The design of open channels consists in designing the cross-section for the given discharge and the velocity of flow. The cross-section should be adequate and the velocity of flow should be permissible for the given material. The different elements of an open channel as shown in Fig. 14.1 are: T = Top width, t = Top width of water surface [...]
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, [...]
