Dams are massive structures, crucial for water resource management. These structures undergo deformation over time. To keep these structures safe, continuous monitoring is essential. In this study, several years of satellite-based observations are used for deformation monitoring in six dams situated in California, tracking how they deform on a seasonal scale. We combined this satellite data with information about rainfall patterns and reservoir water levels. Findings show that all the dams we studied move in predictable seasonal patterns that closely follow the rising and falling patterns of the reservoir water level during the rainy and dry seasons. Our findings contribute to a better understanding of the seasonal deformation behaviors of dams under different seasonal conditions. This knowledge will help dam operating agencies to better understand normal seasonal behavior and potential risks when abnormal deformation. Climate change brings more extreme weather patterns, making it harder to predict how dams will respond, making this study more critical for dam safety and health monitoring of the dams.
