Cross shore structures

Engineering activities

Activity and function

Potential hydromorphological Change

Mitigation Measures

Groynes

To interrupt the alongshore transport of sediment and help retain sediment on the foreshore

Change in the structure and condition of the intertidal zone

Change in sedimentary regime (TraC)

Change to hydrodynamics (TraC)

Manage and Restore the Intertidal Zone

Good Practice Sediment Management

Hard points

To influence the realignment of the coastline towards a more sustainable form (by altering hydrodynamic and associated sedimentary regime)

Change in sedimentary regime (TraC)

Change to hydrodynamics (TraC)

Manage and Restore the Intertidal Zone

Good Practice Sediment Management

Piers, harbour arms

To provide protection to a delineated area for access to the marine environment irrespective of hydrodynamic conditions

Change in the structure and condition of the intertidal zone

Change in sedimentary regime (TraC)

Change to hydrodynamics (TraC)

Manage and Restore the Intertidal Zone
