Study of irrigation performance index in Saba irrigation area

Journal of Infrastructure Planning and Engineering (JIPE), 2022
Saba Irrigation Area is located in Gerokgak and Seririt District, Buleleng regency, Bali. The assessment of the irrigation performance index is required to maintain the value of irrigation asset function and condition. Some problems occur in the irrigation area from the standard area of 1548 ha, but the productive land is around 889 ha or about 57% of ...

Irrigation performance under alternative field designs in a spate irrigation system with large field dimensions

, 2020
The sustainability of spate-irrigated agriculture in a semi-arid climate depends on efficient use of irrigation water. Thus, efficient capture and storage of soil moisture in the field are crucial for sustained productivity.

Performance of Irrigated Agriculture in the Panam Irrigation Project of Gujarat

Agricultural Research, 2020
There is large mismatch between the irrigation water supply and demand in the Panam irrigation project in Gujarat, India, arising from high spatiotemporal variation in occurrence and distribution of rainfall. Gross irrigation requirement of crops in the command area was estimated to quantify the gaps.

Irrigation Performance: An Evaluation

Journal of the Irrigation and Drainage Division, 1979
The efficiency and distribution of water of an irrigation can be described by the measurement of as few as four independent quantities, provided three assumptions are made: (1)All water delivered to a field and not infiltrated or not collected as runoff for reuse is a loss, and the nature of that loss is not important; (2)the requirement at the time of

Irrigation Performance Assessment in Crimea, Ukraine

International Journal of Water Resources Development, 2006
After the collapse of the Soviet Union the performance of irrigated agriculture decreased drastically in Ukraine, due to problems related to the transition from a centrally planned economy to a market economy. Before formulating recommendations on required actions to modify this problematic situation, insight is needed about (i) whether irrigated ...
