Maximum depth of flooding over the flood plain in the last 20 years.
Any figures over 2 metres depth would over top the protection embankment.

Use the table below to set out your frequency calculations sorting the floods into 5 groups or classes.:
Group/Class (metres) Frequency
0.0 - 0.9  
   
   
   
   
Draw a histogram showing your 5 group frequencies. Clearly indicate which ones would have flooded the housing development.

Then write  a paragraph interpreting what this evidence tells us  to support your arguments against the proposed housing development.
