1 3. ABSTRACT (Maximum 200 words) 



This report documents a case study at East Pass, Florida, to assess the concepts and performance of the Diagnostic 

 Modeling System (DMS), which is presently under development. The DMS is intended to give the capability to identify, 

 categorize, and evaluate navigation channel sediment-deposition hot spots, from which the system can be applied to identify 

 corrective actions and perform the appropriate analysis. The level of corrective measures are expected to be within existing 

 project authorization, and the diagnostic procedure should be capable of arriving at solutions to shoaling problems within the 

 project dredging cycle. The system consists of three components: the DMS-Data Manager, the DMS-Manual, and the 

 DMS-Analytical Toolbox, which are described in this report. 



The objective of the case study was to apply DMS concepts and available tools to determine the causes of shoaling in three 

 maintained channels at East Pass Inlet and to recommend solutions to reduce the frequency and cost of dredging. The DMS 

 evaluation led to such potential solutions, indicating the viability of the diagnostic method.
