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 the environmental impact that results from faulty management of irrigation water. The environmental impacts are: 1. Rise in Water Table 2. Water-Logging 3. Soil Salinisation 4. Lowering of Water Table. Environmental Impact # 1. Rise in Water Table: In many canal command areas, faulty irrigation water management practices have resulted in rising of [...]
