Flood defences in Kent underwent emergency repairs after snow and storms damaged a sea wall.
The Environment Agency said it carried out work on the wall in Deal after a member of the public noticed a section had been washed away.
The defences are regularly shored up with shingle, but the work was brought forward to repair the damage.
The agency said it is already planning new flood defences between Deal Castle and Sandwich Bay Estate.
Paul Marshall, Incident Response Team Leader, said: "We acted quickly to shore up the defences and would like to thank the person who contacted us."
The agency is working with Dover District Council on a plan to improve defences, which include building a wave wall between the Royal Hotel and Deal Castle.
Residents will be consulted on the scheme later in the year.
