The recession curve of a hydrograph is sometimes referred to as the depletion curve because it represents the gradual decrease in streamflow as water is released from storage in the watershed, such as in soils, groundwater, and surface water bodies. This curve illustrates how quickly the available water is depleted after a precipitation event or runoff peak, highlighting the rate at which the watershed loses its stored water. Essentially, it captures the dynamics of water movement and storage depletion over time, reflecting how the hydrological system responds to changes in water input and output.
