trapping, the AA. examine the possible role played by intertidal bar and through morphology on longshore and onshore-directed sand transport. Results show that intertidal bars are responsible for significant wave energy dissipation leading to a decrease

Through a review of previously published data across the tropics, average cliff face erosion rates are calculated as intertidal erosion rates and subtidal erosion rates. Intertidal erosion rates are variable within and across latitudinal ranges
. A consideration of temporal variations in intertidal erosion rates provides insights into the potential impacts of climate change on the erosion dynamics of rock coasts in the tropics. This paper highlights some of the interactions over time and space between
A new approach to the problem of measuring microtopographical changes on vertical limestones in the intertidal zone, simple and cost-effective, is discussed. It is based on the positioning of a rock removable slab (RRS) in the intertidal zone

The long-term (10-100 years) evolution of tidal channels is generally considered to interact with bio-geomorphic evolution of the surrounding intertidal platform. Here the AA. studied how the geometric properties of tidal channels (channel drainage
density and channel width) change as (1) vegetation establishes on an initially bare intertidal platform and (2) sediment accretion on the intertidal platform leads to a reduction in the tidal prism (i.e. water volume that during a tidal cycle floods
to and drains back from the intertidal platform). Based on a time series of aerial photographs and digital elevation models, the AA. derived the channel geometric properties at different time steps during the evolution from an initially low-elevated bare tidal

the intertidal sedimentation has followed the rate of relative sea-level rise, at least over the last ∼2000 years, whereas the trends in sediment accumulation rates on the sandy tidal flat in the eastern and exposed part of the lagoon are less clear. The AA

The objectives of this paper are : to examine the geographic distribution of multiple intertidal bars along the coastline of England and Wales to indicate the environmental conditions (geomorphologic setting, waves, tides) that characterize
such morphology; to describe the longshore and cross-shore variability of intertidal bar geometry; and to gain insight into inter- and intra-annual intertidal bar dynamics.

Morphodynamics of intertidal bars in wave-dominated coastal settings - a review

The aims of this review are to identify the dominant morphodynamic processes governing intertidal bar systems and provide a conceptual framework with which these bars can be further investigated. It is the dominant importance of tidal water level
variations and wave processes in shallow water depths (swash and surf zone bores), rather than wave height variability and deeper water wave processes (breaking and shoaling waves), that constitutes the main difference between intertidal and subtidal bar
