Cover Story: Shore-based video monitoring has been proved to be a valuable tool for coastal studies. As waves have visible signatures on the sea surface in the nearshore, coastal images can be used to characterize the wave types. This work presents a technique to determine the wave transformation domains with images taken by coastal video monitoring stations. Shoaling, surf and swash zone boundaries are automatically identified exploiting the change in pixel intensity. The applications of the technique are numerous and cover hydrodynamic analysis, morphological studies and coastal images processing. View this paper.

Geomorphology of a Holocene Hurricane Deposit Eroded from Rhyolite Sea Cliffs on Ensenada Almeja (Baja California Sur, Mexico)

  • Markes E. Johnson,
  • Rigoberto Guardado-France,
  • Erlend M. Johnson and
  • Jorge Ledesma-Vázquez

This work advances research on the role of hurricanes in degrading the rocky coastline within Mexico’s Gulf of California, most commonly formed by widespread igneous rocks. Under evaluation is a distinct coastal boulder bed (CBB) derived from b...

Effects of Wave Orbital Velocity Parameterization on Nearshore Sediment Transport and Decadal Morphodynamics

  • Marcio Boechat Albernaz,
  • Gerben Ruessink,
  • H. R. A. (Bert) Jagers and
  • Maarten G. Kleinhans

Nearshore morphological modelling is challenging due to complex feedback between hydrodynamics, sediment transport and morphology bridging scales from seconds to years. Such modelling is, however, needed to assess long-term effects of changing climat...

Performance Analysis of Conical Permanent Magnet Couplings for Underwater Propulsion

  • Yukai Li,
  • Yuli Hu,
  • Baowei Song,
  • Zhaoyong Mao and
  • Wenlong Tian

Permanent magnet couplings (PMCs) are widely used in underwater propulsion because it can solve the deep-sea sealing problem effectively. In this paper, a new type of conical permanent magnet coupling (CPMC) is proposed, which is able to match the ta...
