About unmanaged realignment

Unmanaged Realignment is the process by which existing sea walls or embankments are breached naturally by tidal waters, often following storm events. 

In such cases there may be little or no preparation (e.g. no construction of a new defences and no deliberate opening of the seawalls).  However, this does not mean that the risk of flooding was not recognised in advance or those decisions were made to allow this natural site evolution to occur. 

Once created in this 'non-deliberate' manner, the site is then left to return to coastal habitat.  A decision to not intervene is likely to be taken based on the flood risk to hinterland communities and the role that the site plays in the coastal ecosystem.
