The effects of sea-level rise in Norfolk:

Settlements such as King's Lynn may be under threat as sea levels rise.
Valuable agricultural land (the Fens) will be at greater risk of flooding
The Norfolk Broads are a popular tourist destination bringing £5 million+ to the local area
Erosion rates are likely to increase, threatening coastal settlements such as Overstand and Happisburgh. Current sea defences will need strengthening, which will be expensive.
The Thames Barrier currently protects buildings worth £80 billion. It will probably need to be replaced in the next 30 to 50 years,
As sea levels rise, large areas of the Lower Thames estuary will be at risk from flooding, affecting housing, industry and farmland
Low-lying mudflats and marshes in Essex are particularly vulnerable to sea-level rise.
Areas of salt marsh are being squeezed between sea walls and rising sea
Some 22% of East Anglia's salt marshes could be lost by 2050
In some places, managed retreat (a controversial political decision) will breach sea walls to allow deliberate flooding so that salt marshes can reform
