Question

Yield of a reservoir represents ___________________

(a) the inflow into the reservoir

(b) the capacity of the reservoir

(c) the outflow demand on the reservoir

(d) the optimum value of catchment yield

I had been asked this question by my school teacher while I was bunking the class.

The above asked question is from Reservoir Capacity Determination Using Hydrograph and Mass-curve in portion Reservoirs and Dam Reservoirs Planning of Irrigation Engineering

Answer 1

The correct choice is (c) the outflow demand on the reservoir

Best explanation: The yield of the catchment is the long-range runoff from a catchment. It helps in designing the capacity of the reservoir. The outflow from the reservoir (reservoir yield) is represented by the mass demand line.
