(hydrology)
The interval of time required for a quantity of water equal to the volume of a lake to pass through the lake outlet; computed by dividing lake volume by mean flow rate of the outlet.

The second stage (B) was a flushing period, which also showed a sharp decline in Darcian velocity, suggesting the decline of soil permeability.
The leaching process (or solute flushing period) was well simulated with CTRW and FADE in Figures 6-8.
It was found that Darcian velocity in the 8 cm column was less than that in the 3 cm and 5 cm columns and was relatively stable; that is, it remained nearly the same at the tracer introducing and flushing periods (Figure 2(a)).
It is interesting to see that the Darcian velocities in both the 8 cm smooth wall (Figure 2(a)) and rough wall (Figure 2(c)) columns were relatively stable; that is, they are nearly independent of time at both the tracer introducing and flushing periods.
It was observed that, the harvest yield decreased with increasing flushing period. Similar trend was observed by several investigators [23,37,1].
It is noticed that, the biological efficiency decreased with increasing flushing period. Similar trend was observed by Abeer et al.
It decreased also with increasing flushing period. The total bioconversion efficiency was 7.15% (Figure 5).
After a brief flushing period, a nearly clear parison is generally produced.
Doorenbos (1953) cites Goebel (1880) as noting that defoliation of a dormant twig during the spring "has been shown again and again to cause the terminal bud to resume growth." It has often been observed that natural defoliation due to herbivory or hailstone damage during the flushing period causes precocious opening of terminal buds (Romberger 1963).
The flushing periods for the 10 species ranged between mid-April and early June (Cline and Deppong 1999).
This down time is used for pruning and fertilizing the tea bushes in preparation for the heavier flushing period to come.
