Abstract Managing siltation in reservoirs behind earthen dams remains a central challenge for ensuring long-term water storage, structural safety, and optimal dam function. The advent of automatic silt ejector systems—engineered to continuously or periodically remove sediment without labor-intensive intervention—offers an innovative approach to sediment management and dam sustainability. This review synthesizes the state of technology for automatic silt ejectors, focusing on their principles, integration with modern monitoring platforms, design considerations, and operational challenges. Emphasis is placed on technological gaps, especially regarding automation in small to medium earthfill dams, and the need for robust monitoring to ensure system effectiveness and dam safety. --- 1. Introduction Earthen dams (synonymously, earth-fill or embankment dams) are widely used in global water management for irrigation, municipal supply, hydropower, and flood mitigation.
