Question

A sequent peak algorithm is a plot between __________________

(a) Accumulated flow v/s time

(b) Discharge v/s time

(c) (Cumulative Inflow – Cumulative Outflow) v/s time

(d) Mass outflow v/s time

The question was posed to me at a job interview.

I'm obligated to ask this question of Reservoir Capacity Determination Using Hydrograph and Mass-curve in section Reservoirs and Dam Reservoirs Planning of Irrigation Engineering

Answer 1

The correct choice is (d) Mass outflow v/s time

Explanation: It is a plot between time on X-axis and cumulative net flow on Y-axis. It is an excellent alternative to the mass-curve method of determining reservoir capacity. The positive value of cumulative net flow indicates a surplus of inflow and a negative value indicates a deficit of inflow.
