Langeveld, J.G. Clemens, F.H.L.R. Faculty Civil Engineering and Geosciences Department Water Management Date 2014-09-07 Abstract There is still a long way to go in understanding the behaviour of solids in sewers due to the difficulties in obtaining sufficient monitoring data to be able to understand the dominant processes. Laser profilers have shown to be capable of measuring the pipe interior, with a high accuracy, which is sufficient to be able to detect and quantify wall losses. This paper describes the potential of laser scanning for measuring sediment volumes in sewers. In addition, the propagation of uncertainties from laser measurements to sediment volumes are discussed, with special attention to conditions that could affect the measurements. The Laser profiler has shown to be capable of measuring the pipe interior, which is sufficient to be able to detect and quantify sediment volume. Overall, this research is a first step in defining a new inspection concept that will be able to give reliable information on relevant failure mechanisms.
