Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Continuous Deformation Monitoring System (CDMS)

reportActive / Technical Report | Accession Number: ADA261833 | Open PDF

Abstract:

The US Army Topographic Engineering Center TEC has developed an automated deformation monitoring technology known as the Continuous Deformation Monitoring System CDMS. The CDMS is capable of computing structural deformation using the Global Positioning System GPS survey technology while operating in a continuous fashion over time. A network of two personal computers control GPS survey equipment and process the satellite data gathered to compute apparent structural deformation up to 24 times a day without the presence of an operator. Structural monitoring can take place at the project site or at a distant office. Performance testing by TEC has determined deformation measurement precision in the subcentimeter range. The CDMS was installed at Dworshak Dam in northern Idaho and tracked the upstream movement of the dam while undergoing reservoir drawdown.
