14. This project has received funding from the European Union’s Horizon 2020 Research and Innovation Action programme under Grant Agreement No 101004157  WQeMS | slide 14 |  www.wqems.eu Water Quality related issues reporting and detection This service allows citizens/water utility operators to report events (e . g . , debris, oil spills, algal blooms) that may affect the water quality in the open surface water reservoirs, through a dedicated mobile application by enabling them to send photos, text and videos about the situation . This information is stored in a repository accessible by the decision maker, who is notified by the system about the occurrence of the event . It also allows decision makers and technical users to be notified about water related issues generated by reports submitted by water utility operators through the dedicated mobile application or through social networks or through CitObs API reports . The registration of an alert can trigger the execution of a related WQeMS service, so that the user can visualize on WQeMS the generated maps and further assess the situation .
