Detailed explanation-1: -In a dug well, water is collected from water bearing strata. Tube wells can tap water from the deeper strata. From these wells, water is lifted by pumps for irrigation. (II) Canals: This is usually an elaborate and extensive irrigation system.
Detailed explanation-2: -The earth is formed of different layers of materials like sand, clay, gravel, limestone, etc. The layers like those of sand, gravel, etc actually allow the water to pass through them and they contain quantities of water in them. These are called aquifers or water-bearing strata.
Detailed explanation-3: -A dug well consists of an excavated hole in the ground, from which drinking-water may be accessed from a groundwater aquifer (which is typically shallow).
Detailed explanation-4: -well is a hole drilled into the ground to access water contained in an aquifer. A pipe and a pump are used to pull water out of the ground, and a screen filters out unwanted particles that could clog the pipe.
