- Processes and rate of retreat of the clay and sandstone sea cliffs of the northern Boulonnais (France)
- Clay ; Cliff ; Coastal environment ; Coastal erosion ; Erosion rate ; France ; Mass movement ; Nord-Pas-de-Calais ; Shore platform
- Retreat of the clay and sandstone cliffs of the northern Boulonnais has been quantified using stereo photogrammetry. The low retreat rate of this coastal strip is far less than that encountered on chalk and clay-chalk cliffs of either side
- of the Channel. The retreat rate is closely related to shore platform morphology and dynamics. This study will help to determine the long term evolution of the Boulonnais coast.

- Retreating cliffs in the humid tropics: an example from Paraiba, northeastern Brazil in Geomorphology of changing coastlines.
- coast, northeast Brazil, under a humid tropical climate, 21 % of the coastline consist of retreating marine cliffs, cut into Plio-Pleistocene sandy clays, a very favourable factor.
- True marine cliffs are extremely rare or almost absent in the humid tropics, where they have been said to be replaced by coastal slopes covered by vegetation, subject to occasional landslides by essentially similar to inland slopes. On the Paraiba
- Factors influencing the rockwall retreat of flysch cliffs on the Slovenian coast
- Adriatic Sea ; Cliff ; Cliff retreat ; Coastal environment ; Erosion ; Flysch ; Folding ; Geomorphology ; Rockfall ; Slope dynamics ; Slovenia
- This study identifies factors that affect the speed of rockwall retreat of flysch cliffs between Kane Point and Strunjan on the Slovenian coast. Individual factors were combined in a geographical information system with mapped recent erosion
- features. The results indicate the influence of individual factors on the formation of erosion rills, gullies, surfwave breaks, slumps, and rockfalls; that is, flysch coast retreat processes. The article also presents the threat due to rockfalls and slumps

- of the intervening interfluves. In this model, retreat of a cliffband occurs when the height of the vertical cliff exceeds a threshold due to incision by channels on the plinth below. Debris derived from cliff retreat is distributed over the model plinth according
- of numerical model experiments : regulating the rate of rockfall to limit the cliff retreat; varying the weathering rate of the rockfall debris.
- to the local topography and distance from the source. This debris then weathers in place, and importantly can act to reduce local bedrock erosion rates, protecting both the plinth and ultimately the cliff from erosion. In this paper, the AA. focus on 2 sets
- The role of groundwater in cliff instability : an example at Cape Blanc-Nez (Pas-de-Calais, France)
- Boulonnais ; Cliff ; Coastal environment ; Erosion ; France ; Groundwater ; Nord-Pas-de-Calais ; Precipitation ; Spatial variation
- The distribution of the amount of retreat in northern Boulonnais is related to structural and topographic factors. Both control the runoff-infiltration balance and therefore the mechanical behavior of the rocks, which determines the modes of failure
- . The spatial variability of the retreat rate is explained, but predicting the temporal variability of the retreat rate, which is central to risk management, is much more difficult.
- Evolution of salt-marsh cliffs in muddy and sandy systems : a qualitative comparison of british west-coast estuaries
- Salt-marsh cliffs in the muddy Severn Estuary are mostly strong and tall. They are retreating in response to the erosive attack of wave and tidal currents chiefly through toppling failures and rotational slips. In the sandy Solway Firth
- and Morecambe Bay systems, marsh cliffs are strong only in their upper parts, where a dense root-mat of marsh grasses binds the sediments. Here cantilever and toppling failures are the main response of the cliffs to tidal and wave erosion. The differences
- between the three estuarine systems in the mechanisms of marsh-cliff erosion are partly reflected in the mode of preservation of the cliffs on the restoration of the conditions leading to renewal of marsh growth.
- Changes in cliffed chalk coastlines are related to variations in the nature of the chalk itself but many cliffs show only minimal retreat of the cliff-top edge because many rock-falls and slides affect lower parts of the cliff-face. Most change
- Rates of slope decline, talus growth and cliff retreat along the Shomyo River in Central Japan : a space-time substitution approach
- Cliff ; Erosion rate ; Fluvial landform ; Fluvial processes ; Honshu ; Japan ; Quaternary ; Slope ; Slope dynamics ; Slope gradient
- On the basis of a space-time substitution, rates of cliff retreat and talus development over the past tens of thousands of years were quantified for valley-side slopes along the Shomyo River with a known rate of waterfall recession. Detailed
- Falls, the growth rate of the talus slope, the rate of decline of the cliff, and the retreat rate of the cliff top are estimated.

- processes of cliffs. Preliminary results indicate that mild winter temperature and direct solar radiation are significant factors controlling cliff retreat rates.
- Lawrence (Quebec, Canada). Specific examples are presented to illustrate the potential of such high-temporal-resolution monitoring systems, not only for quantifying cliff erosion but also for quantifying the influence of thermal regime on the weathering
- Rates and mechanisms of change in hard rock coastal cliffs in Coasts : erosion and sedimentation.
- discontinuity pattern. Emphasis is thus placed on the synthesis of quantifiable rock mechanics parameters and details of change in coastline morphology. Results indicate that although cliff retreat shows no regular spatial or temporal pattern, clear trends can
- Mechanisms associated with the erosion of sand dune cliffs, Magilligan, Northern Ireland
- A fifteen year history of coastal dune recession at Magillan, has revealed both time and space contrasts in processes and morphology. Since 1968 storm frequency has increased, while dune retreat reached a peak in 1978-1979. Three types of dune
- Influence of rock mass strength on the erosion rate of alpine cliffs
- Applied geomorphology ; California ; Cliff ; Erosion rate ; Lithology ; Mountain ; Rock mechanics ; Rockfall ; Sierra Nevada ; United States of America
- The AA. investigate the influence of rock mass strength on the retreat rate of alpine cliffs. To quantify rockwall competence they employed the Slope Mass Rating (SMR) geomechanical strength index. The study area included a portion of the Sierra
- Nevada between Yosemite National Park and Lake Tahoe. The AA. found good correlation between rockwall recession rate determined for 40 alpine cliffs and SMR which is best characterized by an exponential decrease in erosion rate with increasing rock mass
- strength. Analysis of the individual components of the SMR reveals that joint orientation (with respect to the cliff face) is the most important parameter affecting the rockwall erosion rate.
- Land-based marginal ice cliffs : focus on Kilimanjaro
- Cliff ; Glacier ; Glacier retreat ; Ice ; Insolation ; Model ; Mountain ; Photogrammetry ; Radiation ; Tanzania ; Tropical zone
- A review on those ice cliffs, which are mostly associated with dry calving events, is presented. The focus is on the persistent, rarely-calving ice cliffs on the plateau glaciers of Kibo, the main peak of the Kilimanjaro massif, Tanzania. Modelling
- solar irradiance, in conjunction with on-site measurements, revealed that direct insolation is the reason for (1) the predominant zonal alignment of the ice cliffs and (2) their bimodal annual recession. The former peculiarity occurs because near

- Arctic rockwall retreat rates estimated using laboratory-calibrated ERT measurements of talus cones in Longyeardalen, Svalbard
