Mine Burial by Local Scour and Sand Waves
Abstract
Our long-term goal is to help advance the U.S. Navy's capabilities for Mine Burial Prediction (MBP) by conducting large-scale laboratory observations that will both improve our knowledge of the physical processes involved in mine burial and provide a vital bridge between field experiments and numerical modeling of mine burial processes in shallow waters. The main objective of this effort over the past years has been the direct observation and monitoring of the burial process of various cobbles (model mines) induced by waves and the combined action of waves and currents. The experimental conditions have made it possible to observe the burial process due to both local scour around the mines as well as the passage of large sand waves. More recently, these rather unique observations, in addition to bathymetry and velocity measurements, are being used to test, validate, and calibrate numerical model predictions generated in FLOW-3D. Our aim by coupling the two approaches is to provide a more comprehensive study that focuses on turbulent intensities, characterization of horse vortex, and vortex shedding mechanisms which are of significant importance to the erosion, transport and deposition of sediment in the vicinity of the object. Ultimately, this work will aid in the development of a mechanistic model for Mine-Fluid-Sediment (MFS) interaction by the ONR Mine Burial Prediction Team.
