| Summary: | 博士 === 國立臺灣大學 === 農業工程學研究所 === 89 === The wet-dry seasons are distinct in southern part of Taiwan. The mean annual rainfall in this area is 2,406 mm, however, only about 250 mm (10.4%) appears in the dry season from November to April. Although the reservoir capacity reaches 979.6×106 m3, its effectiveness is reduced due to sedimentation problems. As a result, flooding in wet seasons and drought in dry seasons often occur in this area.
In this project, the Kang-Shan irrigation area of Kaohsiung Irrigation Association was selected. The background and water resource development process were first studied, and the soil and water utilization problems were discussed, then a series of agricultural water conservation plans were proposed in accordance with A-Kong-Tien revision project, as well as status changes. The feasibility of these plans was evaluated in an attempt to alleviate the flooding and drought problems. Finally, the Lu-Chu Scientific Park was taken as an example to show that, without new water sources, the agricultural water could assist industrial water by means of the measures as proposed in this study.
Based on preliminary results, the projected water requirement of 2.6×104 tons could be supplied by return water, which was intercepted from upstream irrigation, diverted to farm ponds, stored, and stilled before use. Nevertheless, detailed procedures and cost estimation should be further studied.
