Abstract
    It is argued that a successful ecosystem model can be presented as a deterministic network of processes driven by a mixture of deterministic and stochastic forcing functions, and the structure of such a model of the Bristol Channel and Severn Estuary (GEMBASE) is described. Cruises in the Bristol Channel provided data which were used as initial and boundary conditions in the model and as a verification of the simulation results. Most of the parameter values for the rate equations of the model were derived from the literature, although some were obtained by experimentation; the derivation of parameter values for primary production is described. The simulation results of GEMBASE for 1973 to 1975 are realistic and in good agreement with the field data for that period. Some applications of the models, as a research tool and a management aid, are discussed.
