| Abstract: | The measurement principle and the mainly components of a dynamic measuring system for sediment concentration and flow rate determination are simply described, including four subsystems such as: the automated sampling subsystem, automated measuring and acquisition subsystem, data analysis/output/retrieve subsystem and operation/control subsystem. Laboratory application experiments and tests of the integrated system indicate that the system has such unique capabilities as short time for high precision measurements, and fast transmission of logged data. The system is so designed that it can be used not only for measuring sediment concentration and flow rate in the laboratory experiments of soil erosion study, but also for field research and for on-site long-term monitoring of soil and water loss from runoff plots. |
