Particles will float to shore, drift out to the ocean or absorb chemicals from the water, which weigh the particles down and cause them to sink to the bottom of the lakes.
Figure 10 shows the cyclic shear-drift responses of the coupling beam specimens.

Figure 11 shows the envelopes of the cyclic shear-drift response curves for the four coupling beam specimens.
The numerical model results were calibrated with the experimental results in terms of shear-top displacement (Fig. 8b), shear-drift envelopes (Fig. 8c) and energy dissipated (Fig. 8d).

In 1989, a damage index based on a shear-drift curve was developed by McCabe and Hall (1989), in which drift during and after an earthquake was used to evaluate the damage assessment of a structure.
The method minimizes structural weight with constraints on torsion, flexural strength, shear strength, drift, and openings and accessibility.
Demand parameters such as base shear and drift ratio are studied for varying heights of water in channels and different soil conditions at the site. .
