Flood Management Scheme – Boscastle

A flood management scheme following the 2004 floods.

Why the Boscastle flood scheme required?

On the 16th August 2004, a devastating flood swept through Boscastle, a small village on the north Cornwall coast.

Very heavy rain fell in storms close to the village, with over 60mm of rainfall in two hours. The ground was already saturated due to above average rainfall during the previous two weeks. Combined with this the drainage basin has many steep slopes and there are areas of impermeable slate that led to rapid run-off. Boscastle is at the confluence (where tributaries meet) of three rivers – Valency, Jordan, and Paradise. About two billion litres of water then rushed down the valley straight into Boscastle within a short space of time causing the rivers to overflow. Additionally, the deluge of water coincided with a high tide.

As the flood happened so quickly local residents had little time to react. Cars were swept out to sea and buildings were badly damaged. Thankfully, no one lost their lives, which is largely due to a huge rescue operation involving helicopters. Million of pounds worth of damage was caused by the flood.

What was the management strategy?

In 2008 a flood management scheme for Boscastle was completed. The solution included both soft and hard engineering strategies.

The Environment Agency has made a considerable investment in flood defences in Boscastle to help prevent a similar flood happening in the future. Working with professional partners, more than £10 million of improvements were carried out. This included widening and deepening the Valency River, and installing a flood culvert to improve flow in the Jordan River.

The Met Office and Environment Agency have formed the first of several working partnerships, the Flood Forecasting Centre. Combining expertise in weather forecasting and hydrology has helped to prepare communities for flooding during times of extreme weather.

At the time of the floods, the operational forecast model had a resolution of 12 km, which was too large to be able to represent such a small scale collection of thunderstorms. Since 2004 the Boscastle case was re-run with a higher resolution research model which proved able to resolve the line of thunderstorms with much more accuracy and detail.

What are the social, economic and environmental issues?

Social issues.

The rebuilding projects and construction of flood defences took several years which meant the lives of local people were disrupted for sometime. The risk of flooding has been reduced making Boscastle safer. The defences would not protect against a flood the same size as the one in 2004. The new bridge is not popular with local people as it is out of character compared to the rest of the building.

Economic issues

The risk of flooding has been reduced. Therefore, there is less risk of damage to property and businesses. The flood-defence scheme cost over £4 million. However, the scheme could have been significantly better, though some options were too expensive.

Environmental issues

Biodiversity has improved as have the river habitats. Vegetation in the area is now managed.

Case Study – Boscastle Floods

Floods devastate village.

On 16 August 2004, a devastating flood swept through the small Cornish village of Boscastle.

Very heavy rain fell in storms close to the village, causing two rivers to burst their banks. About two billion litres of water then rushed down the valley straight into Boscastle.

Residents had little time to react. Cars were swept out to sea, buildings were badly damaged and people had to act quickly to survive. Fortunately, nobody died – thanks largely to a huge rescue operation involving helicopters — but there was millions of pounds worth of damage.

Physical Impacts

Responses to the flooding, what happened to cause this event.

Flooding On the day of the flood, about 75mm of rain fell in two hours — the same amount that normally falls in the whole of August. Huge amounts of water from this sudden downpour flowed into two rivers, the Valency and Jordan (which flows into the Valency just above Boscastle). Both overflowed, and this caused a sudden rush of water to speed down the Valency — which runs through the middle of Boscastle.

Destruction of houses, businesses and gardens Floodwater gushed into houses, shops and pubs. Cars, walls and even bridges were washed away. The church was filled with six feet of mud and water. Trees were uprooted and swept into peoples’ gardens. The weight of water eroded river banks, damaged gardens and pavements.

