Irrigation is the controlled application of water to land for agricultural purposes. It's often used in areas with irregular rainfall or drought. Here are some types of irrigation: Surface irrigation: Also known as furrow or flood irrigation, this is one of the oldest irrigation methods. It involves flowing water down small trenches running through crops. Sprinkler irrigation: Uses a series of pipes to move water from the source to spray heads. Subirrigation: Also known as subsurface irrigation or seepage irrigation, this method delivers water directly to the root area from below the...

Subirrigation: Also known as subsurface irrigation or seepage irrigation, this method delivers water directly to the root area from below the soil surface. Centre pivot irrigation: This self-propelled system uses a central pipe with outlets that rotate around a central pivot point. Furrow irrigation: This method supplies water to crops through shallow, evenly spaced furrows. Dams vs Weirs Dams: Walls, usually curved, that are built behind to form a lake. Dams are often built to provide hydroelectric power. In a dam, water overflows through a spillway. Weirs: Small, impervious barriers built across a river to raise the water level on the upstream side. Weirs are essentially small-scale dams. The water overflows over the weir. Weirs have been used for a long time to control the flow of water in streams, rivers, and other water bodies. Show less
