Q.12-2008

• A new harbour is to be built at a new location. The suggested new location is either at a bay or a cape. Four models for the structure of the retaining wall are given. Table 12 below shows the location and the characteristics of the four retaining walls.

Page 6: PHYSICS  IS  FANTASTIC

Worksheet

Page 7: PHYSICS  IS  FANTASTIC

• Explain the best location and the suitability of each characterictics in Table12.

• Determine the most suitable retaining wall to be used.

• Give the reason for your choice.

Page 8: PHYSICS  IS  FANTASTIC

Answer Characteristic Explaination / reason

The ______ Water is calmer

______retaining wall.

Decrease the wavelength / higher water pressure at

higher depth.

______ surfaceReduce energy, wave is

reflected at different direction.

______ retaining wall

Protect form high wave / overflow of water.
