Abstract Qualitative reasoning methods have proven useful to extract qualitative information from quantitative data in a wide variety of applications. In this work, we analysed a 30 months record of runoff and sediment yield from an experimental station in Benidorm, SE Spain, comprising a total of 104 rainfall events. We adopted a decision-tree approach to identify the environmental variables, basically rainfall characteristics, which were the most informative to predict the production of runoff or sediment and, for thes
