Underground pipeline systems (also known as buried pipelines) are being increasingly used for conveying irrigation water on the farm. The main advantages of these systems are – saving of land, elimination of seepage losses, and relatively little maintenance need. Under most conditions a properly installed pipeline system will function well for several years. However, they need a higher initial cost [...]
In this article we will discuss about:- 1. Surface Irrigation Methods 2. Calculating Depth of Irrigation 3. Mathematical Models 4. Implements. Surface Irrigation Methods: These can be broadly classified as follows: 1. Wild flooding or uncontrolled flooding. 2. Controlled flooding, further classified as: (i) Border method, (ii) Check basin method or flat-bed method, and (iii) Basin method. 3. Furrow irrigation, [...]
Design of Surface Irrigation Systems: In every irrigation system a particular size of steam is available to irrigate the land with a particular topography and soil characteristics. These should be matched in such a way that the required amount of water is applied all over the field as uniformly as possible and at the same time no soil losses occur [...]
