摘要

台灣四面環海雨量豐沛水資源豐富，社會大眾對水土資源有效利用及各項水利設施之建成關注程度日益提高。而河川、湖泊為水土資源與水利設施之根本，因此長期且確實掌握河川動態實為國人研究之首要目標。而掌握河川動態之因子首推河川斷面積之估算。
一直以來河川斷面量測必須耗費大量人力、金錢、時間，且考慮到洪水過後河川底床變動，資料時效性有限。憑藉透地雷達經濟、快速有效率、非接觸水體等優點，本研究發展透地雷達法量測河川斷面，以期達到節省經費並增加施測頻率之效果。
河川斷面積為一重要水文因子，不論是流量推估、各項水利工程、各類型模式演算，其都為必要參數。研究中以量測北勢溪流域河川為主，建立透地雷達量測流程，已期達到快速量測之效果。經由各種處理功能率定河川底床波形以增加資料判釋準確性，與傳統鉛錘法比較後結果顯示河川斷面積差異約在10%以內，證實此法能夠運用於實際量測。

River section has been measured to be a lot of manpower, money, time, and taking into account changes in the floods after the river bed, limited time-sensitive information. GPR by virtue of the economic, fast and efficient, non-contact water, etc., the Research GPR measurement of river sections in order to achieve savings and to increase the effect of testing frequency.
Basal area of river hydrology is an important factor, whether the flow estimate, the water conservancy project, the type of model calculations, the parameters for the necessary. Study to measure the Beishi rivers mainly penetrating radar to establish measurement processes, has been to achieve the effect of rapid measurement. Filter through the various processing functions will be to increase the river bed waveform data interpretation accuracy, with the traditional method plumb the river after the results showed that differences in basal area within about 10% confirmed that this method can be applied to actual measurements.
