Evaluations of commercial mechanical monitoring systems were performed in 2008, and a pilot study was conducted on the Big Sandy River in Huntington District (beginning in 2012) to verify that data could be collected and transmitted in an efficient manner. Data such as bucket position, dredge position, and bucket status (dig/dump) were collected and correlations were made to estimate material quantities, advance and effective dredging times.
