The recession of a coast can destabilize coastal cliffs. The stability of a cliff is controlled by a rock bridge. Identifying the volume-expansion point of rock bridges is crucial to assess cliff stability, but currently there are few identifying methods.

Geomorphological control on boulder transport and coastal erosion before, during and after an extreme extra-tropical cyclone [PDF]
Extreme wave events in coastal zones are principal drivers of geomorphic change. Evidence of boulder entrainment and erosional impact during storms is increasing.

Erosion and sediment supply of sea cliffs of Todos Santos Bay, Baja California, from 1970 to 1991
Aerial photographs from INEGI for October 1970, October 1985, July 1989 and September 1991 were analyzed to calculate the cliff retreat rate and sediment volume supplied to the coastal system in four coastal sectors of Todos Santos Bay: San Miguel, El ...

A geotechnical and GIS based method for evaluating risk exposition along coastal cliff environments: a case study of the chalk cliffs of southern England [PDF]
The present work has established a methodology that allows the user to determine areas susceptible to shoreline recession and cliff instability. This methodology includes the development of a qualitative loss estimation system which utilizes geotechnical

ASSESSMENT OF THE PRECISION OF A SMART-PHONE POLE PHOTOGRAMMETRY FOR A SECOND-ORDER CLIFF SURFACE DEFORMATION STUDIES [PDF]
Coastal cliff is almost a vertical elongated structure with a wave-cut notch and a landslip. Cliffs are geological formations with an almost unpredictable and unstoppable detachment between constitutes formations.

Modelling of wave climate and sediment transport patterns at a tideless embayed beach, Pirita Beach, Estonia [PDF]
Nearshore sand transport patterns along the tideless, embayed Pirita beach, Tallinn, Estonia, have been investigated utilizing high-resolution modelling of wave processes combined with bathymetric surveys and sediment textural analyses of the nearshore ...

Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Beach and cliff retreat induced by storm groups at Forte Novo,Algarve (Portugal) [PDF]
Littoral cell dynamics may change through time as a reaction to modifications of the coastal system. Along the Vilamoura-Quarteira coastline, the construction of a groin field limited the sediment supply to the already narrow Forte Novo beach, located ...
