The coastal protection at labrador park is an example of hard engineering which is building seawalls. The seawalls is built along the coast. It is usually made of concrete which absorbs energy from the waves and protects the coast from strong waves.
Limitations:
But the seawall is not very long lasting. The waves which break against the seawall would be redirected to the base of the seawall which results in a strong backwash. Eventually, the base of the seawall would weaken and collapse. Thus, it is not a long lasting method and it is also very expensive to built the seawalls.
