Which of the following formula for calculating yield can be applied to all catchments?

(a) Inglis formula

(b) Khosla’s formula

(c) Lacey’s formula

(d) Barlow’s table

The question was asked during an interview for a job.

My question comes from Reservoir Capacity Determination Using Hydrograph and Mass-curve topic in portion Reservoirs and Dam Reservoirs Planning of Irrigation Engineering

Correct option is (b) Khosla’s formula

For explanation: Khosla formula is based upon the recent research work conducted in the field. It is a simple and useful formula and can be applied to the entire country. The formula is given as-

Yield (Q) = P – 0.48 Tm where Q = the yield in cm, P = rainfall in cm, and Tm = mean annual temperature of the area.
