Book Description
Validity of seven analytical formula as well as linear and non-linear multiple regressive schemes was tested using field data from the Outer Banks, North Carolina. Generally, agreement proved unsatisfactory. Field experiences indicate that the longshore current is a velocity field consisting of a multitude of velocity vectors whose basic pattern varies depending upon the regimes of wave-current-topography interaction. The need to recognize topography as a responding variable as well as a process variable in the physical scheme of longshore current is emphasized.

Book Description
The report presents a theoretical analysis on the generation and stabilization of nearshore, wave-induced circulation and longshore current patterns produced by the interaction of the incoming waves and local bottom topography. This interaction results in a spacial variation of wave characteristics which produces the driving mechanism for nearshore circulation patterns. Both normal and oblique wave incidence are considered with the imposed beach profiles developed from an examination of prototype data. The analytical model results are compared to field measurements and yield optimistic results. (Author).

Book Description
Rhythmic patterns of topography may be apparent simultaneously in a longshore alternation of cuspate projections and arcuate embayments along the beach face, in a rhythmic longshore bar composed of an alternate series of arcs and cusps, and in longshore undulation of the nearshore bed. Development and modification of rhythmic topography were monitored for 3 weeks along the Gulf Coast at Seagrove Beach, Florida. The indication is that, independent of scale, rhythmically spaced cuspate projections along the beach face can be either modified arcuate deposits or cuspate forms resulting from the formation of arcuate embayments by erosion.

Book Description
This book provides a thorough treatment of both theoretical and observational aspects of the interaction between the sea-floor and the near-sea-floor dynamics; the effect this has on the distribution of internal and seabed stress; and the relevance of the associated dynamics to sedimentation processes. The theoretical work described involved both analytical and numerical modelling studies of a wide range of near-shore and shelf processes. These provide a valuable store of information on the interaction between the sea-floor and the dynamics of the overlying water. The book also includes an account of tidal analysis techniques and how these are being applied in the analysis of tidal current measurements. The observational studies relate to measurements of near-sea-floor turbulence and sand-transport in the littoral zone.
