Samenvatting

There is an urgency for developing methods that are capable of monitoring water systems that are fast changing due to climate change and increase of anthropogenic pressure. Updated and real-time detailed data is necessary to support water and soil management strategies. This study evaluates the implementations of novel techniques in different socio-economic settings. Sensors and cameras were installed in mobile platforms (including boats and underwater drones), and deployed to assess spatial data variability. Environmental scans were performed at multiple locations with different water systems in The Netherlands, Indonesia and Denmark. Results from the multiple methods (sensor, cameras) provided new insights into spatial variation of water quality, contrasting with traditional point sampling. Feedback from water authorities and other stakeholders indicate that collected data can be used to support management actions, and that such increasingly accessible technologies contribute to creating awareness to water related issues.
