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 [...]
To evaluate the furrow irrigation system, rate of advance and recession are observed as in case of border strips. However, the ring infiltrometer data will not be applicable to furrows as in case of furrows, only a part of the soil is exposed to the water. The intake rate in the furrows is determined either by the ponding method or [...]
In this article we will discuss about:- 1. Hydraulics of Borders 2. Unit Stream Approach 3. Evaluation of Border Irrigation. Hydraulics of Borders: The hydraulics of border irrigation consists in developing equations relating the flow phenomena. The fluid flow phenomenon of surface irrigation is a case of unsteady non-uniform and spatially varied open channel flow over a porous bed. It [...]
