The modeling of expert spatial knowledge is obtained by the combining of two different domains: GIS and Expert System. This system, the combining of each domain, enables both expert system and GIS to perform new tasks. An overview of the system in the hydrologic/hydraulic domain is presented. Our object is to provide tools for spatial reasoning in an expert system, for which a prototype is being realized. It will drive the simulation, by choosing differential equations corresponding to a situation in a zone of land, and will ensure the continuity of values of variables near boundaries and the evolving of parameters of equations in zones. Once the parameters are chosen, we can change scenarios (e.g. add a wall or dam, ...) to see the changes in water diffusion. This modeling applied to differential equations of water diffusion in case of natural or artificial rivers enables the risk of flooding to be limited.
