For the support of analysis and decision making in the environmental domain, we propose a knowledge-based system with explicit representation of expertise in the domain and the specific ecosystem in the form of qualitative dynamic models. The choice of qualitative modeling techniques is motivated by the very nature of the processes examined, the available information and style of reasoning employed by human experts. Two other challenges typical for modeling environmental systems are encountered, namely the representation of spatial distribution processes and the interaction of widely different time-scales. We will present the design of the overall system and then illustrate the chosen modeling approach in its application to the phenomenon of algal bloom in a specific river.
