How many people are at risk of flooding in the tees area
24,000
Since 2002 how much money was invested into flood management strategies
£11 million
4 types of hard engineering strategies
Flood gates
Embankments
The tees barrage
Cow green reservoir
Describe the floodgates used as a hard engineering strategy
Concrete walls
A barrier between the town of yarm and rising waters
Describe the embankments used as a hard engineering strategy
Added along the river to raise the banks
Therefore the river can hold more water

£54 million
What happens to the tees barrage now
Constantly kept at a high level
When was the cow green redevoir built
1970s
How long is the cow green reservoir
1/4 of a mile
How many litres of water does the cow green reservoir hold
40,000 million litres
What are the 2 types of soft engineering strategies used
Flood warnings
Flood plain zoning
Describe the use of flood warnings
Direct system
Set up to give people early flood warnings
Describe flood plain zoning
Discourage of building on low lying land to reduce future risk
flood management issues - positive social
Reduce levels of anxiety
Reduce levels of depression
flood management issues - negative social
Not all defences work e.g. there was a flash flood in Eston in 2017. This caused travel disruption.
Some people think sole of the defences are ugly
Flood management issues - positive economic
Dozens of businesses are now protected
Flood management issues - negative economic
Vast number of flood defences are £££ to maintain
Cost scheme about £54 million
Flood management issues - positive environmental
Creation of reservoir created aquatic habitats
28 environmentally designated sites at risk from flooding which need protection
Flood management issues - negative environmental
Flood walls are a barrier to some forms of wild life
People oppose cow green rés ovoid as it could damage habitats