Human Impacts There was a huge financial cost to the floods. This included:

  • the rescue operation – involving helicopters, lifeboats, and the fire service.
  • the loss of 50 cars
  • damage to homes, businesses and land
  • a loss of tourism, a major source of income for the area

The flooding also had several other key impacts on Boscastle and its inhabitants. These included:

  • environmental damage to local wildlife habitats
  • coastal pollution caused as debris and fuel from cars flowed out to sea.
  • long-term disruption to the village, as a major rebuild project had to be carried out.
  • long-term stress and anxiety to people traumatised by the incident.
  • John Prescott, the Deputy Prime Minister, and Prince Charles visited members of the emergency services and the local GP surgery, which acted as the emergency centre, in the days following the disaster.
  • Prince Charles, who is the Duke of Cornwall, made a large donation to a fund to help rebuild parts of Boscastle.
  • The Environment Agency is responsible for warning people about floods and reducing the likelihood of future floods. The Environment Agency has carried a major project to increase flood defences in Boscastle, with the aim of preventing a similar flood happening again.
  • We are investing in new ways of predicting heavy rainfall events on a small scale to produce better warnings.

3.13 Case Study - Boscastle Floods (2004)

Flash floods occurred in the valleys of the River Valency and the River Jordan on 16th August 2004.

The village of Boscastle is situated:

in a narrow valley with interlocking spurs which acted like a funnel

in a steep valley which encouraged rapid run-off

on a flat flood plain

in an area where the soil is impermeable clay which does not allow much infiltration

185 mm if rain fell in five hours

The soil was saturated from recent rainfall so no more rain could infiltrate

The collision of winds on a very warm day caused the excessive rainfall (the air mass from the south met the air mass from the south-west and converged on Bodmin which led to towering cumulonimbus clouds. The air was very unstable and the clouds were up to 10 km high).

The natural channel of the river had been walled (for the construction of the B3263 and a pedestrian area) which prevented it from adjusting to a variation in the discharge of the water.

The village had been built on a flat flood plain.

There was no flood control system.

Cars, trees and boulders became stuck under the bridge and created a temporary dam which caused the water to build up behind it.

The sewers and drainage systems were old and small in capacity; they broke and the water that was in the, took an overland route.  

50 cars were swept into the harbour.

The bridge was washed away and roads were submerged under 2.75 m of water, making communication difficult.

The sewerage system burst.

For health and safety reasons Boscastle was declared inaccessible. 

The Museum of Withcraft lost 50 per cent of its artefacts.

Four buildings were demolished and 58 flooded and the High Street was badly damaged.

 The visitors' centre, a clothes shop and two gift shops were badly damaged.

The youth hostel was flooded.

People were in shock and there were concern about hypothermia or being swept away.

There was no power in the village for some time (an emergency generator had to be blown in). 

90 per cent of the economy in Boscastle is based on tourism and there were still three weeks of the summer holidays left; twenty accommodation providers were shut.

Visitors whose cars had been washed away were not able to leave.

A speedy, well-co-ordinated and well-resourced rescue operation ensured that remarkably there was no loss of life. Even by the standards of developed countries, this was outstanding and a tribute to Britain's rescue services.

Emergency workers rescued residents and holiday-makers from a 32 km stretch of the north Cornwall coast.

Hundreds were evacuated from homes, rooftops (120 from rooftops), trees and vehicles.

Seven helicopters from the Coastguards, Royal Navy and RAF were used.

People took emergency shelter in The Rectory, which was on high ground. 

The village was cordoned off by building inspectors for the clean-up operation.

People dug out guttering and removed rubble so that the water could flow away.

Sandbagging was used as a form of defence.

People came to see the catastrophe.

Prince Charles and the Deputy Prime Minister at the time, John Prescott, came to see the damage.

There was a church service to give thanks that no one had died.

The repairs were very costly and time consuming.

There was a huge fund-raising effort to help rebuild the village.

Insurance is now costlier in Boscastle. 

Flood Control and Prevention

The Environment Agency carried out a major investigation.

A £2 million grant was given to Boscastle to help with flood prevention.

No more schools or old people's homes are built in the valley.

The Environment Agency removed debris from upstream, which meant there was more room for the water to flow freely under the new bridge.

