Managed realignment

Engineering activities

Activity and function

Potential hydromorphological change

Mitigation measures

Regulated tidal exchange

To allow the retention of existing defences whilst allowing tidal incursion to landward area

Change in tidal prism

Change to hydrodynamics (TraC)

Manage and Restore the Intertidal Zone

Bank or breach realignment

To create a gap in an existing defence for the exchange of tidal water to provide space for water, or resolve erosive pressures on defences

Change in tidal prism

Loss of area of intertidal zone

Change to hydrodynamics (TraC)

Manage and Restore the Intertidal Zone
