Coastal infrastructure refers to the structures and facilities built along coastlines to support human activities and protect against natural forces. This includes seawalls, docks, harbors, and beachfront promenades. These constructions help manage the impact of waves, tides, and storm surges, ensuring safety and accessibility for communities. Additionally, coastal infrastructure plays a vital role in economic activities such as fishing, shipping, and tourism. Properly designed infrastructure can enhance resilience against climate change effects, like rising sea levels and increased storm intensity. Effective planning and maintenance are essential for the longevity and functionality of these coastal systems.
