Short description of the intervention
The Water of Leith is home to a wide diversity of plants and animals. The river performs an important flood control function in the city. A management plan envisions to create a healthy river that flows through a green corridor from the hills to the sea and is a haven for wildlife, is enjoyed and managed by the public, and is valued for its built and cultural heritage. The current intervention is about an extensive Flood Prevention Scheme. Walls and other flood defence measures have been constructed from Murrayfield downstream to Bonnington. A re-modelling exercise is being carried out to include the impact of climate change on the river system and the efficacy of the flood prevention scheme. The Water of Leith Conservation Trust works to conserve and enhance the river, its heritage and wildlife. It also promotes education and recreation and works with volunteers and community groups (ref 1, 2, 3).

Present stage of the intervention
Please specify "other" stage of the intervention
- Phase 1 of The Water of Leith Flood Prevention Scheme began in February 2011, and currently PHASE 2 Of the flood works at Murray field is underway and a section of the Walkway will be closed from 2016 to January 2018. (Ref 2)

- The management plan for the Water of Leith is designed to last for a ten-year period (2010 – 2020) (ref 1)
Goals of the intervention
The objective of the flood prevention scheme were,
1. to provide a higher level of protection to homes and businesses that are at risk of severe flooding events.
2. to manage the river to minimise flood risk and reduce the impact of flooding whilst mimicking natural flow variations.
3. to conserve and enhance the river, its heritage and protect the wildlife including, flood prevention, enhancing the river, heritage protection and conserving wildlife
4. to improve water quality.
5. to improve riparian morphology to meet Water Framework Directive good ecological potential in the water bodies within the catchment. (ref 1, 2, 3).
Quantitative targets
1. construction of flood defences over approximately 1.2 km along the Water of Leith at Murrayfield.
2. The Trust works with volunteers and community groups to deliver around 100 river clean-ups and habitat improvement tasks annually (ref 1, 3)
Monitoring indicators defined
Area of flood defence measures, times of river clean-ups by volunteers and community groups annually ( ref 3)

Implementation activities
The Flood Prevention Scheme Phase 1 and 2 are complete. It consists of the construction of flood defences over approximately 1.2 km along the Water of Leith at Murrayfield. Works included top-of-bank, reinforced concrete piled retaining walls which incorporate embedded steel sheet pile foundations that further reduce flood risk by controlling seepage during long duration storm events. As well as, enhancement of the river flow regime through the demolition of 4 bridges across the river and their replacement with two new road bridges and provision of an overflow channel to provide additional storage capacity. A two-stage channel and berm has been created. The Trust promotes education and recreation through the Visitor Centre, and works with volunteers and community groups to deliver around 100 river clean-ups and habitat improvement tasks annually. Community groups and local businesses are involved in many projects along the river including: River clean-ups, Invasive species removal, Path maintenance, Vegetation control, Removing log jams, Native wildflower planting, Creating education areas, Habitat creation projects (ref 1, 3, 5).
