Bibliography ; Coastal environment ; Eustatism ; Global change ; Greenhouse effect ; Impact ; Quaternary ; Sea level ; Shoreline
This report will concentrate on aspects of Quaternary sea-level change, summaries of trends in sea-level over recent decades from tide gauges, and predictions of future sea-level change and the anticipated responses of the coast.

Maree estreme a Venezia (periodo 1872-1981)

Presents new results achieved after analysis of the Venice tide gauge record (San Stefano, Punta della Salute). A continuous series of tide values is presented in tables for the past one hundred and ten years making it possible to distinguish
for the first time astronomical effects from those related to recent human influences. A favourable period, dating from 1970, is now ending. The frequency and severity of flooding will probably increase up through 1987. Thereafter, the situation will slowly

Modelling the effect of waves, weathering and beach development on shore platform development

Modelling the effect of waves, weathering and beach development on shore platform development
Cliff ; Coastal dynamics ; Coastal environment ; Erosion ; Mathematical model ; Model ; Shore platform ; Tide ; Wave
A mathematical model was used to study shore platform development. In addition to mechanical wave erosion, this model considers the effect of a number of other important factors, including platform downwearing by weathering, the abrasive
and protective effects of beach sediment accumulation, and variable cliff height and debris mobility. The primary goal of this study was to examine how these interacting factors influence the development of shore platforms in different environments, rather than

Patterns of surface downwearing on shore platforms in eastern Canada

Canada ; Coastal environment ; Coastal erosion ; Eastern Canada ; Erosion rate ; Experimentation ; Intertidal zone ; Shore platform ; Tide ; Weathering
that tidally generated weathering and debris removal is an effective erosional mechanism, particularly at the elevation of the lowest high tides. Furthermore, even if only one or two mechanisms were dominant in an area, any resulting relationship between
downwearing rates and elevation would be obscured or eliminated by the effect of variations in the chemical and physical characteristics of the rocks.

Stacks and notches at Hopewell Rocks, New Brunswick, Canada

Canada ; Cliff ; Coastal environment ; Coastal erosion ; Coastal geomorphology ; Intertidal zone ; Lithology ; New Brunswick ; Sandstone ; Shore platform ; Tide
Spectacular rock formations have developed in coarse, poorly sorted conglomerates and arkosic sandstones at Hopewell Rocks in the Bay of Fundy, which has the largest tidal range in the world. The purpose of this study was to determine the effect

Tidal wetting and drying on shore platforms : an experimental study of surface expansion and contraction

Basalt ; Canada ; Clay rock ; Coastal environment ; Erosion cycle ; Experimentation ; Intertidal zone ; Quebec ; Shore platform ; Tide ; Weathering
experiments are being concluded to determine the related effects of salts. The greatest amount of expansion and contraction was at the high tidal-level in the argillite and at the mid-tidal level in the basalt, which is consistent with previously measured

Coastal dynamics and impact of coastal protection works on the Spurn Head spit (UK)

Coastal dynamics ; Coastal environment ; Coastal protection ; England ; Estuary ; Geomorphology ; Human impact ; Impact ; Sedimentology ; Spit ; Tide ; United Kingdom ; Wave ; Weather type
the sedimentology and geomorphology of the spit and of the tidal flat behind it (Spurn Bight), and assesses the effects of coastal defences on the nearshore dynamics. The geomorphology and sedimentology of the beaches and the tidal flat were studied to assess

Bedforms and bed material transport pathways in the Changjiang (Yantze) Estuary

This study aims to investigate the bed features in the tide-dominated Changjiang (Yangtze) Estuary using a side-scan sonar and a depth recorder, and to examine the bed material transport pathways on the basis of the maximized gross bedform-normal
to effectively determine the bed material transport directions in the Changjiang Estuary.

Genesis of channel bank overhangs in the Niger Delta and analysis of mechanisms of failure

Bank erosion ; Delta ; Fluvial processes ; Hydrodynamics ; Local climate ; Mathematical model ; Niger ; Nigeria ; Shear stress ; Soil moisture ; Stratigraphy ; Tide ; Vegetation
The instability of channel banks carries a significant economic implication because of its effect on navigation and channel commercial development. Field observation and analysis indicate that factors such as stratigraphy, local climate, bio

Tidal wetting and drying on shore platforms : an experimental assessment

Canada ; Coastal environment ; Experimentation ; Intertidal zone ; Ontario ; Quebec ; Shore platform ; Tide ; Weathering
This paper reports on a laboratory investigation to determine the effect of alternate wetting and drying and debris removal in the intertidal zone of rocky coasts. Many of the cores experienced very little to no breakdown, particularly those from

Etude de l'effet de marée océanique sur un aquifère carbonaté côtier (Miocène de l'Algarve-Portugal)

The study of groundwater tables variations due to ocean-tide effects in a coastal aquifer may yield its hydrodynamical characteristics. Such a study has been attempted about a zone of the limestone of the Miocene of Algarve (Portugal). Two

Measurement and modeling of moisture content above an oscillating water table : implications for beach surface moisture dynamics

Beach ; Coastal environment ; Experimentation ; Hysteresis ; Model ; Simulation ; Soil moisture ; Tide ; Underground water
This study examined the influence of tidally-induced oscillations of the beach water table in regulating beach surface moisture dynamics. Laboratory experiments were conducted to assess the influence of hysteresis and transient flow effects

Boulder deposition during major tsunami events

A remarkable accumulation of marine boulders located above the present spring tide level has occurred in 2 coastal lowlands of the Algarve (Portugal). The spreads of boulders extend several hundred meters inland and well beyond the present landward
the observational data on boulder dimensions (density, size, distribution) on the most likely processes of sediment deposition. This work demonstrates the effectiveness of the study of boulder deposits in tsunami reconstruction.

Erosion and accretion processes in a muddy dissipative coast, the Chao Phraya River delta, Thailand

Seasonal variation in seabed elevation in the muddy intertidal zone of the Chao Phraya River delta was assessed using information on waves and tides predicted by numerical simulations. Observations, aimed at evaluating the effectiveness

Topographical effects on the equilibrium-line altitude on glaciers

Topographical effects on the equilibrium-line altitude on glaciers
The most useful parameter to quantify the climatic effects on a glacier is the equilibrium-line altitude (ELA) : a line on the glacier where accumulation equals ablation. In this paper, the topographical and morphological effects on the ELA
