Answer 1

Required Answer:

☑ Irrigation is the process of supplying water to the land at regular intervals by means of canals and other artificial methods, to enhance agricultural growth and maintain the landscape during the periods of less average rainfall.

☑ A reservoir is most commonly an enlarged natural or artificial lake created using a dam to store fresh water. 

Answer 2

Answer:

Irrigation is the agricultural process of applying controlled amounts of water to land to assist in the production of crops, as well as to grow landscape plants and lawns, where it may be known as watering. Agriculture that does not use irrigation but instead relies only on direct rainfall is referred to as rain-fed. Irrigation has been a central feature of agriculture for over 5,000 years and has been developed independently by many cultures across the globe.

A reservoir is most commonly an enlarged natural or artificial lake created using a dam to store fresh water.

Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees.
