Title: The FBA-Welsh Water simulation model of phytoplankton dynamics in flushed systems. Authentication in a coastal lagoon

Abstract:
This article presents the outcome of attempts to simulate the recorded changes in phytoplankton mass of Slapton Ley during a 12-month period (1970-1971) using the FBA-Welsh Water model evolved to anticipate water-quality problems in the proposed Cardiff Bay Barrage. The direct fit proved to underestimate the main summer crop of Anabaena and Peridinium and was unrealistic in failing to exhaust the dissolved inorganic nitrogen and in depleting phosphorus to the limits of detection. However, adding an internal-load component of suitable magnitude not only simulated the scale and timing of the observed summer maximum but nitrogen fell to limiting levels, while the residual phosphate in the lake water was also of the observed order. Subject only to this modification, the Cardiff Bay model proved to be capable of simulating with considerable accuracy, the actual plankton events in Slapton Ley, nearly two decades beforehand.
