Abstract

A critique of the Freeze and Harlan blueprint for a distributed physically based hydrological model leads to the conclusion that it will be abandoned. An alternative blueprint as a modelling methodology is proposed that explicitly recognises the potential for equifinality in scale-dependent model representations. An inductive rather than deductive definition of physically-based is proposed that reflects the important role of observables in constraining the feasible models.
