The hydrology and water quality of runoff events were measured on gauging station and the runoff plots in the watershed and the rules of runoff, sediment, nitrogen and phosphorus load were analyzed.
This paper uses the sediment rating curve to simulate the sediment flux on the basis of on-site measured SSC and published values from the Datong Hydrological Gauging Station for the past 40 years.
These two methods were used at Tongguan hydrometric station to test flow and sediment forecasting and the results computed have shown efficiently improved accuracy of prediction.
