Paper Title
Early-Alert System of Reservoir Failures Using Ground Water Level

Abstract
Climate change and facility aging lead to the reduction of reservoir safety that may bring reservoir failure, which results in the loss of lives and property damage in downstream areas. Therefore, it is necessary for downstream residents to provide an Early-Alert System for Reservoir (Dam) Failure to detect early signs of failure (with sensors) in real-time and perform safety management to prevent or minimize possible damage. Ground water level meters were installed to monitor changes of seepage line for understanding stability of dam body, and the management criteria were established. 15 analyzed data results showed that the values are scattered. It means that each reservoir has its own geotechnical characteristics, very different from others, so it is necessary to establish individual management criteria of ground water level based on 1 year test monitoring to set up for numerical fitting.
