An Approach For Integrating Fuzzy Rule System
In Hydrological Modeling

Abstract
When uncertainty is important, the fuzzy set theory offers a framework for
processing qualitative information. In such a model, variables are treated as fuzzy
numbers and calculations are replaced by inference rules. Therefore, we built
some tools in order to introduce qualitative knowledge in the field of hydrology.
Firstly, a C library has been developed, including basic fuzzy tools.
Secondly, we built a fuzzy rule model software in which several algorithms
are taken into account : defuzzification, aggregation rule, logical operator
definition. The case-study concerns the determination of the ten year runoff
coefficient in the Sahel area for which an evaluation method is based on three
variables : the area and the slope of the basin, and an infiltrability index. In the
