Description: Technical Memorandum
From the Preface: A suitable means of marking and identifying individual grains of beach and estuarine sediments in order to follow their exact movement over a selected time increment has long been sought as a valuable tool in understanding littoral processes and the mechanics of sediment movement by waves and currents. With the recent advances in the radioactive labelling of selected particles, the use of radioactive tracers in shore studies has become a distinct possibility. Considerable work in this field has been done by coastal engineers in Europe (as, for example, the experiments on the Thames River using radioactive scandium glass), but relatively little progress has been made so far in this country on this adaptation of the radioactive tracers technique. This report presents the results of recent work done in the Netherlands. It initially discusses sediment movement by waves and currents, and ordinary methods of measuring this movement; it then discusses methods of introducing and using radioactive tracers. The characteristics of the various isotopes are tabulated with a view to their possible use for various types of coastal experimentation. A pilot experiment to measure sediment transport in a hydraulic model by use of irradiated glass pearls is discussed, and it was concluded that sediment transport can be safely measured both qualitatively and quantitatively by this method by ordinary field survey parties. Manufacture and initial placement of the radioactive material must be supervised by experts, but after this only minor safety control is sufficient.
