中文摘要	In this paper, some schemes for managing sediment of the TGP reservoir are presented. To reduce deposition and to increase the flood storing capacity, Lin and the author suggested to shortly draw down the pool level to 135m, i.e., 10m below the prescribed flood control level (FCL), in the period slightly ahead of the arrival of a flood. The transport capacity in this period could then be much enhanced so as to keep more sediment suspended and to scour the earlier depositions. Through this way, the capacity of TGP reservoir could be increased, backwater and flood stages along the reservoir could be obviously lowered, and, navigation conditions in the fluctuating backwater region could also be improved. Financial and social benefits from such reduction of deposition could be quite considerable. The study is based on an 1D numerical model, which has been verified with long-term field data of sediment transport by unsteady flow in the Lower Yellow River as well as with some results of scale model testing. In view of the importance of the TGP, however, further investigations, including comparison of measured data from TGP reservoir at 135m since 2003 with that from physical models and mathematical models, are planned.
