Lagoons play a significant role when it comes to shaping a coastline, however it isn’t always the lagoon that does so. When lagoons are created, a barrier island is created to separate the lagoon from the ocean. The barrier island helps to prevent the full force of waves hitting the coast which can effect the coastlines’ erosional process.
Coastal lagoons are known to cause coastal inundation, which is when the coastal lands become flooded by ocean waters. Broad areas of marshy wetlands around lagoons cause floods with salt water to occur during high tides.
As seen on the excursion, there is a lagoon at Dee Why
