Sedimentary dynamics measuring method for tracing e.g. sand, involves introducing activable artificial tracer in aquatic medium, sampling sample of medium, and dosing content, in tracer, in sample

摘要

The method involves introducing an activable artificial tracer (2) in an aquatic medium, and sampling a sample (4) of the aquatic medium. The content in the tracer is dosed in the sample by a method selected among an analysis through gamma spectrometry of the activity induced through neutron activation or photo activation and physico-chemical or physical method. The concentration in the tracer of the analyzed sample is deduced from the dosing. A sediment transfer parameter is deduced from a set of the sampled samples based on time and space. Independent claims are also included for the following: (1) a method for tracing sediments (2) a method for controlling constructions in aquatic medium, port installations, navigation channels, redevelopment of seaside or sea embankment.
