstract The development and maintenance of beach cusps were studied along a shore segment of the Delaware coast from June 5 through June 28, 1979. On three occasions, a berm and a series of beach cusps developed together on the foreshore as part of rebuilding processes following...

...ROBERT A. DALRYMPLE; GLENN A. LANAN Abstract From the time when theories were first postulated on beach cusps, intersecting wave trains have been mentioned as one possible mechanism for cusp formation. However, this mechanism has been largely ignored, and no real effort has been made to understand...

...PAUL D. KOMAR Abstract Beach cusps, uniformly spaced mounds or ridges of sediments that trend at right angles to the shoreline, are observed at Mono Lake, California. The cusps have spacings ranging from 11 to 59 cm, making them some of the smallest examples of natural beach cusps that have been...

...RICHARD J RUSSELL; WILLIAM G McINTIRE Abstract Beach cusps develop along seaward faces of growing berms. They appear early in the transitional period of decreasing wave energy from winter- to summer-beach conditions. Growth stages are described and related to currents within the swash zone. Cusp...

...Andre Guilcher Abstract On the basis of observations along the coasts of western Brittany (France) and southwestern England, concludes that beach cusps are more widely developed in sand than in pebble deposits and that the interference of two different wave systems, rather than the presence...

...DOUGLAS WILSON JOHNSON Abstract “Selecting any pebbly beach where the stones are prevailingly of small enough size to be readily tossed about by the waves, the observer will note that at almost all times, but especially after a heavy storm, the slope from the high-water mark downward is scalloped...

...Henry S. Chafetz; Gary Kocurek Abstract Coarsening-upward sediment accumulations comprise horns of beach cusps on the upper foreshore of Big Shell Beach, central Padre Island, south Texas coast. The thicknesses of the coarsening-upward grain size sequences are about equal to the relative relief...

...Ervin G. Otvos Abstract Conditions necessary for the formation and preservation of sandy and pebbly beach cusps and pebble ridges perpendicular to the shoreline are determined at Westbrook, Conn. They consist of adequate source material, sufficient breaker energy, a balance between swash energy...

...Olivier Monfort; Franck Levoy; Claude Larsonneur Abstract Beach cusps are sometimes present on the upper foreshore of sandy beaches along the northwest coast of France characterised by very large tidal ranges. These forms were observed on the high tidal zone of Luc-sur-Mer in the "baie de Seine...

... of laboratory wave basin experiments is presented in which the cell circulation of water modifies an initially smooth and straight sand beach. In all cases, it is found that cusps develop in the lee of the rip currents so that a series of cusps is formed with the same spacing as the rip currents...

... of the fine beach sediments has been derived locally. Among the ephemeral beach phenomena are some which appear to be analogous to large ripple marks or beach cusps, and which seem to be controlled by local conditions of slope and angle of wind and waves.

... but this is an exaggeration of sinuous water motion or hydraulic drag already present in the straight stream. A physical model demonstrating the initiation of meandering is also described which apparently is, in essence, similar to the initiating mechanism responsible for production of beach cusps and other evenly spaced...

...N. C. Flemming Abstract Nine experiments with 2-inch waves breaking for 24 to 48 hours on a beach of pebbles and sand produced cusps in eight cases. Seven runs produced continuously changing cusps; the last run, after two hours, produced cusps which remained stable for 24 hours. The stable beach...
