What is meant by term ‘MAGNITUDE’ of a flood?  Size of flood  Volume of water discharged

Summarise the information shown in Fig 1 Infrequent Frequent As the discharge increases does the predicted return period.

Summarise the information shown in Fig 1  General Trend?  Any grouped data?  Specifics?  Many just getting the general trend = 1 mark

Describe the features shown in Fig 2 Meander Floodplain Buffs Levees Valley Sides Point Bar A DRAINAGE DITCH – NOT AN OX-BOW LAKE!

DESCRIBE the landforms shown in Fig 2  Meanders are bends or curves in the river  Floodplain is a wide flat expanse of land  Levees are built up banks that run parallel to the river…and so on!  You only need TWO!  Many writing more or not even describing – more explaining going on.  Also people describing the way the river runs through the picture and the vegetation! NOT NEEDED!
