| dc.description.abstract | The major function of irrigation is to supplement water to growing crops with the quantities which cannot be sufficed by the nature, in order to ensure food productions. The conventional water use plan for irrigation operation and management is made based on the stance of "supply" which takes into account the amount of irrigation water diverted from water sources, then flowing through various levels of canals, and reaching farms for the needs of normal growth of crops. This concept implies that the supply side dominates the "demand" side; and its adjustment to the fluctuating water sources is much dependent on the operator's experience, in case there are not established irrigation operation criteria to cope with changing water sources. Under such a circumstance, when the system operator are absent, and few appropriate personal are available to replace them, then the conventional irrigation operation mechanism is often discontinued. With an aim to solve the aforesaid implication in irrigation operation, in this paper are examined and probed the following issues, on the basis of irrigation at right time and with proper quantities: 1. Relation between diverted amounts of water (Qs) and farm requirements (Qd); 2. Distinctions between conveyance loss (S) and factor of loss (K); 3. Influence of diverted amount of water (Qs) to irrigation efficiencies (E); 4. Relation between irrigation efficiencies (E) and irrigation time (t). Water use plans for reasonable irrigation operation and then studied and discussed, from the view point of irrigation management. | |
