Fig.3. Spectra of water-surface elevation and current, 1-m depth
Figures 4 and 5 respectively plot the water level and velocity along the basin at hourly
intervals for the first 12 hr after the start of Day 1. Because the motion of the water level
and current are complicated (Fig. 2), changes at a fixed time interval are not regular. The
water level fluctuates between about 0.4 m, and the velocity fluctuates between about 0.4
and -0.3 m s-1 for this particular 12-hr interval. At the location L/2, η is anti-symmetric and
from a straight line that might be expected intuitively.
