Irrigation is the bringing of water to dry land to grow crops. Irrigation channels, drip irrigation, irrigate the fields.
It is the oldest large-scale engineering there is, and the first states grew up to manage it. Drip irrigation delivers water to the root rather than the field and uses a fraction of the water, which matters as aquifers fall. In medicine, irrigation is washing a wound.
