✦ Synopsis

To retain the advantages of conceptual mdelling while addressing the difficulty of parameter estimtion, a procedure is proposed in which model structure is developed progressively, with model performance and associated parameter uncertainty being evaluated at each stage, to determine whether and which further processes should be added. When developing a structure to model runoff from a large catchmznt, a combination of global statistical performance measures and inforrration concerning conditional error distribution was required; the former to enable the optiml performance of each structural variant to be compared, the latter to assess conformity of the errors to standard statistical assuqtions and hence to indicate how the current variant should be augmented.
