asked Aug 25, 2023 in Irrigation Engineering by Carter (75.2k points)

Design yield of a storage reservoir is kept _______________

(a) higher than its firm or safe yield

(b) lower than its firm or safe yield

(c) equal to its firm or safe yield

(d) higher or lower than the firm yield depending upon the designer’s intuition

The question was posed to me in an international level competition.

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

The correct answer is (b) lower than its firm or safe yield

The explanation: An intermediate dependability percentage such as 50% to 75% is used to compute the design yield or dependable yield. This value will depend upon the risk which can be absorbed for the proposed use of water.
