Venice, Italy, is slowly sinking, so now, especially in
winter, plazas and walkways are fl ooded during storms.
The proposed solution is the fl oating levee of Fig. .
When fi lled with air, it rises to block off the sea. The levee
is 30 m high, 5 m wide, and 20 m deep. Assume a uniform
density of 300 kg/m 3 when fl oating. For the 1-m sea–
lagoon difference shown, estimate the angle at which the
levee fl oats.

It is desired to have a bottom-moored, floating system that
creates a nonlinear force in the mooring line as the water
level rises. The design force F need only be accurate in the
range of seawater depths h between 6 and 8 m, as shown in
the accompanying table. Design a buoyant system that will
provide this force distribution. The system should be prac-
tical (of inexpensive materials and simple construction).
