3.2.1. Surface Irrigation

One of the most common and oldest methods of irrigation is surface irrigation. This method uses the force of gravity to distribute the water, which then seeps into the soil. It’s also known as flood irrigation because it simply allows water to flow into an area. Surface irrigation can be divided into furrow, border strip or basin irrigation. This method is not as efficient as other options because there is a tendency to use too much water in order to saturate the land.
