Which is the oldest system of irrigation?
Surface irrigation, also known as gravity irrigation, is the oldest form of irrigation and has been in use for thousands of years. In surface (furrow, flood, or level basin) irrigation systems, water moves across the surface of agricultural lands, in order to wet it and infiltrate into the soil.
What ancient civilizations used irrigation?
As better techniques developed, societies in Egypt and China built irrigation canals, dams, dikes, and water storage facilities. Ancient Rome built structures called aqueducts to carry water from snowmelt in the Alps to cities and towns in the valleys below. This water was used for drinking, washing, and irrigation.
How did ancient irrigation systems work?
Underground Canals – Underground canals are thought to be the most complex and ingenious of the ancient irrigation systems. Dating back to 300 BCE in Sri Lanka, this method tapped into natural springs and underground water sources, allowing water to flow as needed and water crops in the fields.
Who invented ancient irrigation?
The Sumerians dug canals in what are considered the first ever works of engineering. It is thought that canals could be used for up to 1,000 years before being replaced. Terrace irrigation is an ancient technique that was used all over the world, including in China and India, but it was used especially in the Americas.
What was irrigation in ancient India?

What is terrace irrigation?
Each step is irrigated by water transported down the mountainside from springs, rivers, or reservoirs, using a complex network of canals, sluices, and pipes. The terraces allow the hillside to be cultivated with a minimum of soil erosion; they serve to keep irrigation water on the fields. Photograph 1.
What are the traditional method of irrigation?

What are different types of terraces?
There are two basic types of terraces—storage terraces and gradient terraces. Storage terraces collect water and store it until it can infiltrate into the ground or release through a stable outlet. Gradient terraces are designed as a channel to slow runoff water and carry it to a stable outlet.
What is used for irrigation in old farming method?
Traditional Irrigation Methods
- Moat. Also called the pulley system, it involves pulling up water from a well or other such source to irrigate the land.
- Chain pump. A chain pump consists of two large wheels connected by a chain.
- Dhekli. It is a process of drawing water from a well or such similar source.
- Rahat.
What was the irrigation system of Cholas?
The irrigation system during Chola rule was much improved. A variety of methods were applied for it. Many wells were dug; huge tanks were constructed to collect water. The kings themselves took an interest in organizing labor and resources and extensive planning was done.

What is a terraced irrigation system?
Perhaps the most scenic and exotic these irrigation works are the terraced mountainsides (see photograph 1 ). Terraces are the product of massive highly organized human efforts. They turn mountain slopes into oversized “stairsteps” of narrow fields, each held up by a retaining wall.
What is the importance of rice terraces in the Philippines?
The terraces allow the hillside to be cultivated with a minimum of soil erosion; they serve to keep irrigation water on the fields. Photograph 1. The rice terraces in northern Luzon, Phillipines, are some of the most spectacular in the world.
Were the terraces at Machu Picchu ever irrigated?
The fields created by the ancient agricultural terraces at Machu Picchu totalled only a few acres. The terraces are formed by stone retaining walls, contain thick topsoil, and are well drained. Field investigations conducted over several years by Kenneth Wright, P.E., and his colleagues found no evidence that the terraces were ever irrigated.
How do they irrigate in the Andes?
