Bedrock channels are defined here loosely as river channels that are incised primarily within a solid geology. Although there may be a variable fill of loose sediment within the channel, the river morphology is not largely a response to scour and fill of the alluvial fill. Interest in bedrock channels seems to be growing apace. For example, they are being used as indicators of tectonic history. Similarly there is a burgeoning interest in the hydraulics, geomorphology and biotic characteristics of these channels. The purpose of this group is to provide a broad forum within which people of widely differing interests can make new contacts, exchange ideas, discuss issues and obtain information. The objective is to provide a service that will lead to better international exchange of information such that scientific understanding of the dynamics of bedrock channels is promoted.

As part of this initiative a web based discussion forum has been established at the address below. Any interested party can log-on within this site, which is intended to promote discussion of relevant issues, advertise forthcoming meetings and provide access to materials such as images for research and teaching.



The IAG/AIG Working Group on Hydrology and geomorphology of bedrock rivers is organising a special session on a special session on ‘Hazards and hazard management in bedrock channels’ at the IAG/AIG Regional Conference in Mexico, 27 October – 2 November 2003. The general theme of the Conference is “Geomorphic Hazards: Towards the prevention of disasters”. Within this purview little is know about bedrock channels. Consequently papers and posters presented in the proposed special session may broadly address processes and responses in bedrock channels understanding of which, in time, will aid hazard management. Various processes in mountain and other bedrock channels pose a hazard to life and property. Papers on flood hydraulic processes, CFD modelling, impacts on natural vegetation, other ecological issues, management and remedial actions are welcome as are papers and posters on channel morphology, tectonics and case studies etc.If you intend to present a paper or a poster in this session could you please contact Prof. Paul A. Carling (Department of Geography, University of Southampton, Southampton, UK. e-mail: This is to prepare a list of possible participants who should be kept informed regarding future developments.

PLEASE NOTE THIS SESSION DOES NOT APPEAR IN THE FIRST CIRCULAR but details will be added to subsequent announcements.
