This paper describes and explains channel metamorphosis of the Ain River in east-central France and the effects of this metamorphosis on floodplain disturbance and vegetation development: relationship between channel dynamics and hydrology
Vegetation is the most important intermediate through which climate and land use modify geomorphological processes and landforms. In this paper the AA. explore three types of model which attempt to simulate the links to uncultivated vegetation, all
sharing a common basis in hydrology. In all cases, the model leads to a unique stable vegetation cover, irrespective of the initial conditions, but it is recognised that there may be better model parameterisations.

This paper quantifies the distribution of soil nutrients, natural and anthropogenic disturbances, and vegetation structure at the scale of patches that exist within a landscape of relatively uniform aspect, elevation, climate, and bedrock geology.

This paper presents the results of a study of relations between woody vegetation and channel morphogenesis in gravel-bed streams of the Ozark Plateaus. These results have implications for general models of channel morphogenesis in gravel-bed streams

Using semivariance statistics, the AA. analyze the spatial relationship between the hydrogeomorphology and the pattern of vegetation cover of the Amazon River floodplain in Brazil during high water. Classified Landsat images for three reaches
of the river that represent the geomorphology of thhe channel-floodplain system were analysed to show the upstream to downstream variation in the spatial heterogeneity of the floodplain environments. In addition to hydrogeomorphic inluence, vegetation

This paper presents the results of the subproject to map portions of the riverbed which may be sensitive to vegetation expansion if flows are reduced in the future. One flow reduction scenario was developed and examined by combining field
measurements of riparian vegetation gradients and river cross-sections, digital elevation modeling, and a geographic information system.

This paper reports on hydrogeomorphological research undertaken within a drainage basin, in the New Forest, which contains two types of semi-natural vegetation cover which are a diminishing resource within the UK: lowland heath and floodplain forest
. This research investigates interactions between vegetation and hydrogeomorphological processes, but also focuses more specfically on developing a fuller understanding of the hydrogeomorphological functioning of drainage basins under these two diminishing cover
