Monitoring of Maroon's Earth Dam Using Geotechnical and Geodetic Observations

Geodetic and photogrammetric mapping systems and methods can''t meet all the requirements of the displacement measurements. Hence، to collect information on local deformation، geotechnical and non-geodetic instruments are used within the deformable body. Geotechnical instruments such as extensometer، tiltmeter، inverted pendulum، and other similar devices can be used to gather continuous data. Definitely، by combination of geodetic and geotechnical measurements and by implementation of a comprehensive analysis of displacement، we can obtain better results in the monitoring of large structures such as dams. In this paper، the results of geodetic measurements (microgeodesy observations) of Maroon Dam have been compared with the results of geotechnical observations.
