  • Alongshore variation in beach cusp morphology in a coastal embayment
  • Australia ; Beach cusp ; Coastal dynamics ; Coastal environment ; Model ; New South Wales ; Wave
  • The variation in beach cusp characteristics was examined along a 1 km long embayed beach (Pearl Beach, New South Wales, Australia), to test the edge wave model and the self-organization mechanism of beach cusp formation.
  • Variations of spacings between beach cusps discussed in relation to edge wave theory
  • Beach cusps ; Coastal dynamics ; Coastal environment ; Denmark ; Model ; Statistics ; Wave
  • Variations in cusp spacings of beach cusp systems have been examined, and the conclusion is that the apparent regularity of the spacings is not always real. Established edge wave theory predicts equal cusp spacings, and accordingly, the theory needs

  • This paper provides a detailed description of the development of a natural beach cusp system in Perth, Western Australia. Observations of the incident wave conditions, instantaneous shoreline and three-dimensional beach morphology were obtained over
  • a period of 6 days. The results obtained provide a clear insight into the morphodynamics of natural beach cusps.

  • This study assesses the impacts of morphologic variations, associated with beach cusps and nourishment material, on volume change estimates from profiles and shoreline change at 0.5 to 3.5 year time periods. Volume changes at the edges
  • of nourishment areas are not captured well by profiles. When the nourishment material is graded to a ramped morphology, which minimizes across-beach morphologic variability, the shoreline-change proxy does accurately estimate volume changes. Both proxies estimate
  • volume changes inaccurately at beaches where volume changes oscillate between erosion and accretion on both short and long time scales because the magnitude of small-scale changes in volume from the formation and erosion of morphologic features
  • , such as cusps and berms, will always be similar to the longer-term net volume change. This study suggests that decadal records of shoreline change, which are commonly developed using aerial photography, can be used to help identify the best proxy for estimating
  • volume change; however, recent anthropogenic modifications that impact patterns of beach sedimentation, including nourishment, terminal groins, and inlet-channel dredging, makes decadal records less useful.

  • The dynamic of urbanization can be produced by the transition from a low level stable equilibrium to a high level stable equilibrium corresponding to a cusp catastrophe. An economic theory yielding this type of dynamic is discussed, formalized

  • At the northern coast of the Sambian Peninsula longshore sediment drift proceeds in the form of short (up to 3-4 km) oppositely directed flows; zones of their divergence are located at the coastal protrusions (cusps), while the convergence takes
