Abstract

A model for the prediction of concentration profiles in a weired river system R. de Groot Riwa, Netherlands Abstract During the past decades several models which predict the concentration profiles after a discharge of pollutants in a river have been developed. Application of these models to a river with weirs leads to discrepancies between predicted and measured concentration profiles. A model that compensates for these discrepancies has been developed and is presented here. The lead of the concentration maximum in the time domain was used to calibrate the model. The model was calibrated using chloride measurements and verified with ample independent real life data. The differences between the model described in this paper and the Rhine Alarm Model (RAM) are discussed. Application of the model to a weired river showed significant improvement compared with existing models. 1 Introduction 1.1 Geographical and hydrological situation The waterworks N.V.WRK, (Nieuwegein, the Netherlands) extracts
