Above which range should be the unit hydrographs be used? Correct Answer Around 5000 sq km
In practice, only a limited number of unit hydrographs are used for a given basin. It is also common practice to neglect the variations in rainfall distribution within the basin area. Hence it is not advisable to use unit hydrograph method for basins over 5000 sq km.
