Soft Engineering - River
Quaggy Restoration Scheme
1 Project
1.1 River runs through London since 1960's
1.2 Had been heavily managed with
artificial channels and culverts to
divert river beneath Greenwich
1.3 Increased flood risk from increased
urbanisation in Lewisham and Greenwich
mean more needed to be done in order to
protect these areas
1.4 Hard engineering methods where
considered but EA chose a more
sustainable approach
1.5 Solution was proposed by QWAG -
Quaggy Waterways Action Group

cutting a new channel thought Sutcliffe park
creating a multi-functional space, improving the

2.1 Created a wetland environment with reed banks, wild
flower meadows and trees.
2.2 Creation of new habitats
2.3 Enter text here
2.4 Scheme won Natural Environment
Category in the 2007 water ways
renaissance awards
2.5 smaller opportunity cost
3 Effectiveness
3.1 Long term sustainable scheme
3.2 Relatively low cost in comparison to other hard engineering schemes
3.3 little maintenance costs
3.4 Areas has not experienced any major flood
event since the project was completed
3.5 Reduced risk for 600 homes and
businesses