A flood defence system (building a flood wall, widening the River Jordan, raising car parks, removing bridges and using relief channels) was planned and is now complete. This also included building a high-arched single-span bridge which would not impeded flood water debris.

River Management Case Study - Boscastle

What caused the 2004 boscastle flash flood.

On the 16 th of August 2004, there was a flash flood in Boscastle (in Cornwall).

Illustrative background for Removal of vegetation

Removal of vegetation

  • The removal of trees and vegetation upstream of Boscastle increased surface runoff.

Illustrative background for Steep relief

Steep relief

  • Boscastle is in a very steep valley, which means surface runoff is high and fast.
  • The steep valley acted like a funnel, channeling all of the rain into Boscastle.

Illustrative background for The low bridge in Boscastle

The low bridge in Boscastle

  • A bridge over the River Valency in Boscastle was not very tall and had a low arch.
  • When the flash flood came, cars and debris became stuck under the arch creating a dam. This led to even worse flooding.

Illustrative background for Intense rainfall

Intense rainfall

  • 200mm of rainfall fell in 24 hours (the monthly average was 75mm).
  • Between 50mm and 100mm fell in the space of a few hours.
  • July and August 2004 had been rainy, so there was already a lot of surface runoff.

Illustrative background for Lack of flood defences

Lack of flood defences

  • Boscastle had no flood defences. This meant that it was vulnerable to any especially heavy rainfall.

Consequences of the Boscastle Flash Flood in 2004

There were immediate and long-term consequences of the Boscastle flash flood that happened on 16th August, 2004. These consequences included:

Illustrative background for Decreased tourism

Decreased tourism

  • The flood happened during the peak season for tourism.
  • People think that the flood cost the town £50 million in damage and lost income.

Illustrative background for Flood damage

Flood damage

  • 58 properties were flooded. 4 of these were destroyed.
  • 150 cars were swept away.
  • Roads and bridges were destroyed.

Illustrative background for Evacuation was difficult

Evacuation was difficult

  • Evacuation was difficult because the flooding happened so fast.
  • 100 people were airlifted to safety.

Illustrative background for Environmental pollution

Environmental pollution

  • Environmental pollution happened as a result of about 150 cars being transported by the floodwater into the sea. 30 cars were swept out to sea.
  • 1,850 tonnes of flood debris were recovered from the surrounding area.

Illustrative background for Illness and injury

Illness and injury

  • Nobody was seriously injured. Most of the harm was due to stress and mental health.

Responses to the Boscastle Flash Flood in 2004

There were immediate and long-term responses to the Boscastle flash flood that happened on 16th August, 2004. These responses included:

Illustrative background for New bridge with a higher arch

New bridge with a higher arch

  • Increasing the height of the bridge's arch should stop the bridge from becoming a dam if flooding happens again.

Illustrative background for Deeper and wider river channel

Deeper and wider river channel

  • A new £10 million pound scheme tried to stop this happening again.
  • The River Valency was widened by 3 metres and lowered by 2 metres.
  • 3 gauges were introduced to monitor water levels.

Illustrative background for Rebuilding

  • Buildings and roads had to be rebuilt.

Illustrative background for Emergency rescues

Emergency rescues

  • Nobody died.

Illustrative background for Temporary accommodation

Temporary accommodation

  • People whose accommodation got flooded were put up in temporary accommodation.

The Boscastle flood of 2004 – A case study of cause, effect and response

Using the Teachit Geography template, this sorting exercise provides a framework for investigating cause of, effect of and response to the 2004 Boscastle flood.

Extract from the resource: 

The flood on 16 August 2004 in Boscastle in Cornwall was the worst in local memory and an Environment Agency report concluded that it was among the most extreme ever experienced in Britain.

There was a combination of human and physical causes contributing to a series of effects and impacts.  The responses to the flood were both short and long term. Sort statements to show these causes, effects and responses, e.g. loss of businesses, water gauging stations were installed, Boscastle is at the confluence of three rivers, etc.
