The GroundwaterDrought project aims to develop and introduce an innovative analysis and information system throughout Switzerland that enables users to precisely analyse and interpret groundwater dynamics, extreme events and anthropogenic influences. Based on time series from water suppliers and supplementary cantonal and national data, the aim is to create a powerful tool for analysing and interpreting measurement time series that visualises changes in groundwater systems over space and time. The system will help water suppliers to identify periods of drought, extremely low water levels and long-term trends in groundwater availability, as well as periods of increased water supply due to higher winter precipitation. In addition, the tool serves as an indicator of anthropogenic influences, such as changes in pumping regimes, construction activities or agricultural water withdrawals, and thus contributes to the early detection of changes in groundwater dynamics. At the heart of the project is the development of an interactive, web-based analysis tool that can be easily integrated into the existing work processes of water suppliers. It enables comprehensive evaluations, comparative analyses and the visualisation of trends and anomalies. This provides water suppliers with a uniform and practical basis for long-term monitoring, evaluation and strategic planning.
