land reclamation
The Yser River flowing through reclaimed farmland in Belgium.
In the context of land reclamation, levees are constructed to confine water and protect low-lying areas from flooding. When excess water accumulates within these protected zones, it must be removed to maintain the land's utility.
Pumps are used to lift this excess water over the levees and discharge it outside the protected area. This process is a critical component of drainage systems in reclaimed lands, such as those found in the lower Mississippi valley or the polder systems of the Netherlands. In areas where the land surface is below the water level of the surrounding body of water, pumping is essential because gravity-based drainage is not possible.12
