英文摘要	For enhancement of the efficiency of sediment transport under constraints of water resources utilization, we proposed a four-layer framework based on the concept of Water Use Efficiency for Sediment Transport (WUEST). The major state parameters at different layers of the system include the incoming water and sediment from the upstream (IWS), the characteristics of river channel (CRC), the sediment carrying capacity of river flow (SCF), and the control capability of hydraulic engineering works (CEW). According to the measured data from 1950 to 1997, the WUEST in four typical reaches of the Lower Yellow River was investigated under different conditions (or IWS), i.e. the natural condition (NC), the engineering-controlled condition (EC), the complex condition (CC) and the abnormal conditions (AC). Comparison was made between different operation schemes in connection with sediment carrying capacity, e.g. the scheme of using the water in wet season to flush the total sediment load in the whole year. These schemes could decrease water demand for sediment transport and enhance the water use efficiency. The schemes could be implemented by the proper operation of hydraulic engineering works.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000226799100038&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Water Resources; CPCI-S(ISTP); 0
