Résumé
Les conditions particulières prévalant lors de l’application d’une approche de gestion par bassin versant au Québec (Canada) font appel à de nouvelles méthodologies intégrées pour faciliter l’analyse et le partage des informations, les conditions de négociation entre les parties prenantes et la mise en oeuvre des choix d’aménagement ou de gestion retenus. Cet article met en perspective la modélisation des processus décisionnels territoriaux à l’échelle des bassins versants (BV). Il dégage certains enjeux méthodologiques se rattachant à cette problématique de gestion dans sa dimension informationnelle, dans le contexte du Québec. Il montre l’interconnexion des préoccupations décisionnelles aux conditions d’utilisation d’une plate-forme géomatique à même de modéliser de tels processus territoriaux dans le cadre d’un système intégré d’aide à la décision (SIAD). Finalement, il recommande l’évaluation de l’utilisation d’un tel système (SIAD-BV) pour faciliter l’émergence des conditions d’application de l’approche de la gestion intégrée par bassin versant au Québec, à partir des discussions réalisées avec des intervenants des bassins Chaudière et Outaouais.

Abstract
The unique conditions that prevail when a political approach to watershed management in Quebec (Canada) is taken, requires a need for integrated methodologies to promote the following: information sharing and analysis, negotiation of conditions among stakeholders and introduction of selected management alternatives. This article brings the modelling of regional decision-making processes that apply to watershed management (WM) into perspective. It discusses the methodological challenges relating to information that are inherent to this management issue, particularly in a Québec (Canada) context. It shows links between decisional concerns and geomatic skills for modelling these regional processes, as an integrated decision support system (IDSS). Lastly, it recommends assessing the use of this type of system to promote the emergence of conditions where such an approach to watershed management in Québec could be implemented, based on interviews conducted with regional professionals in the Chaudière and Outaouais basins.
Key Words:
- watershed management,
- modelling spatial decision process,
- integrated decision support system (IDSS)
