Basin irrigation is still used today. It consists of a field enclosed by a raised bank called a dike. The water is allowed to flood the field and the sediment forms a deep layer of mud.

Basin irrigation was the preferred method of distribution in ancient civilizations, specifically ancient Egypt.

Water runs on a sloping ground from one end of the field to another.

This method is often combined with furrows to enhance efficiency.

Furrowed irrigation is created by cutting channels (ditches) within the field by a plow. Water runs down the channels.

Overhead irrigation distributes water from above using a sprinkler system.

Drip irrigation is created by running water into tubes at ground level that have drip emitters (small holes) near the base of the plants.

Delivers water nearly directly to the plants’ roots.

Sub soil irrigation relies on buried water lines that deliver water underground with no surface evaporation.
