Answer:
Irrigation.
Explanation:
Basically, when you dig a ditch in the ground to bring water from a river to another place, this process is referred to as irrigation. This ultimately implies that, this ditch are dug as a storage tank which would be used to store water gotten from river or other artificial sources.
In the area of agriculture, water gotten through irrigation are typically used to nourish and enrich crops that are grown in dry and dusty areas. Also, when there's a decrease in the amount of rainfall such as during summer, farmers tend to use irrigation as a source of water supply for their agricultural crops at needed intervals.
