Polder: A polder is a piece of low-lying land that has been reclaimed from a body of water and protected by dikes or embankments.
Coastal Engineering: Coastal engineering involves designing and constructing structures along coastlines to protect against erosion and flooding while also reclaiming land.
Dredging: Dredging is the process of removing sediment or debris from bodies of water using machinery. It can be used as part of land reclamation projects to clear areas for construction.
