Abstract : This report presents an analysis of benefits attributable to the Dredging Research Program (DRP). Each product developed by the DRP was catalogued. Each operation and maintenance dredging project was analyzed to determine whether a DRP product has been used or could be used on that project. The project was estimated. The benefits were categorized as direct, cost avoidance, environmental enhancement, mission enhancement, and other indirect benefits. These benefits were arranged into a database. Due to uncertainty associated with each benefit estimate, each benefit estimate was assumed to follow a specific probability distribution. The sum of all benefits was then subjected to a Monte Carlo analysis and the relative frequency histogram of the final sum of all benefits was calculated. There is a 0.90 probability that the DRP will provide benefits of at least $100,586,000 from 1994 through 1998. Based on one-time noncyclical project benefits that were not included in that number, it is probably understated by 100 percent. (AN)
