The hygienic quality of the water of the Kerava river, southern Finland, deteriorates occasionally.
The purpose of the study was to design a real-time monitoring system that would inform the public using the river for recreational purposes about the changes in water quality.
The system was constrained to consist of on-line sensing of water quality and quantity, and adjacent forecasting models.
Four different system alternatives were analyzed and compared.
The first alternative observes river flow in real-time; the second alternative also monitors water temperature, turbidity, pH, conductivity and dissolved oxygen.
The data collected in this way are used to forecast Streptococcus and E. coli concentrations, using canonical correlation and regression analysis.
