Abstract
In order to provide efficient Mine Countermeasures (MCM) with change detection, an appropriate interval between sonar surveys must be determined. Inadequate time intervals between resurvey can result in false alarms in the change detection process, or additional and unnecessary cost of performing routine surveys too frequently. In the event of an object identification alarm, an investigation must be performed thus prompting the effort in creating a cost effective and accurate method of determining the time scale of the seabed changes likely to cause false alarms. This Reference Document examines the use of open source software named XBeach for measuring seafloor activity. This includes tabulated information related to the MATrix LABoratory (MATLAB) toolbox and the methods of performing simulations using the XBeach software. The XBeach visualization simulations provide engaging imagery of sediment transport plotted over a world coordinate system. It was determined that the morphological simulations could provide insight into the seabed activity associated with the modeled locations. The opportunity exists to optimize routine survey scheduling and reduce false alarms associated with change detection through the aid of XBeach. XBeach software is a cost free solution that can reduce costs associated with performing routine survey assignments. Ultimately, the information acquired from XBeach should be integrated into survey planning tools for repeat seabed surveys in tactically si
