Seed was collected from local areas, germinated and grown on in Lincolnshire before being returned and planted on site making it one of the most well planned and managed local provenance planting schemes ever undertaken, including approximately 250,000 trees.
The scheme required the excavation of material from most of the 7 mile channel length. This material was reused to create two raised areas of land with panoramic views of the surrounding area including Windsor Castle. The raised areas are located in part on what was previously the sludge drying beds of Slough Sewage Treatment Works, This central location was used as a hub for the materials management in the scheme with the channel being excavated from each end towards the hub to avoid intensive use of the highways in the area. The channel and its margins in this area now form Dorney Wetlands, in a transformed landscape that is now a honeypot to people and wildlife.

River Flooding ( Edexcel GCSE Geography: B (1GB0) )
Revision note.
Geography Lead
Risks from River Flooding
- River floods are one of the most common natural hazards
- The risk from river flooding around the world has increased over the past 50 years
Graph showing the increase in flood events over time
- Deforestation
- Agriculture
- Urbanisation
- These all increase overland flow/run off and decrease the lag time
- The result is that the river's capacity is more likely to be exceeded leading to a higher flood risk
- Climate change may lead to increased rainfall or frequency of storms which increases the discharge
- River channel management upstream can increase discharge downstream for example straightening the channel will increase the speed the water moves downstream increasing the risk of the river capacity being exceeded
Impacts of increased flood risk
- There are a range of possible impacts of flooding
- These can be both social and environmental
Possible Impacts of Flooding
| Homes destroyed and damaged leading to homelessness | Destruction of animal habitats |
| Damage to crops and agricultural land which increases the chances of food shortages and food price increase | Loss of food supply for animals |
| Death and injury | Pollution of land due to pollutants such as sewage and diesel in the flood water |
| Damage and destruction of transport routes (road and rail) | Death and injury of animals |
| Loss of jobs due to the damage and destruction of businesses | Destruction of trees and other vegetation |
| Loss of clean water supply as contaminated water enters the supply | |
| Loss of electricity and gas when water gets into the supply |
Worked example
Explain one way in which human activity can increase the risk of river flooding.
- Building on floodplains/urbanisation (1) which can reduce infiltration and/or puts more people/property at risk (1)
- Deforestation (1) which reduces infiltration and so increases runoff making rivers ‘peakier’ (1)
- River channel management preventing river flooding upstream (1) so making river discharge larger downstream thus increasing risk (1)
- Climate change idea (1) increasing rainfall and/or making weather stormier increasing discharge (1)
Managing Flood Risk
- The key cause of flooding is the amount and duration of precipitation this cannot be altered
- There are a number of methods of managing floods and reducing the severity and/or impact
- Hard engineering involves building structures or changing the river channel
- Soft engineering works with natural processes of the river and surrounding environment
- Soft engineering is increasingly popular
- Soft engineering is an example of mitigation where schemes aim to minimise damage rather than trying to prevent the flooding
Cost and Benefits of Hard Engineering
| Enables the amount of discharge downstream to be controlled | Expensive to build Can affect habitats downstream | |
| Increase the capacity of the river Use natural materials which blend with the environment | May fail due to erosion or water overtopping Can be expensive Increase flood risk downstream | |
| Increases river capacity as it removes sediment from the river bed | Needs to be carried out regularly Increases flood risk downstream | |
| Allow some water to flow out of the main channel reducing the discharge and protecting areas in the immediate area | Can lead to flooding elsewhere | |
| Low maintenance Relatively low cost | Increases flood risk downstream Block the view of the river |
Costs and Benefits of Soft Engineering
| This supports the river by restoring it back to its original regime: putting meanders back in, stabilising banks and connecting to flood plains | It involves land use change that the local population may not want | |
| Areas are left undeveloped so that the floodwaters can flow on to them. This reduces discharge within the river channel | Reduces the land available for development and agriculture | |
| Means that only certain land uses are allowed on the flood plain, reducing flood risk Provides areas for leisure and recreation | Reduces the land for development and agriculture | |
| Reduces discharge by increasing infiltration and interception | Not possible in all areas |
- Leaving the stubble on the fields after the crop is harvested helps to stabilise the soil and increase infiltration
- Contour ploughing which involves ploughing fields across the slope rather than up and down. This gives the water more time to infiltrate and stops the ploughed furrows becoming channels for water
- Improved forecasting and flood warnings

The Jubilee River was built by the Environment Agency and opened in 2002. It is part of the Maidenhead Windsor and Eton Flood Alleviation Scheme (MWEFAS) and is a man made, 11.6 kilometre stretch of naturalistic river and habitats. The scheme reduces the risk of flooding to approximately 3,000 properties in Maidenhead, Windsor, Eton and Cookham.
The Jubilee River diverts river water from the River Thames upstream of Maidenhead, running parallel and to the north of the river, and rejoins the Thames downstream of Windsor.
Under normal conditions, the Jubilee River provides a local recreational and wildlife amenity. In flood conditions, water is diverted from the Thames and into the Jubilee River. This reduces flood levels in the River Thames running through Maidenhead, Windsor, Eton and Cookham.
Along the length of the Jubilee River are several weirs that keep water at levels similar to those experienced in the River Thames. The scheme also incorporates flood embankments to the north of Maidenhead and the west and north of Cookham.
The Jubilee River reduces flood risk to properties by increasing the total flood capacity of the channels flowing through the area. While it does not protect communities downstream of the scheme, it operates so that flood levels downstream are not adversely affected.
A short video has been produced that explains how the Jubilee River works. View it on the Environment Agency River Thames Waterways Team Facebook page .

Hard Engineering River Management
Hard engineering management of rivers involves the construction of structures, built to control the flow of water and reduce flooding.
Hard engineering river management involves the construction of structures built to control water flow and reduce flooding.
Dams and reservoirs
A large wall is built across a river, usually in the upper stages. The land behind the dam is then flooded, forming a reservoir .
The dam at Cow Green Reservoir, River Tees.
Reservoirs store a significant amount of water, which helps reduce the risk of flooding, particularly during heavy or prolonged rainfall. As water flows through the dam, it can be used to generate electricity. Storing water in reservoirs ensures a constant flow even during periods of dry weather.
Disadvantages
To create the reservoir, large areas of land need to be flooded. This can lead to people being displaced (having to move away). Dams are costly to create. Sediment , transported by the river from the upper stages, is deposited in the reservoir, reducing the river’s velocity. This means less sediment is deposited further down the course of the river, which could reduce soil fertility on the floodplain.
Straightening
Straightening involves changing the course of the river. This involves straightening the channel by cutting out meanders.
Channel Straightening
Straightening allows water to flow along the course of the river more quickly. This reduces the risk of flooding.
As water is travelling faster, there is an increase in the risk of flooding further downstream. In addition, as the water flows faster, the erosion rate will increase. Unless the river banks are reinforced, the natural flow of water will cause meanders to form again in the future.
Embankments
This involves building up the banks of the river. This could be by creating levees or building walls. The image below shows embankments at Cockermouth. They were created to reduce the risk of flooding.
Flood defences at Cockermouth
The river channel can hold more water, which reduces the risk of flooding.
Embankments are expensive to install. Also, if the embankment fails, the surrounding area will be rapidly flooded.
Flood relief channels
Flood relief channels are artificial channels created to divert water around or from important locations if a river is at risk of flooding.
Jubilee River flood relief channel
River discharge is reduced, which means the risk of flooding is decreased.
There will be an increased risk of flooding where the flood relief channel re-joins the river. If bankfull capacity is reached in the flood relief channel, it will flood the surrounding area.
