A central pivot irrigation system is a flexible pipe structure that revolves around a pivot point connected to water. Because of their high efficiency and high uniformity, as well as the ability to irrigate uneven terrain and low capital, maintenance, and management costs, center pivot irrigation systems are one of the most widely used sprinkler irrigation systems.
Today there are hundreds of thousands of Valley watering axes around the globe. Electrically powered tractor wheels move the systems through the field. Because the pivot travels further, sprinkler flow rates are higher towards the outer ends of the pivot. The pivot's end is where runoff is most likely to occur. This is the primary design constraint.

In the upcoming paragraphs, we are going to discuss some common types of irrigation systems.
Surface Irrigation:
Surface irrigation is the oldest type of irrigation. It has been used for thousands of years. Surface (or flood) irrigation systems allow water to flow across agricultural lands in order to wet them and infiltrate the soil. You can subdivide surface irrigation into the furrow, border strip, or basin irrigation. Flood irrigation is used when irrigation causes flooding or near flooding on cultivated land. This method was the most popular way to irrigate agricultural land in the past and it is still widely used today.
Sub Irrigation:
Sub-irrigation is a method that has been used in fields with high water tables for years. Sub-irrigation is an artificially raised water table that allows the soil to become moistened below the roots. These systems are often located in permanent grasslands, lowlands, or river valleys and combined with drainage infrastructure. It can control the water table by using a system of pumps stations, canals, and weirs.
