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.
Worksheet
• 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.
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.
