Predicting the Mobility and Burial of Underwater Unexploded Ordnance (UXO) Using the UXO Mobility Model (ESTCP) 200417

摘要

The ESTCP Unexploded Ordnance (UXO) Mobility Model (MM) validation program expanded the capabilities of the vortex lattice based model previously developed by the Navy for mine modeling applications and then validated the MM with surrogate ordnance in two instrumented field demonstration, one in each of the most common coastal environmental types (Trailing Edge and Biogenic Reef):U.S. Army Filed Research Facility (FRF), Duck, NC, and pacific Missile Range Facility (PMRF), Kauai, HI. The MM correctly predicted all the basic behaviors of the surrogates; the skill factor for modeling migration and burial exceeded 0.8 in both cases, a favorable result with respect to modeling coastal processes and mine burial prediction. The MM is calibrated for the most common coastal environmental and can use wither default environmental conditions or site-specific data inputs to more accurately predict overall probability of movement. It is noted that the primary cost drivers for varying levels of analysis is predicated on the amount of site data available.
