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. |
