Outside the university, the citizen scientists play the most important role in the CrowdWater project: They collect and provide hydrological data and help with the data quality control and improvement. The company SPOTTERON is essential for CrowdWater because they are developing and maintaining the app for us and taking care of the legal aspects of collecting such data.
Within the university, two PhD students are responsible for the development of the project and for the scientifical processing of the data. They get support of the two supervising scientists. The community manager checks incoming data, is responsible for the PR work and the support of the citizen scientists.
Credits go to our former PhD students, shaping the project between 2016 and 2020.
I am a PhD student at the University of Zurich and started my work on the CrowdWater project in September 2020. I am from Costa Rica and I have completed my Bachelor’s and Licentiate’s degree in Geography at the University of Costa Rica. My research was about citizen science to generate data about surface water quality, so I hope to continue my research on better methods and approaches to citizen science in hydrology and to apply it in regions like the one I come from.
I am a PhD student at the University of Zurich and I started working on the CrowdWater project in September 2020. I come from Germany and did my Master’s Degree at the Albert-Ludwigs University of Freiburg. With the help of the project I hope to further improve the collection and management of data obtained by crowdsourcing and to awaken the interest of the public regarding water resources and their protection.
I am a visiting PhD student at the University of Zurich and I started working on the CrowdWater project in September 2021. I come from China and I am also a PhD student at Dalian University of Technology. Current research interests include the use of machine learning methods for hydrological monitoring and modelling. For me, it will be exciting to combine the power of citizen science and computers to get more valuable hydrological information.
I am currently doing my Master’s in Physical Geography at the Department of Geography at the University of Zurich. Since December 2019 I am working for the CrowdWater project as a community manager. For me, the combination of hydrology and collaboration with the crowd is very interesting and has a large potential for new findings, which will be valuable here in Switzerland as well as in other parts of the world.
Prof Dr Jan Seibert
As a hydrologist I am curious about water. Current research topics include the use of catchment models for land-use and climate change impact studies, runoff generation processes and their representation in models, the value of different types of data and uncertainty analysis. Today’s mobile devices provide exciting opportunities to include the public in hydrological observations.
Dr Ilja van Meerveld
I am a researcher at the University of Zurich. My research focuses mainly on understanding hydrological processes. I have been involved in field-studies in a range of places (Canada, USA, Alps, Madagascar, Philippines) and am interested in citizen science in hydrology because it provides new opportunities to obtain hydrological data and knowledge, and allows us to study previously unmonitored areas.
Former PhD students
Barbara and Simon joined the CrowdWater project between 2016 and 2020 for their PhD project. When they started in 2016 CrowdWater was just getting started, so they contributed a lot to developing the project, the community and the app. In terms of research both of them focused on the virtual staff gauge, which was a novel approach to crowdsource hydrological data. For detailed information on their research please take a look at their publications.
Dr Simon Etter
The focus of my work was on the value of crowdsourced streamflow and water level class estimates for the calibration of hydrological models. Furthermore, I focused on the quality of water level class data that was collected with the CrowdWater app and with paper forms by citizen scientists as well as the motivations of citizen scientists to contribute.
I will still contribute to CrowdWater and continue to support the project with different contributions.
Dr Barbara Strobl
My dissertation is titled “Quality of Crowdsourced Water Level Observations”. It focusses on the accuracy of water level class data (collected via the virtual staff gauge approach) and on how this accuracy can be further improved. For this we developed the CrowdWater game, which enabled us to crowdsource the quality control and to train new citizen scientists.
My official role in the CrowdWater project might have ended, but I am still an active citizen scientist. I enjoy collecting hydrological data with the CrowdWater app and contributing to the quality control with the CrowdWater game.
