|Title:||Emulation of the Nash-Cascade Model|

|Abstract:||This short Report is concerned with building a bridge between hypothetico-deductive and inductive modeling: between modellers who put their primary trust in their their scientific intuition about the nature of an environmental model and tend to produce quite complex computer simulation models; and those who prefer to rely on the analysis of observational data to identify, in a `top-down' manner (see e.g. Sivapalan and Young, 2005), the simplest form of model that can represent these data. The example treated is concerned with the `Nash Cascade' model used in hydrology (Nash, 1959). This is a connection of n first order, hydrological mass balance elements (or`tanks') connected in series, where each element is described by a mass balance differential equation.|
