| Abstract | The study was conducted in the Phitsanulok Irrigation project, Nan river basin, northern part of Thailand. It was primarily concerned with the determination of losses in the conveyance irrigation canals, land preparation requirement and water use efficiencies. Moreover, factors creating losses in the system were indicated and subsequently suggestions
for improvement are given.
The period of study was during the wet season in 1982 and the results revealed that:
1. The average conveyance losses in main, secondary and tertiary canals were 0.023% per km, 1 .1% per km and 6.95% respectively.
2. The land preparation requirement was 194 mm.
3. The land preparation requirement was 194 mm.
The water use efficiencies were 23% and 15% for the monitoring
area M1 (2,400 rai) and M2 (123,526 rai) respectively.
4. The main reason for losses in the system was that the farmers
could receive much more water than necessary at any time they wanted as the tertiary canal head gates could not be completely controlled by the
official people.
5. Water user association improvement, training of RID field staff in operation and maintenance are very urgently required. |
