A rating curve will need to be completed to measure the water level to flow rates to achieve a discharge curve.
Using statistical analysis and regression functions, they found that the best fitted rating curve for all the stations estimated the sediment value more than the observed one and did not improve the classified information involving time, discharge and sediment values and flow separation by the means of correction coefficient of rating curve.
studied the suspended sedimentation in one of southern Algiers' watersheds and used the optimum rating curve achieved by the classification of the discharge values based on the flood season in order to estimate the sedimentation rate of flood events without precipitation graphs and sampling.
For study relation between discharge and sediment rate, the sediment rating curve was made (Fig.

Coefficients determination should be based data from a long-term period; otherwise, the sediment rating curve data would be excessively scattered [6].

It is also used to estimate storage requirements; compute outlet rating curves with tail water impacts; and analyze interconnected ponds with multiple outfalls and bi-directional flow.
This program uses HDS-5 methodology to compute headwater elevations and rating curves for submerged or unsubmerged culvert inlets and outlets operating under inlet or outlet control.
