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 [...]
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 [...]
