I am now going to look at one human activity in more detail and demonstrate
how building embankments has the potential to cause more damage than
letting the river flood naturally.

Protection, control and preparation for the future

Too much human interference in a natural system such as the Rhine can
make flooding worse. The following table highlights the advantages and
disadvantages of several flood protection, control and preparation schemes.

         Flood control diagram (8)
         The Mississippi River in the USA sometimes floods. Engineers
         have attempted to control these floods by building
         embankments (X) ands canals (Y) as shown in the diagram.
             Explain how these two methods control the flooding. (4)
             Suggest why embankments and canals are not always
              effective in controlling flooding at W. (2)
             Why might people living at Z be concerned about these
              flood control methods upstream? (2)
