一、前言研究泥沙运动有各种不同方法:有地质学方法,水文学方法,也有地球物理和地球化学等方法。本文着重介绍用放射性示踪沙的方法。最早用示踪沙方法研究泥沙运动,是1954年在英国的泰晤士河进行的。后来在法国、日本、荷兰、葡萄牙以及美国等二十多个国家,也相继开展了这方面的研究工作。在我国,上海航道局设计研究所与南科所合作,也在长江口地区用放射性示踪沙进行过现场试
I. Preface There are different ways to study sediment movement: there are methods of geology, hydrology, and methods of geophysics and geochemistry. This article focuses on the use of radioactive tracer sand method. The earliest study of sediment movement by tracer sand method was carried out on the Thames in England in 1954. Later in France, Japan, the Netherlands, Portugal and the United States more than 20 countries, have also conducted research in this area. In China, the Shanghai Waterway Bureau Design Institute and the Southern Branch by cooperation, but also in the Yangtze Estuary using radioactive tracer sand field test
