density and channel width) change as (1) vegetation establishes on an initially bareintertidal 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 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
Characteristics and dynamics of multiple intertidal bars, north Lincolnshire, England
Coastal dynamics ; Coastal environment ; Coastal geomorphology ; Digital elevation model ; England ; Interannual variability ; Intertidal zone ; Lincolnshire ; United Kingdom
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
Beach ; Coastal dynamics ; Coastal environment ; Earth surface processes ; Intertidal zone ; Sand bar ; Sediment transport ; Tide ; Wave
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

This paper examines the processes responsible for the morphodynamics of an intertidal swash bar at Skallingen, Denmark, during 7 successive storms. The contributions of gravity waves, infragravity waves and mean currents to the cross-shore suspended
sediment transport are systematically described and related to the morphological response of the intertidal swash bars at Skallingen.
Dynamics of intertidal drainage channels on a multi-barred macrotidal beach

The intertidal drainage channels on a macrotidal bar-trough (ridge-and-runnel) beach, the Leffrinckouke beach in the southern North Sea, were monitored during a 17-day survey. This beach is characterized by 2 intertidal drainage channel types : type
1, dominantly longshore systems essentially limited to the wide intertidal zone; smaller and ephemeral type 2, dominantly cross-shore systems incising bars during spring tides. Channel mobility and impact on beach morphology are expected to increase
Location and height of intertidal bars on macrotidal ridge and runnel beaches
Coastal dynamics ; Coastal environment ; Coastal geomorphology ; Comparative study ; Earth surface processes ; England ; France ; Intertidal zone ; Nord-Pas-de-Calais ; United Kingdom
The principal aim of this paper is to investigate whether the ridges are preferentially located on the intertidal profile where the water level is stationary for the longest time and whether the height of the ridges increases across the intertidal
. It is suggested that the ridges are the result of a combination of swash and surf zone processes acting across the intertidal zone.
Geomorphology of subtidal and intertidal areas in the Southwest of the Netherlands in Developments in physical geography. A tribute to J. I. S. Zonneveld..
In the Southwest of the Netherlands tidal currents are responsible for deposition of subtidal and intertidal sediments in which several characteristic geomorphological units can be distinguished. (AIS).
Intertidal subsidence and collapse features on wave-exposed, drift-aligned sandy beaches subject to Amazon mud : Cayenne, French Guiana

This paper briefly reports on the conditions and processes involved in such deformation features, which reflect active mud burial under sand within the intertidal beach profile.

Digital elevation models and topography profiles of a beach with intertidal bar and through (ridge-and-runnel) morphology in Merlimont, near Somme estuary, were analysed in order to assess patterns of cross-shore and longshore intertidal bar

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
This paper describes an intertidal boulder pavement and associated facies exposed by marine erosion at Cooley Point on the north shore of Dundalk Bay. The boulder pavement is part of a largely submergent facies sequence which is overlain by a late

In this study, an intertidal bar and trough system on the beach of Noordwijk was monitored over a 15-month period in order to examine the daily to seasonal sequential cross-shore behaviour and to establish which conditions force or interrupt
