Study Notes
Surface Irrigation Process
- The primary purpose of the physical system in surface irrigation is to distribute water over the land to achieve a desired moisture distribution.
Factors Influencing Advance Rate
- The advance rate of water in surface irrigation is largely influenced by the factor of infiltration.
Key Terms and Phases
- Basin Irrigation: The cumulative time since the initiation of irrigation until the inflow is terminated is known as basin irrigation.
- Cutback: The practice of using a high unit discharge during the advance phase and a reduced one during the wetting or ponding phase to control runoff is known as cutback.
Definition of Surface Irrigation
- Surface irrigation refers to the application of water to the soil surface, where it flows over the land and infiltrates into the soil.
