1. Flood plain Management
Objective: classify human and physical causes of flooding
Starter: Look at the picture below...
Calculate the height of the flood water.
What would be affected at this height?
Outcome:
Identify and classify causes of flooding – Human and Physical
Practice interpreting news paper articles
Describe the effects of flooding on people and environment
Begin to identify how the effects of flooding can be reduced.

2. What difference does land use make?
LESS FLOODING
MORE
FLOODING
Write or stick the labels onto the appropriate part of this diagram.
Slow movement of water through drainage basin
Fast movement of water through drainage basin causes floods

3. Factors contributing to flooding page 93
Physical Factors
Human Factors
Intense
Rainfall
More than infiltration, increased surface run off
Deforestation
Less soil storage or plant use, increases surface run off
Snow melt
Spring snow melt causes large volumes of water
Urbanisation
Impermeable surfaces such as concrete and tarmac
Impermeable
rock
Some drainage basin have rocks such as granite which do not allow infiltration (Boscombe)
Climate change
Increased temps – melting ice, more storms

4. Impacts of Flooding – Using Sources
Exams use news articles - Read the article
Australia is experiencing very heavy rain, what else has increased the severity of the flooding?
Consider the effects of the Australian floods
Effects on environment
Effects on people
Damage to marine ecosystems by fresh water e.g. Great barrier coral reef
Loss of soil affects money made from crops and farmland
Pesticides wash off the farm land into the sea
Loss of tourism due to reef damage and environment damage
Environmental
Economic

5. Effects of flooding on people and environment
Copy the two diagrams on page 94
Effects on people
Effects on Environment
Answer the exam question on page 94
Read the news report on flooding in Wales in 2008
What caused this flooding
Identify three impacts
How did the fire fighters cope?

6. Prediction and prevention of the effects of river flooding
Forecasting
monitor rivers (environment agency),
Warn people of risk and evacuate people,
map areas at risk of flooding,
Building Design
Have tiles floors not carpets
Raise height of sockets above 1.5m
Fit stainless steel or plastic kitchens (not chipboard)
Fit boilers upstairs
Planning
Don’t build in high risk areas, or use it for recreation – Land zoning

7. Education Preparation Local authorities post leaflets to residents
Advertise information on TV and radio
Website
Helpline
Drills and training exercises
Preparation
Adapt your house
Discuss and evacuation plan
Store drinking water – in containers or bathtubs
Keep a stock of food (no fridge or cooking required)
First aid kits
Disaster kit – Rubber gloves, radio, torch, batteries, can opener

8. H/W Check the flood information for the River Tees, Darlington
Check the flood information for the River Tees, Darlington
Create a leaflet that could be distributed to houses at risk of flooding in this area
Explain what they should do before, during and after the flood.
