Figure 22. Lag created by a linear reservoir. INFLOW_5 peaks shortly after
60 hours while OUTFLOW_5 peaks near 75 hours. The difference in peak time
shows the lag created by the linear reservoir in that the inflow to the linear
reservoir (INFLOW_5) peaks before the outflow from the linear reservoir
(OUTFLOW_5). Furthermore, OUTFLOW_5 is much smoother than IN-
FLOW_5. The difference in smoothness is due to the storage of water within and
gradual release of water from the linear reservoir.

Figure 23. Behavior of the lag and route structure. INFLOW_2 peaks at
75 hours, OUTFLOW_2 peaks at 79 hours, and OUTFLOW_2_LAG peaks
at 84 hours. The difference in peak times among INFLOW_2, OUT-
FLOW_2, and OUTFLOW_2_LAG shows the effect of the lags located in
the lag and route structure because INFLOW_2 is the inflow to the linear
reservoir in the lag and route structure, OUTFLOW_2 is the lagged outflow
from the linear reservoir in the lag and route structure, and
OUTFLOW_2_LAG is OUTFLOW_2 lagged by three hours. The difference
in smoothness between INFLOW_2 and OUTFLOW_2 is due to the storage
of water within and gradual release of water from the linear reservoir in the
lag and route structure. The similarity in smoothness between OUT-
FLOW_2 and OUTFLOW_2_LAG is because OUTFLOW_2_LAG is the
value of OUTFLOW_2 delayed by three hours.
