Optimal deployment of sediment resources in river basins

The interrelationships between basin sediment resources and social economy, ecological environment, water resources are investigated and the principles for sediment deployment are analyzed. It is pointed out that the main tasks of deployment include the analysis on the demand of social and economic development, analysis on eco-environmental quality, management of sediment resources, implementation and method for deployment as well as the analysis on the benefit of deployment and how to realize the joint deployment of water resources and sediment. The concept of basin sediment carrying capacity is suggested based on the equilibrium between water resources and water being transported, and the equilibrium between eco-environment and water resources. The basic equation sets for optimization of basin sediment resources deployment are established. The optimization can be expressed by solving the multiple objective functions under the conditions of given limitations. The theoretical framework of optimal sediment deployment include the study on law of sediment transport, maximization of economic benefit, promotion of social environmental benefit and relevant policies.
