ABSTRACT
Hydraulic filling remains arguably a relatively new geotechnical engineering process, despite having been used for decades to construct mega projects around the globe. The publication of the Hydraulic Fill Manual has been an important initiative to standardize some key aspects of the hydraulic filling process. However, there are key aspects such as consideration of contractual arrangements that are aligned with current industry trends, characterization of the ‘at source’ and ‘after deposition’ properties of the hydraulic fill, and performance criteria of the fill mass for which further/revised guidance may be needed. This paper reviews the current state of hydraulic filling guidance documents and offers some suggestions for future developments.
