✦ Synopsis
A method that combines calibration and identi®ability analysis of a dynamic water quality model to evaluate the relative importance of various processes aecting the dynamic aspects of water composition is illustrated by a study of the response of suspended sediment and dissolved nutrients to a ¯ood hydrograph in a rural catchment area in the Netherlands. Since the water quality model simulates the observed concentrations of suspended sediment and dissolved nutrients reasonably well, the most important processes during the observed ¯ood hydrograph could be determined. These were erosion, exchange between dissolved phase and bed sediments and denitri®cation. It is concluded that the method is very useful for identifying the most signi®cant model parameters and processes that are essential for water quality modelling.
