Vegetation is an important factor of a drainage basin, especially the river channel. Since 1967, although considerable interest has been created in fluvial geomorphological aspects of drainage basins, the significance of vegetation has not been considered in an integrated way. It appears from the recently published accounts of channel forms and processes that there is now a general agreement over the significance of vegetation in the management of a river channel. The precise way in which this factor affects the river behaviour is however, still not very clear.

The study focuses on the influence of a variety of channel variables on the bed vegetation in down- stream direction and across the channel. The associations and correlations between these factors and the bed vegetation do reveal the complexity of environ- mental interactions.

The methodology adopted was based on specific lithological, hydrological and vegetational aspects of the river channel. The primary focus of this work is to ascertain the linkages between geomorphological, hydrological and ecological processes and the bed vegetation which are a part of Phyto geomorphology and ecology of the river basin.
