Robots, drones and thermal cameras are measuring Vantaanjoki
Freshwater Competence Centre
Finnish partnership for freshwater research
Spring is here and so is the field work season. Finnish Environment Institute and Aalto university started the measuring campaign last week at Vantaanjoki and now that the snow is disappearing, it is soon time for the laser scanning sensors of FGI and the robot boat of University of Turku to do their measurements in the same area.
Field work is almost never boring - there was some excitement this time as well, with one of the measuring boats taking off on its own. The current in Vantaanjoki is strong at this time of the year. Happy news is that the escaped research equipment was recovered and the measuring devices were unharmed.
We had a journalist from the local newspaper Vantaan Sanomat following us in the field and interviewing our scientists on the location, explaining what this campaign was all about. Here a short summary:
Researcher Joonas Kahiluoto from Finnish Environment Institute tells, that the measurements at Pitk?koski of Vantaanjoki river have been carried out for a long time, but this time several measuring methods are focused on one location. Underwater measurements are also a new thing at Vantaanjoki - there is a camera under the ice.

–?New measurement technologies teach us more about the river. With these measurements we can understand the connectivity in the catchment area better. Decision makers can see what type of actions are needed and where, Development manager Anna-Kaisa Ronkanen from Finnish Environment Institute explains.
For example floods in the inhabited areas can be better predicted, when accurate models with real-time updates exist, tells Research professor Harri Kaartinen from Finnish Geospatial Research Institute FGI.
Another measurement focus is the discharge volume and velocity, that have an impact on for example how much nutrients the rivers are able to carry into the Baltic Sea. There has been changes in the discharge of Vantaanjoki due to the changes in the Finnish winters.

7 个月You are doing interisting work. Periodic detailed analysis of the river water in different locations and dates will be a mine of data mainly if compared to results of last years. Deep analysis of the collected data base may provide details related to the impact of human activities, climate change, etc. This analysis may be extended to the interface zone with the sea. Hope that results will be published soon and compared to that of other rivers and serve as guidelines for other teams.
