If the rainfall distribution in the storms is similar with respect to time and area, the ordinate of each hydrograph will be proportional to volume of runoff. The unit hydrograph is a hydrograph with a volume of 1cm runoff resulting from a rainfall of specified duration and a real pattern.

Generally 1cm or some cases 1inch or 10 mm.

So answer is between 10mm- 25mm. Therefore, the correct answer is 20mm.

@All.

The term Unit here refers to a unit depth of rainfall excess which is usually taken as 1 cm.

Can I get explanation for this question please ?

I think it will be 10 mm.

PIYUSH SINGH said:   1 decade ago
Answer should be 10 mm or 1 cm as Unit hydro graph produces runoff of 1 cm.

Unit hydro graph produces runoff of 1 cm that means 10mm.
