Environmental sensitivity study on mine impact burial prediction model

Abstract

The Navy's Impact Burial Prediction Model creates a two dimensional time history of a bottom mine as it falls through air, water, and sediment. The output of the model is the predicted burial depth of the mine in the sediment in meters, as well as height, area and volume protruding. Model input consists of environmental parameters and mine characteristics, as well as parameters describing the mine's release. The model user seldom knows many of these parameters, and those that are known may be of questionable precision. In order to determine which parameters had the greatest effect on the model and which could be simplified or eliminated, a series of sensitivity tests were performed. It was found that the model data ingest could be greatly simplified without sacrificing accuracy too much. However, several parameters including sediment shear strength were found to have a large effect on the model and were investigated flirter.
