We seek to quantify the incipient motion, transport and fate of underwater munitions in coastal environments comprised of mobile beds andor hard bottoms e.g., sandy and gravelrock under a range of relevant hydrodynamic conditions e.g., waves, currents, combined flows. The existing underwater phenomenology of munitions expects mobility to be maximized when munitions are proud i.e., unburied. It has been suggested that the degree of mobility may be orders of magnitude larger when munitions are transported over a hard gravel like substrate where there is little or no sediment cover e.g., such as on coral reefsversus a sandy or muddy bottom. However, there is a dearth of direct observations made under a wide range of controlled hydrodynamics conditions representative of waves and currents. Through an extensive set of detailed large-scale laboratory experiments we plan to develop a complete picture of the phenomena involved in the entrainment, transport, and fate of underwater munitions.
