Abstract:

LONG-TERM GOALS. Development of an accurate, real-time, mine burial prediction capability by field testing and validation of an integrated, physics-based, mine burial model. OBJECTIVES. Sediment-structure interactions are responsible for the burialpenetration of heavy objects, such as bottom mines, pipelines, concrete breakwaters, and offshore platforms in the seafloor. On seabeds of low shear strength mud, these objects are known to penetrate on impact when the bearing capacity of the seafloor is exceeded, with additional subsequent burial from sediment consolidation and creep. On sand seabeds, burial is common by scour and fill, momentary or cyclic wave-induced liquefaction, and seabed morphological changes e.g., transverse bedform migration, changes in shore-rise and bar-berm conditions, sediment deposition. Using a field experimental approach, the Naval Research Laboratory NRL will test and evaluate physics-based mine burial processes and models in order to provide the US Navy with an accurate, real-time mine burial prediction capability.
