- Six experimentally derived formulae that predict the conditions for alternate bar formation and equilibrium bar dimensions are assessed using field data. The study site is an artificially straightened section of the Embarras River located 16 km

- Century scale patterns of three-dimensional growth and development, and the consequent scaling relations of alluvial bars are examined along the gravel-bed reach of lower Fraser River , British Columbia, Canada. A retrospective view based on maps
- and aerial photographs obtained through the twentieth century shows that individual bars have a life history of about 100 years, except in certain protected positions. Fraser River presents a typical wandering channel planform, exhibiting elements of both
- meandered and low-order braided channels. Hydraulic criteria to which the Fraser bars conform illustrate why this planform develops and persits. The modest rate of bed material transfer along the channel, typical of the wandering type, determines a century
- -length time scale for bar development.

- Ten sites were chosen to be representative of channels in northern Negev, characterized by 3 channel units : bars exhibit steeper than average slopes and poorly sorted mixtures of small-medium cobbles and coarse-very coarse pebbles; flats
- are associated with more gentle slopes and well-sorted medium-fine pebbles and granules; and transitional units have intermediate slopes and grain size. In general, all 3 units are planar, span the full channel width and have well-defined boundaries. Bars
- contrast is the absence of significant bed relief : bars lack crests and flats lack depressions.

- Wave flume experiments on the formation of longshore bars produced by breaking waves

- Mechanisms and processes of longshore bar formation were investigated in connection with vortices induced by breaking waves in the laboratory. Four kinds of wave-flume experiments were conducted using a two-video-camera system to examine
- the vortices and bar formation in detail. Four process models on bar formation are constructed based on the action of vortices: they are models for break-point single bar, inshore single bar, successive multiple bars, and simultaneous multiple bars
- . The occurrence condition for these four types of bars can be quantitatively determined.
- A model of channel response in disturbed alluvial channels
- as an initial site of lower-bank stability. Alternate channel bars form during the restabilization stage and represent incipient meandering of the channel.

- the topographic and textural response of the bed to increased sediment supply. The spatial patterns of bed topography and texture were forced by the flume setup and the initial and final steady states included long stationary alternate bars with associated grain
- size sorting. Bed topography and textural patterns adjusted to increased sediment supply over different timescales. Adjustments in local topography and sorting, primarily in the form of smaller, migrating bars, continued for a period approximately equal

- morphological units (channels, bars, islands) and a range of magnitude of morphological activity from the threshold discharges for gravel transport and minor bar modification up to flows causing major morphological changes. The study was conducted
- of the upper area of a large alluvial fan. The key mechanisms of channel change were avulsions through channel switching into chute channels, meander development through progression and cutoffs, and abandonment of secondary channels. The gravel-bed Danube River
- was characterized by rapide rates of lateral erosion and extensive areas of point bars and gravel bars.

- The central aim of this research is to enhance the understanding of the behaviour of alongshore bars in a water depth of about 2 to 7 m on the time scale of years (medium scale). Such bars are a frequent morphological phenomenon along the Dutch
- coast. To that end, processes on a much smaller time scale were studied; these processes may be responsible for the observed multi-year bar behaviour. The field research was carried out at the central part of the North sea coast at Terschelling
- Controls on formation and form of barred nearshore profiles in Thematic Issue II.
- Linear regression is used to examine effects of maximum fetch length and nearshore slope in controlling characteristics of barred nearshore profiles. Data came from twelve sites in the Great Lakes and two in the Gulf of St. Lawrence. Fetch length
- is a good predictor of height of the outer bar, depth to the crest, and offshore distance| bar number correlates significantly with decreased nearshore slope. Incident waves are the dominant control on nearshore bar formation and maintenance during storms.

- 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
- Stratigraphic architecture and alluvial geoarchaeology of an ephemeral fluvial infilling : Climatic versus anthropogenic factors controlling the Holocene fluvial evolution in southeastern Spain drylands

- Four sets of aerial photographs in the period 1984-2007 were used to map and quantify bar numbers and areas in GIS on an active meandering reach of the River Dane (Cheshire). Bar types were classified. Additional temporal resolution was provided
- by annual ground photography and mapping for 1981-2010. Analysis was extended backward by use of large scale Ordnance Survey maps from 1873 onwards. As expected, point bars are the most common type but free bars of several types are major components of bar
- deposition. Bar activity shows a relation with discharge events and phases and possibly with changing riparian conditions, but superimposed on this is a common sequence of bar evolution from incipient gravel mid-channel bars to full floodplain integration
- . This life-cycle is identified as 7-9 years on average. No evidence for mobility of free bars within the course is found. Variability of bar occurrence needs to be taken into account in river management and ecological evaluation.

- Formation of stationary alternate bars in a steep channel with mixed-size sediment : a flume experiment
- Alternate bars were formed by sediment transport in a flume with Froude-modelled flow and relative roughness characteristic of gravel-boulder channels with steep slopes. This paper describes the experiment and present arguments that steep channel
- gradients and widely graded sediment enhance the stability of alternate bars.
