Adaptive Management Approach
An adaptive management approach should be adopted now, whereby the new defence structures are built with their foundations and layout designed to allow them to be raised in due course, if necessary. Ongoing monitoring and maintenance will deal with risks such as settlement of or damage to embankments The versatility to allow the defences to be raised in the future, for whatever reason, would ensure that the scheme will provide a 1 in 200 year standard for at least the next 50 years.
