| Summary, etc. | An integrated computer model (RIW AP) was developed to calculate the crop water requirements and canal delivery schedules of irrigation systems. The model is interactive, user friendly, and can be operated on real time basis. Model RIW AP can be applied at the end of each irrigation week to find the irrigation requirements and canal delivery schedules for the following week. Climatic, field, crop, and canal data were input interactively through the program INPUT. Weekly water requirements of paddy was estimated by program PADDY using water balance approach. Water requirement of sugarcane and the week of irrigation was found out by program SUGAR based on soil moisture profiles simulated by solving the governing equation for one dimensional flow using finite difference approach. Water uptake by sugarcane has been computed using Feddes sink function. Weekly rainfall was predicted using Leaky law based on historical rainfall record. Programs SRA and EXRAIN were used for predicting the rainfall. Canal flow rates and delivery schedules were computed by the program SCHED. Program RIW AP combined all these programs appropriately and provided the user interface through menus. The developed model RIW AP was tested in the Tha Maka sub project of the Mae Klong irrigation project in Thailand and the results were compared with the existing model W ASAM and actual practice. Amount of irrigation estimated by RIW AP was lower compared to W ASAM. However the actual irrigation applied was found to be lower than those suggested by both RIW AP and W ASAM. Continuous irrigation, as proposed by W ASAM, practiced in the project has resulted in low flow rates and higher losses and thereby in low efficiency. To rectify this, higher flow rates and rotational delivery schedules were proposed by this study. In addition some canals were found to be under designed, if optimum water has to be applied to the corresponding command area throughout the season. |
