Water Resources

In arid regions and during dry spells when rainfall is below normal, irrigation is essential for the cultivation of agricultural products, the preservation of landscapes, and the reforestation of disturbed soils. Protection from frost, reduction of weeds in grain fields, and maintenance of loose soil are only few of the additional benefits of irrigation in crop production. Besides watering crops, cooling cattle, and getting rid of dust and sewage, irrigation systems are employed in mining. Many researchers examine irrigation with drainage, the process of channelling water away from a site's surface and beneath its surface.

Irrigation may be done in a number of different ways. In comparison to traditional overhead irrigation methods, micro-irrigation requires significantly less water pressure and water flow. Root-zone drip irrigation is a slow trickle of water.
