| Abstract | Fluctuation of water level in large irrigation system is a common phenomenon. It is
difficult to control the flow and to maintain the water level up to full supply level. Due to
inefficient irrigation system, non adjustable gate operation, obsolete management makes the
system more difficult to supply water as desired by fa1mers. This study focuses the
improvement of operation and management conditions of the Phlaichumphon sub-project as
well as Phitsanulok Irrigation Project, Thailand, using the data from the field site.
A micro computer based software package CanalMan developed by the Utah State
University, USA was applied in order to check the implementation of the model into the
project. The hydraulic parameters of canal system, stream flow and control structures data
were collected from the project site and input into the model for calibration. After simulation
the computed results were compared with the observed data and found satisfactory. To make
the canal system hydraulically stabilize dw-ing the simulation period the lateral outflow were
considered known and it is found that the upper most reach (km 0+075 to km 10+620)
receives excess water to meet the crop water demand. This problem is identified as the most
operational and management problem in Phitsanulok Irrigation Project. The reliability of
discharge measurement and information on the demand of water for each off-take structures
are seen not very dependable.
This study shows that it is difficult to maintain water level at full supply level (FSL)
with manual operation of the gate. In order to minimize such problems use of better hydraulic
models( for example CanalMan) coupled with sound water allocation plan are suggested for
efficient operation and management of the project. |
