Fuzzy committees of specialized rainfall-runoff models: further enhancements and tests

Often a single hydrological model cannot capture the details of a complex rainfall-runoff relationship, and a possibility here is building specialized models to be responsible for a particular aspect of this relationship and combining them to form a committee model. This study extends earlier work of using fuzzy committees to combine hydrological models calibrated for different hydrological regimes - by considering the suitability of the different weighting function for objective functions and different class of membership functions used to combine the specialized models and compare them with the single optimal models.
