breakwaters
coconut coir logs
groins
seawalls
structures built to create calm waters in a harbor
structures built at the water’s edge or slightly inland
hard structures built perpendicular to the shoreline
biodegradable structures placed along shorelines

Explanation:

• Breakwaters: Their purpose is to create calm waters, often in harbors, so they match "structures built to create calm waters in a harbor".
• Coconut coir logs: These are biodegradable and placed along shorelines for erosion control, so they match "biodegradable structures placed along shorelines".
• Groins: These are hard structures built perpendicular to the shoreline to trap sediment, so they match "hard structures built perpendicular to the shoreline".
• Seawalls: These are built at the water’s edge or slightly inland to protect the shore, so they match "structures built at the water’s edge or slightly inland".

Answer:

• breakwaters: structures built to create calm waters in a harbor
• coconut coir logs: biodegradable structures placed along shorelines
• groins: hard structures built perpendicular to the shoreline
• seawalls: structures built at the water’s edge or slightly inland
