DMS: Diagnostic Modeling System. Report 3. DMS Data Manager - A User's Guide

This report documents the development functionality, and application of the Diagnostic Modeling System (DMS) Data Manager, a Geographic Information System (GIS)-based software package to organize and examine dredging-related data. The DMS gives a rapid evaluation or diagnosis of a problem shoaling area and provides guidance for determining possible solutions. The economic lever underlying the DMS concept is that a low-level analysis, possibly supplemented by a modest numerical modeling effort, can yield substantial cost savings without interrupting ongoing O&M activities and schedules. That is, the DMS is intended to provide feasible alternatives for reducing O&M costs within the dredging cycle of the subject project The application time and effort in applying the DMS are proportional to the maintenance time of the project.
