Radiotracer and sealed source techniques for sediment management. Report of the consultants meeting

Abstract

Radioisotopes as tracers and sealed sources have been a useful and often irreplaceable tool for sediment transport studies. Gamma scattering and transmission gauges are used for sediment monitoring. Computational fluid dynamics (CFD) modelling is now an essential tool for the management of the natural systems and are increasingly used to study the fate and behaviour of particulates and contaminants. Radiotracer techniques are often employed to validate CFD models to enhance confidence in the predictive value of the models. Experimental tracing and numerical modelling are complementary methods of studying complex systems. During the last few decades, many radiotracer studies for the investigation of sediment transport in natural systems have been conducted worldwide, and various techniques for tracing and monitoring sediment have been developed by individual tracer groups. However, the developed techniques and methods for sediment tracing have not been compiled yet as a technical document, which is essential for the preservation of the knowledge and transfer of the technology to developing countries. Standard procedures or guidelines for the tracer experiments, which are vital for the reliability of the experiments and the acceptance of end-users, have not been established by the international tracer community either.

Radiotracer techniques are often employed to validate CFD models to enhance confidence in the predictive value of the models. Experimental tracing and numerical modelling are complementary methods of studying complex systems. During the last few decades, many radiotracer studies for the investigation of sediment transport in natural systems have been conducted worldwide, and various techniques for tracing and monitoring sediment have been developed by individual tracer groups. However, the developed techniques and methods for sediment tracing have not been compiled yet as a technical document, which is essential for the preservation of the knowledge and transfer of the technology to developing countries. Standard procedures or guidelines for the tracer experiments, which are vital for the reliability of the experiments and the acceptance of end-users, have not been established by the international tracer community either. The use of radiotracers in sediment transport studies demands the additional attention of the community to further develop these techniques and to ensure their transfer to developing countries. The Consultants' Meeting on 'Radiotracer and sealed source techniques for sediment management' was convened at the headquarters of the International Atomic Energy Agency (IAEA) in Vienna, Austria, from 21 to 25 April 2008. Experts from Argentina, Brazil, France, India, Republic of Korea and United Kingdom have been invited to discuss the current status of the tracer and nucleonic gauge technologies as applied for sediment transport investigations and to evaluate issues related to the further development of this activity. The main objective of the consultants meeting was to review the status of and trends in radiotracer and sealed source techniques as applied to the investigation of sediment transport in natural systems. Developed and developing countries have built up a know-how in the application, design and implementation of radioactive particle tracers particular for sediment transport with support from the IAEA over the past 30 years. Continuing support of personnel and organizations in the Member States is required in order to maintain and possibly re-build activity, capacity and use in order not to lose. Currently models cannot provide accurate sediment transport predictions given the difficult processes involved in complex situations. Sediment tracers provide a unique capability and understanding for sediment transport and sediment management which cannot be obtained any other way, whether conventional monitoring or physical and numerical models because they integrate all the hydrodynamic actions in time and space. Since the environmental, economic and social benefits from the application of tracer technology are enormous, it is recommended that this activity should be promoted further to take full advantages of the modern technologies. Under the scenario of climate change, these techniques can provide tools to handle sustainable developments of environmental resources, particularly in coastal areas and water management. A CRP on Development of radiotracer technology and its integration with hydrodynamic models for sediment management in coastal systems was proposed for the IAEA approval.}
