中文摘要 | 利用全球衛星差分定位及三音束測深系統,於 1993 年及 1994 年霧社水庫之計 畫中已成功地使用,並且在測點之空間分佈上能提供一有效的收集方法。在這計畫中,我們 進一步使用 60 音束的測深系統,在日月潭、霧社水庫及德基水庫內,每年一次提供比以往 更高解析之公尺級水深圖。本計畫之主要目的在於不同之水庫地形條件下,包括不同之庫底 坡及深度值,評估測深系統之使用效率。因此本文中所提供之水庫容水量僅供電廠參考。然 而,根據不同時段的水深測值差,水庫內之淤積狀態在本文中將予以討論;結果顯示,水庫 之地形、地勢變化深深影響水庫之淤積行為模式。 |
英文摘要 | In 1993 and 1994, the project with a system combining the DGPS positioning and tri-beams echo sounding technique to survey the bathymetry in Wushie Reservoir was done successfully. It provides an efficient method in collecting a good coverage of bathymetrical data in the field. In this project, a 60-beam sounding system was used to provide higher resoluable meterscale bathymetrical maps of Sun Moon Lake, Wushie and Techi Reservoirs under the yearly basis than before. The purpose of the project is to evaluate the efficiency of the system conducting the bathymetry in different kinds of reservoirs in terms of their bottom slope and the depths of water. The amount of water in each reservoir given in this paper is only for reference. However, siltation behavior in each reservoir is also discussed and the results indicate that there is mutual relation between the distribution of the deposition and the shape as well as the topography of the reservoir. |
