Irrigation engineering deals with the planning, designing, and maintaining

irrigation systems for the transport and distribution of water to residential and

agricultural sites.

What are the works involved in irrigation engineering?

The work involved in irrigation engineering may oversee the installation of

pipelines and sprinklers, or be involved in directing water from dams, canals, and

rivers.

The work is done in the field to evaluate terrain, soil, and climactic characteristics

to optimise the use of water for lawns and agricultural crops.

Computers are often employed for modelling techniques to plan blueprints of

irrigation systems, and present these to subcontractors or installation technicians.

What is irrigation engineering?

Irrigation engineering addresses ongoing issues of drought and national water

shortages, focus on developing irrigation systems that prioritise water

sustainability.

Irrigation engineering may be involved in researching water recycling methods and

developing new ways of minimising water seepage and evaporation loss.

What are the uses of irrigation engineering?

Irrigation engineering is often employed in agricultural industries such as cotton,

dairy, and horticulture.

Other works involve the residential and business sectors in the construction of

irrigation systems for homeowners and office buildings.

What are the main objectives of irrigation engineering?

Understanding, designing and developing the most effective irrigation system for

the area to be watered.

Enhancing current topographical features to improve both soil and water

conservation in the area to be irrigated. This is often done by reading maps and

studying aerial photographs, especially for agricultural irrigation systems.

Educating consumers about the various types of irrigation systems including

sprinklers and drip systems and how they will impact water and soil conservation.

India is an agricultural and populous country. About 70 percent of people

depend on agriculture. In order to grow food-crops and agricultural products in

large quantities to feed the growing millions, intensive farming and rotation of

crops are essential. Extensive irrigation is, therefore, necessary for more

production.

The rainfall of our country is dependent on the monsoons. Rainfall controls

our agriculture. But the agriculture of our country is said to be, "the gambling

of the monsoon" as the monsoon rainfalls are uncertain, irregular and uneven

or unequal.

Irrigation engineering is very much important for better development of the

agricultural sector in terms of crop yield, protection from famine, generation of

water supply, better improvement of cash crops etc.
