2. Summary

This research is carried to predict the Chl-a concentration in the water system to investigate the relationship between Chl-a and algal bloom, so the final objective is to find the adequate Chl-a criterion which able to be used to predict algal bloom. The results of the EFDC model are compared with the criterion, then prediction accuracy was graded.

 

EFDC model can predict the Chl-a concentration well, except for some areas. When the criterion is configured to 30ug/l, the prediction accuracy is about 63%. So, we can assume that there has a relationship between Chl-a and algal bloom.

 

To improve the EFDC model, 1) some discussions for the input variables are needed, 2) algal production rate should be modified because it is a very complex variable, and 3) it is needed to set the adequate criterion to predict algal bloom following the water system, respectively.

 

3. Originality and Creativity

- The criterion on Chl-a is used to determine the algal bloom using the results of the predicted Chl-a concentration.
