Summarization of researches on optimal deployment of water and sediment resources in basin

Reasonable deployment of water and sediment is an important theme that affects river health.It is of significance to understand the relation of flood and sediment catastrophe and the utilization of water and sediment and to develop associated optimal deployment research of water and sediment sources in a basin.In this article,the research advances of this field was analyzed and summarized comprehensively,including optimal deployment research of water and sediment sources in local watersheds such as soil and water conservation planning,associated controlling and management of water and sediment in reservoirs together with transportation and distribution of water and sediment in an irrigated area as well as the optimal deployment theories and mathematical models of water and sediment resources in a whole basin range.The existing problems of water and sediment resources optimal deployment theories,models,schemes and evaluations were discussed.The development tendency in these aspects are suggested.
