Abstract
In this study, a sediment rating curve for the Ganges river at Hardinge bridge gauge station has been developed by establishing power relations between sediment transport as dependent variable and discharge and unit stream power as independent variables separately. The unit stream power used as independent variable gives an improved curve. The sediment rating curve improves significantly when it is developed by partitioning the data into rising, flood and falling limbs.
