Seawalls
Seawalls are employed as a mechanism to minimize the damage of high tides that come to the shore. High tides have to be dealt with due to their destructive force and violent acceleration of coastal erosion. The seawalls also benefit visitors who prefer to stay on the shore with plenty of space for them without the disturbance of any wild incoming tides.
At Lady Robinson, the sea wall is built to prevent the high tides from eroding further inland where the local shops and restaurants are. Although the sea wall has the intention to stop erosion, it has actually increased the speed of erosion by letting the high tide wash away more sand at a quicker pace.

Groynes
Groynes are one of the most common engineering solutions to beaches that are experiencing erosion. Groynes prevent longshore drift as they block a majority of the sand from being swept down the beach. Because the sand gets piled up along the groynes, the sand is wider directly on ether side and thinner in between two groynes. There have been a total of ten groynes built along Lady Robinson Beach, and these groynes along with sea walls and breakwaters all aid in slowing down the process of erosion due to longshore drift.
Cooks River Ecology Grant
The Cooks River Foreshore Improvement Program approved a grant for Rockdale, Kogarah, Canterbury and Marrickville Councils to undertake an ecological study of the Cooks River in relation to water quality. The project’s objective is to establish a cost-effective, ecological monitoring program that will provide guidelines for the management of tidal vegetation and inform capital works projects along the riverbanks.
Beach Nourishment
Beach nourishment is needed at Lady Robinson Beach due to the sea wall quickly eroding away the sand. Erosion is a reccurring problem and beach nourishment is another management option. It would help the beach from being completely washed away and preserve it for much longer.
Beach nourishment involves the dumping of sand or gravel to widen the beach and to protect the shoreline from damage caused during large storms. After a combination of high tides, big waves and waves reflecting off the sea wall, Brighton was left with barely any sand. To return the beach to it's original shape, beach nourishment was used. This took place at Lady Robinson Beach in 2005.
