FLOODING AND FLOOD TYPES 7

What is a flood? 8 A flood is when water covers land that is not normally covered. Flooding is a natural event. Climate change means that we may see more floods in the future. Land and property need to be protected against flooding. Land and property need to be protected against flooding. Flood awareness is needed to know what to do in the event of a flood. Flood awareness is needed to know what to do in the event of a flood.

Fluvial (River) Fluvial flooding is flooding from rivers large and small. This happens when there is a lot of rainfall and sometimes if rivers are linked to the tides of the sea. The floods happen when the rivers burst their banks. 9

Coastal Coastal flooding usually happens during storm surges or very high tides and sometimes tsunamis. These high sea levels can breach coastal flood defences leading to flooding inland. 10

Pluvial (Rain) Pluvial flooding happens when there is a lot of rainfall in a short space of time with nowhere for it to go. This is also known as flash flooding or surface water flooding. This can lead to floods in urban areas and on roads. 11

Reservoir Reservoir flooding happens when the reservoir structure fails to keep the water in, either through cracks or complete destruction. The land beyond will flood as a large volume of water can escape at once. 12

Groundwater Groundwater flooding happens when the rocks and earth below the surface fill up with water which rises above the surface because it is waterlogged. This happens after long periods of heavy rainfall and can last for a long time. 13

FLOOD PROTECTION & DEFENCES 18

Flood Protection Activity We can’t change the weather! So we have to protect against flooding by having defences of different shapes, sizes and costs. Use your workbook to find out about different types of flood defences. Fill in the activity cards in your groups. 19
