Tiivistelmä
The purpose of this project was to monitor water quality of river Vantaa during ice and snow melt. Melting of ice and snow increases the rivers discharges for approximately 3 months during spring. Melting waters and increased discharge affect the quality of the river water.
Samples were collected up to 2-3 times during the project. The samples were analyzed in the laboratory of Finnish Environment Institute in Kumpula, Helsinki. Optical measurements were done on sampling day and the rest of the measurements were done at the end of the sampling period.
The results show that the concentration of suspended matter rises when the river discharge increases. The correlation in the results between optical and biochemical measurements was inspected, and it was observed that optical devices can be used to monitor water quality.
