International Symposium
Third Circular

The significance of soil surface characteristics in soil erosion

20–22 September 2001, University Louis Pasteur, Strasbourg, France

Organized by RIDES group (National Research Programmes for Hydrology – PNRH and for Soil Erosion – PNSE), network of several research groups of CNRS, INRA, IRD and Universities. Supported by PNRH, BRGM, ESSC, INRA, UNESCO, Université Louis Pasteur
Symposium Objectives and Scope

The aim of the meeting is to provide a forum for the presentation and discussion of recent developments in understanding the influence of soil surface characteristics (SSC) on infiltration and on the hydraulics and spatial organization of runoff and sediment transport in the catchment system. This symposium follows on the first Assessment of Soil Surface Sealing and Crusting (Ghent, Belgium, 1985), the second Crusting symposium (Georgia, USA, 1991) followed by the third Sealing, Crusting and Hardsetting Soils (Brisbane, Australia, 1994). It is anticipated that issues of spatial and temporal scaling of processes and parameter measurements will be addressed at the meeting.

The meeting will develop along major themes exploring the SSC control on: hydrodynamic properties, organization of the micro and macro-porosity at the soil surface, dynamics of SSC in relation to interactions between climate, land use, biological activity, depression storage, overland flow and related parameters at spatial scales from less than 1 m² up to small catchments (<1 km²). In the framework of the COST 623 Working Groups activities, a follow-up meeting addressing SSC-related issues of spatio-temporal organization and connectivity of runoff at the plot to catchment scale is planned in 2002 in Muencheberg, Germany.

1. Elementary processes and thresholds in soil surface dynamics

2. The effects of soil surface characteristics on wind and water erosion

3. Surface characterisation at point to catchment scales

4. Drivers and management of soil surface characteristics


Oral Presentations

The time interval for oral presentations is 15 minutes including discussion. Slide projector, overhead projector and video projector will be provided.

Poster Presentations

The Poster size should be 100 cm by 140 cm (width by height) max. Poster sessions will be introduced by short (1 minute) oral presentations. The objective of the one-minute presentations is to help other researchers to decide which posters are of greatest interest to them.

Each person has a maximum of 1 minute to present an outline of his/her poster. In this short time, it is better to explain a few things clearly than many things badly. We suggest that you focus on maximum three or four key points during your talk. Only one single overhead transparency may be shown. Do not try to squeeze too much onto this transparency! Note that it may be in colour. Note also that, if you wish to convey more detailed information regarding your poster, you could prepare some handouts to be distributed during the poster sessions.


All abstracts accepted for presentation during the symposium will be published in a book of abstracts that will be made available to all participants at the outset of the symposium. An updated copy of your abstract can be send before 31 July 2001 by e-mail to

Publication of papers

It is intended to publish papers of the symposium in a special issue of International Journals (Earth Surface Processes and Landforms, Hydrological Processes). The deadline for receipt of your paper is 15 October 15 2001. The contribution should not exceed 6000 words, including tables and figures.
