近年来示踪技术作为研究水动力和泥沙冲淤规律的工具得到越来越广泛的应用。示踪技术比传统的水文观测方法方便、准确。传统研究方法往往只能进行定点或走航采样监测,而示踪技术则能准确判定某一区域泥沙或水流的具体运动过程和最终运动结果,甚至给出定量的结论,从而为数学模型参数的确定提供有效的依据。Pujol使用3H监测西班牙Ebro河的横向扩散速率[1],Albert在Ebo河用同样的方法研究水
In recent years, tracer technology has been more and more widely used as a tool to study the law of water erosion and sedimentation. Tracer technology than traditional hydrological methods is convenient and accurate. The traditional research method can only carry out fixed-point or go-around sampling and monitoring, while tracer technology can accurately determine the specific movement process and final movement result of sediment or water flow in a certain area, and even give quantitative conclusions, so that the mathematical model parameters To provide an effective basis for the determination. Pujol used 3H to monitor the lateral diffusion rate of the Ebro River in Spain [1]. Albert studied the water in the same way with the Ebo River
