Key science outputs

  • Reservoir chlorophyll concentration
  • Reservoir Cyanobacteria concentration

Introduction

Algal blooms in reservoirs are a potentially serious problem for water quality. Certain types, such as cyanobacteria (“blue-green algae”), have the potential to produce harmful toxins.

Research methods

An algal community model (PROTECH) was applied to simulate the algae of a reservoir under numerous scenarios. The occurrence of blooms and cyanobacteria abundance was quantified.

Results

Predicting the total chlorophyll concentration in reservoir over a range of Thames River flows and reservoir surface water temperatures over the period of June-September (the main growing season).
