摘要：

Modelling of water and solute movement in soils generally requires a great number of parameters which are imprecise. In this paper, we focus on various types of imprecisions introduced either by subjective or state-of-the-art estimates of coefficients, or through measurement error, and on their evaluation by fuzzy set and fuzzy logic theory. After summarising the theoretical framework, the paper provides an example of an application dealing with estimates of imprecisions associated with the advective flux of atrazine in the unsaturated calcareous soil of the Grand Morin watershed, France.
