Beach management

Engineering activities

Activity and function

Potential hydromorphological change

Mitigation measures

Re-nourishment and recharge

To introduce as a one-off (or repeat application) a volume of fresh sediment to the beach to restore intertidal volume, width and level

Change in the structure and condition of the intertidal zone

Loss of area of intertidal zone

Change in sedimentary regime (TraC)

Manage and Restore the Intertidal Zone

Good Practice Sediment Management

Recycling

To move sediment from an area of deposition to an area of depletion to restore volume, width and level at a particular section

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

Reprofiling or regrading

To redistribute the sediment on a beach from the lower and mid beach to the upper beach to build a protective crest level and beach width or a more stable angle of repose

Change in the structure and condition of the intertidal zone

Change in tidal prism

Change in sedimentary regime (TraC)

Manage and Restore the Intertidal Zone

Bypassing

To restore the longshore movement of sediment around an artificial structure to maintain the sedimentary regime
