Coastal & Marine Engineering
Sea walls, defences and marine structures — heavy civils against a moving enemy.
Coastal engineering is construction where the tide tables set the working day. The corridor civils, earthworks and piling methods are shared with the transport and ports sectors, linked below — but here the sea is not a neighbour, it is the adversary: concrete poured between tides, armour stone placed to the tonne, and every detail designed for the storm that will test it.
The four guides in this sector cover sea walls and revetments — the hard edge between land and water; breakwaters and groynes, structures built in the sea to calm it; beach management and nourishment, defence by the cubic metre of sand; and intertidal working, the logistics of plant, access and concrete in the zone that floods twice a day.
What does Coastal & Marine Engineering cover?
Process guides in Coastal & Marine Engineering
- Sea Walls & Revetments — The hard edge between land and sea — curved wave-return walls, rock armour slopes and stepped revetments — built around the tide and armoured at the toe against scour.
- Breakwaters & Groynes — Structures built out into the sea on purpose — rubble-mound breakwaters armoured in rock or concrete units, and groynes holding the beach where it belongs — placed rock by rock under survey control.
- Beach Management & Nourishment — Fighting erosion with sand instead of stone — dredged fill pumped ashore, profiled to the design beach, then monitored and topped up campaign after campaign.
- Working in the Intertidal Zone — The discipline behind every coastal job — tide tables, working windows, causeways and soft-ground plant, weather limits, and the retreat plan for when the sea comes back.
