碩士 === 國立臺灣大學 === 農業工程學系 === 84 === The amount of conveyance loss of irrigation system is very high ratio to total agricultural irrigation water in Taiwan for several seasons. The conveyance distance is long within the amount of irrigation water, many structures have damaged or beside their design age for apply to conveyance irrigation water. Only based on the results of input and output, as "Black Box Analysis" method is adopted to analyze former lost to satisfy the irrigation requirement for farmer in past study. Therefore, Most people misunderstand that there will have a linear relationship between the irrigation area and irrigation water demands. The purpose of this study is more detail to study the previous questions. The influence factors of conveyance loss in irrigation channel had analyzed and to construct serial model dependent on the influence factor of conveyance loss, and to estimate conveyance loss amount, made the definition of irrigation water requirement will be more clearly. The field results of irrigation use of water through each irrigation association under normal state (wet growing seasons) in Taiwan can abtam the rational conveyance loss of each irrigation association from the model. And again, To calculate irrigation water requirement of irrigation system from this model based on the different improvement analysis can be obtained the maximum available improvement amount, in order to improve water resource efficient apply potential and the management of irrigation in Taiwan.
