摘要

Dams and reservoirs are key for UN Sustainable Development Goals, especially SDG 6 (clean water) and SDG 7 (affordable clean energy), and also support SDG 2 (zero hunger) and SDG 13 (climate action). Early dams provided irrigation, flood protection and water supply; today over 62 000 dams operate worldwide, one-sixth generate electricity. Their safe, resilient and sustainable operation faces tectonic, geological, climatic, hydraulic load, sedimentation, concrete ageing and maintenance challenges. The BMBF-funded DAMAST projects have implemented monitoring at the 271 m Enguri Dam in Georgia, which supplies 100 % of Abkhazia's and around 40 % of Georgia's electrical power demand. Seismicity, annual variation of water level up to 100 m, high sediment load and its 1970s design make it an ideal test case for induced seismicity, sediment dynamics and regional deformation. Monitoring combines GNSS, PS-InSAR, ground-based SAR, seismic networks and AI-driven data fusion to capture millimeter-scale movements, seismic clusters and modelling of sedimentation processes, providing a comprehensive basis for risk assessment, damage detection and predictive modelling.
