Barrier walls can be placed at the beach if you're not entirely worried about aesthetics. This will stop the waves from hitting the sand and eroding it over time.

This solution involves constructing a line of long structures perpendicular to the coast that reach into the ocean. These are usually made from stone, concrete, steel, or timber, and are designed to keep sand from entering a ship channel. As sand builds up on against the upcurrent side of the jetties, it can be redistributed along the beach to further reduce erosion. However, much like groins, erosion still occurs on the downcurrent side of the jetties

Sandbags are frequently made of burlap or polypropylene and can been seen lining the shores of numerous beaches . The large bags filled with sand actually act like a seawall, contrary to seeming fragile. The advantage of a sandbag instead of a seawall is that a sandbag is much less expensive and easier to maintain.

Seawalls are one particularly effective way to prevent erosion. These are structures that are built along the coastline to stop waves from ever coming into contact with the sand/shore on the opposite side. While seawalls tend to be quite effective at preventing erosion, they are only able to protect the coast that they are installed along.
