PROPOSAL TO ORGANIZE A WORLD ASSOCIATION FOR SEDIMENT RESEARCH
摘要
Sediment Problems - Matter of Global Concern In the twenty-first century, humanity will be confronted with three major problems, namely rapid increase in population, shortage of natural resources and protection of the environment. There will be a pressing demand for more land and water resources, more raw materials and a decent environment with more balanced ecology for people to live in. Sediment problems in general, including those arising from land erosion, sediment transport in streams and sediment deposition in reservoirs and lakes, will directly affect the rational development of water and soil resources, the control of floods in rivers and the protection of the environment as well as ecology in river basins and hence will impact all the three problems listed above.
