Pseudocylinder Parametrization For Mine Impact Burial Prediction

The United States military has undergone numerous changes since the end of the Cold War. Specifically, the U.S. Navy experienced a shift in the area of engagement from the “blue water” (water depth greater than $100m$⁠) to littoral regions of the world. The sea mines become the big threat in the naval operations. Within the past $15years$ three U.S. ships, the USS Samuel B. Roberts (FFG-58), Tripoli (LPH-10), and Princeton (CG-59) have fallen victim to mines. The total ship damage was $125 million while the mines cost approximately $30 ,000 (1).

Let $(x,y)$ be the horizontal coordinates and $z$ the vertical coordinate. A two-dimensional model (called IMPACT28) was developed to predict the mine’s movement in the $(x,z)$ cross section (2). The model contains two momentum equations (in $x$ and $z$ directions) and one moment...
