Coastal Hazards

• Beach erosion - the offshore movement of sand from the beach during a storm event.
• Shoreline recession - the landward movement of the shoreline over time due to a net loss of sand and sediment.
• Coastal lake or water course entrance stability - the tendency for entrances to close, reopen or form new openings.
• Tidal inundation - the flooding of land by tidal action under average conditions.
• Coastal inundation - Storm-related flooding of coastal lands (storm surge) and wave run-up.
• Coastal cliff or slope instability.

The Newcastle Coastal Zone Management Plan 2018 prescribes the short and medium term actions to manage identified coastal hazards. With two distinct coastal environments, the Newcastle Coastal Zone Management Plan 2018 has two parts: Part A - Stockton and Part B - Coastline South of the Harbour.

You can read more about the work we have completed to manage the beach erosion on Stockton Beach as part of the Stockton Coastal Management Plan and work that is underway on the Southern Beaches Coastal Management Plan.

• Coastal structures (2mins 50secs) such as groynes, breakwalls and seawalls can all impact sand movement.
• Sand nourishment (2mins 38secs) is when you take sand from somewhere else and import it to give you a sandy beach for recreation or to provide more protection during erosion events.
• Sand movement (1min 29 secs) along the NSW Coast is mostly from south to north with both natural and artifical obstacles affecting the movement of sand.
