PROCEDE DE MESURE DE LA DYNAMIQUE SEDIMENTAIRE D'UN SITE, UTILISANT UN TRACEUR ARTIFICIEL ACTIVABLE

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.
