[en] Full text: The CM was attended by five consultants from China, New Zealand, the United Kingdom, the USA and France was held at the Vienna International Centre. The objectives of this CM were: 1) To review recent advances and future trends in the use of isotopic, nuclear and related conventional techniques to investigate the production, mobilization, transfer and storage of sediment, to establish watershed sediment budgets and to assess sediment-associated pollution problems at the watershed scale. 2) To identify key research needs in developing and improved understanding of watershed sediment budgets and the source identification, transport and storage of sediment and sediment-associated contamination problems by exploiting the use of nuclear techniques. 3) To plan a Coordinated Research Project that would develop tools (knowledge, techniques, approaches/strategies and protocols) for watershed- scale assessment of soil loss/sediment transport to support the development of improved land management and sediment control strategies. The outcome of this CM was the development of a proposal for a CRP entitled: 'Tracking sediment sources and transfers at the watershed scale using isotopic and nuclear techniques, to ensure sustainable agriculture and environmental protection'.
