Plans for the biggest flood relief scheme ever undertaken in Ireland will go on public display in Cork today.

It is expected to cost between €40m and €60m to complete.

The Office of Public Works said the plan will provide protection, but will not remove the threat of flooding completely.

Work on the project is expected to begin in 2016 and will take three to four years to complete.

It involves the construction of flood defence barriers, the development of a flood forecasting system and changes to flood management protocols at the ESB's Inniscarra Dam.

Provision is also being made for the flooding of land between the Inniscarra Dam and Cork city.
