Influence of seepage change on earth and rockfill dam stability is critical.Seepage monitoring instrument and equipment include osmometer,distributed optical fiber,piezometric tube and measuring weir.In the paper,monitoring instrument and equipment are comprehensively compared and analyzed.The mode of combining traditional monitoring instrument with novel monitoring methods is recommended,which is beneficial for timely analyzing hydraulic gradient in earth and rockfill dam and mastering practical condition of seepage line under the condition of reservoir water level change. It has reference role on developing earth and rockfill dam seepage monitoring and seepage theory research.
