Abstract: A computer model was developed simulating flow and aeration requirements for a range of farm sizes, from 50 to 2000 hectares. Climatic effects and water quality upset conditions were included in the model as well as routine flow and aeration requirements. Several sensitivity runs were executed to determine the effect of the individual variables on the requirements. The results indicated that for farm sizes exceeding 200 hectares, water requirements drop dramatically from 50 liters/s to less than 15 liters/second/hectare, while aeration requirements dropped from 8 to 6 HP/hectare. For a 1000 hectare farm the seawater flow requirements drop from 50 to 15 cms, which represents a major saving in capital costs.
