✦ Synopsis

Many models have been used to characterize dispersion of fluids in flowing systems. Some account for both transverse and longitudinal dispersion, while others account for longitudinal dispersion alone. Inaddition, thevariety of experimental tracer methods used to find the parameters of the models makes the resultant analyses seemingly unrelated.

We show here the relationship between these models and generalize all the previously presented measurement techniques.

This gives a comprehensive picture of the field of dispersion, allows a quantitative evaluation of the error incurred when a simple model is used in place of a more exact but more unwieldy model, and gives future experimenters the necessary information to decide what combination of experimental set-up and mathematical model yields, within prescribed limits of error, an analysis of desired accuracy.

Part I of this paper discussed methods for experimentally finding dispersion coefficients for each of the two important classes of dispersion models. We treated the models as if they were completely separate. Now these models are interrelated and are also related to the more general models which do

The generalization of the parameters of rainfall-runoff models, to enable application at ungauged sites, is an important and ongoing area of research. This paper compares the performance of three alternative methods of generalization, for two parameter-sparse conceptual models (PDM and TATE), specif
