and developmental stages. The management implications of the model and associated observations of the role of riparianvegetation in island development are considered.
Against a background of a strong alpine to mediterranean climatic and hydrological gradient, this paper explores relationships between topography, sediment and vegetation at 8 sites along the active zone of the Tagliamento. A conceptual model
of island development is proposed which integrates the interactions between large woody debris and vegetation, geomorphic features, sediment calibre and hydrological regime. Depositional and erosional processes result in different island types

The aim of this research is to assess quantitatively the temporal changes in channel morphology and flood power in an unregulated bedrock canyon, and relate them to woody vegetation change. The study area is the lower canyon of Harris Wash

The AA. quantified how rates of stream channel migration in a montane meadow vary as a function of the riparianvegetation community. The South Fork of the Kern River at Monache Meadow, located in California's southern Sierra Nevada range, supports
2 distinct types of vegetation : a dry and a wet meadow community. The AA. measured rates of lateral stream migration for dry versus wet meadow reaches from aerial photographs spanning a 40-year period (1955-1995). They used a linear model of meander
The distribution of riparianvegetation in relation to channel morphology is poorly understood in canyon rivers, which are characterized by in-channel fluvial sediment deposits rather than flood plains. This study focuses on vegetation and sandbar
characteristics in 2 reaches of the lower Little Colorado River canyon in Arizona : one reach with ephemeral flow from the watershed, and another with perennial baseflow from a spring. Both reaches have been colonized by the exotic Tamarix chinensis, a riparian

the AA. show that there are more or less predictable patterns of stream power and rates of vegetation growth, reflecting water availability during dry periods and also the availability of sand and finer sediment. The AA. relate these to the pattern
of island distribution that is repeated within the 3 reaches and is indicative of the engineering role of riparian trees.

The AA. measured the effect of wet meadow vegetation on the bank strength and failure mechanics of a meandering montane meadow stream, the South Fork of the Kern River at Monache Meadow, in California's Sierra Nevada. Streambanks colonized by wet
graminoid meadows vegetation were on average 5 times stronger than those colonized by dry xeric meadow and scrub vegetation. The measurements show that strength is correlated with vegetation density indicators, including stem counts.

This paper jointly analyses multitemporal, multispectral ASTER data, continuous river stage and discharge data, and field observations of the growth rates of the dominant riparian tree species (Populus nigra) along a 21 km reach of the Tagliamento
River, Italy. The study period (2004-2009) of increasing flow disturbance allows the exploration of vegetation dynamics within the river's active corridor under changing flow conditions. The analysis demonstrates the utility of ASTER data
The ecohydrological state of a stream is determined by a set of hydromorphological, hydrobiological conditions of water, by the character of bank and riparian belts and transformation of the floodplain. The method of ecomorphological evaluation

Relations among vegetation, processes, and landforms are described here for representative streams of four areas of the United-States: high-gradient streams of the humid east, coastal-plain streams, Great Plains streams, and stream channels

Analysis of the contemporary geomorphology, vegetation and in-channel wood within the relatively pristine Thurra River in southeastern Australia provides insight into river behaviour prior to European disturbance. Sedimentological evidence is used
erosion rates, and in-channel deposition are substantially influenced by vegetation and wood within the channel and on the floodplain.

Based on field and archival evidence from Seward and Morton Counties, Kansas, the AA. find that channel narrowing, which began in the 1940s, continues to the present. The channel changes and increase in riparianvegetation both appear to have been
caused by a decrease in annual peak flows, which favored in-channel sedimentation and the expansion of riparianvegetation. The decrease in annual peak flows coincided with a reduction in the annual variation in moisture conditions, as measured

The AA. discuss the role of Large Woody Debris, LWD, in the development of montane riparian forests and present a conceptual model of this biogeomorphic process. Riparian forests are shown to be significant in the development of channel morphology
The potential of a high resolution multi-spectral airborne remote sensing to detect and quantify changes in channel morphology and riparian land cover are illustrated. The River Tay is a partially embanked wandering gravel bed river, and Airborne

An integrated geomorphological and ecological approach was adopted to investigate the relation between recent channel adjustments and riparianvegetation evolution by performing a large-scale multi-temporal analysis of channel and land cover
by substantial changes in the riparianvegetation. Major differences may be noted between the studied river reaches in relation to their state of naturalness, floristic richness and differentiation in vegetation types, which appear particularly controlled
