At the same time, a user-friendly web interface has been developed so users can view in a few clicks the forecasts for their selected water bodies.<\/p><p>During the summer of 2025, initial beta-testing began with partners in Canada and Europe. These extensive trials mark a key milestone: they allow to assess the relevance of different features, to test the system performance in real-world conditions, and to gather user feedback. The insight from these trials plays an important role in enhancing the user experience and polishing predictive models. They also reflect growing interest from stakeholders, who are discovering a tool capable of transforming the way they approach water body management.<\/p><h3>Become a Groundbreaker!<\/h3><p>Subscribe
