Broadlands Flood Alleviation Scheme, River Yare, Great Yarmouth
- Embankment raised and seaward face protected with 150mm OSA on geotextile
- Surface covered with topsoil to encourage plant growth
- Monitoring of structural and environmental performance
Successful performance lead to the contract for Phase 2
Phase 2 (1999) Strengthening of embankment to front and behind existing sheet piled wall
The existing seaward revetment was made of old paving slabs and concrete, with serviceable gabion mattresses below. The area between the mattresses and the sheet piling had to be replaced, but removal of existing materials presented an irregular profile with voids at the top of the mattresses.
