Question

How to calculate runoff from rainfall data?

Answer 1

Calculations of direct runoffhydrograph in catchment due to a given rainfall event (with recordedrainfall values), is easy if a unit hydrograph is readily available. Remember that a unit hydrograph is constructed for a unit rainfall falling for a certain T-hours, where T may be any conveniently chosen time duration.

hope it helps!!
