Sedimente in Gewässern enthalten eine Vielzahl chemischer Verbindungen, unter anderem Nährstoffe, Sauerstoff und toxische Schwermetalle wie Cadmium. In diesem Band werden mathematische Methoden zur quantitativen Vorhersage des Flusses solcher Chemikalien vorgestellt. Als Eingangsparameter sind nur die Menge der betreffenden Verbindung und die Zustandsgrößen des umgebenden Wassers erforderlich. Die Algorithmen eignen sich hervorragend zur Einbindung in moderne Modelle der Wasserqualität. (04/00)

Summary
Presents mathematical models for estimating and predicting sediment fluxes. These models provide sufficient detail and data to enable scientists in the field to reproduce the computations and use the models for understanding their own data. This title offers computations directly applicable to developing modern water quality models.
