Lincshore Project

Shortlisted schemes Civil Engineering

Lincolnshire, north of the Wash, has one of the most exposed soft coastlines in Britain. And behind 24km of sea defences lie three major towns and 200km2 of agricultural land lying about 2.5m below high tide level.

After the disastrous floods of 1953 extensive concrete sea walls were constructed and further breaches avoided. But continuing natural erosion of the sandy beaches was beginning to expose the walls to the full force of the North Sea. After extensive studies a more natural defence scheme was developed involving placing over 7.6M.m3 of material in front of the walls to enlarge the beach. Carefully selected sand was dredged from the sea off the lee end of the eroding beach, pumped ashore and contoured by dozers at low tide.

Integral with the scheme is long-term maintenance plan for the beach which will be carefully monitored and re-nourished as necessary in perpetuity.
