Exclusive homes located on Sydney's Collaroy Beach are in danger of collapsing after high tides and huge waves caused severe erosion for a second night. The waves swash moves materials upwards and its backwash pulls the materials down. Watch on. It is associated with high-pressure weather where there is a low wave energy. The beach was closed on Wednesday due to powerful surf conditions. Assessing cross-shore and alongshore variation in beach morphology due to wave climate: Storms to decades.

A second spring tide hit the beach on Monday night, eroding the sand by another 5m and causing additional damage to the houses. He said more research would be needed to determine the extent the seawall played in Tuesdays erosion event, but that north-easterly waves were certainly a key driver in drawing sand off the beach. The reason fiberglass replacement windows are stronger and more durable is due to its makeup. They are predicted to be more likely and more intense. For each of these beaches Coastal Zone Management Plans have been prepared that aim to preserve and protect these beaches as well as ensure development takes into account current and future hazards from coastal storms.
