Measurement of Sewer Sediment Elevations
Paper i proceeding, 1987

In field investigations of the sedimentation process it is of interest to study the extension and thickness of deposits. At the department a method to determine the depth and elevation of sediment in sewers has been developed. The method enables measurement of deposits between manholes without disturbing it. In this way the long-term sedimentation can be studied at selected test sites.
