Marie-Odile Cordier SACADEAU: A Decision-Aid System to improve Stream-Water Quality , Ercim news , Vol. 61 , 37--38 , april , 2005 Abstract The objective of the SACADEAU project is to build a decision-aid tool to help specialists in charge of catchment area management to preserve stream-water quality. This is done by coupling a qualitative transfer model (simulating pesticide transfer through the catchment area) with a qualitative management model (simulating farmers� decisions concerning weeding strategies and herbicide application). This has two main advantages: it allows the impact of recommendations to be evaluated by simulating high-level scenarios, and it allows simulation results to be analysed by using machine learning and data mining techniques to discover discriminating variables and to acquire knowledge in this poorly understood domain. The experimentation site (the Fremeur catchment area) is located in Brittany, France and covers about seventeen square kilometres. This web site is maintained by René Quiniou using the Weave system from the Caravel project: http://www-caravel.inria.fr. Last modification: 10-07-2011 09:54:25
