| 英文摘要 | Transporting sediment is a natural function of the river. To maintain the normal evolution of the river certain amount of water flow is required, which is called the instream flow requirements for transporting sediment (IFRTS). We defined the permitting flow velocity by the conception of IFRTS, and also put forward the ecological hydraulic radius model (EHRM) to estimate IFRTS. The calculating process of EHRM is explained by the example of Daofu Hydrological Station on Xianshui branch of Yalong River in the west line first-stage construction of South-North Water Transfer Project. The result shows that the IFRTS occupied 29.7%-59.5% of annual mean discharge in flood season, the average of IFRTS was about 100.2 m(3)/s during 1966-1987, it is close to the IFRTS 90 m(3)/s calculated by IFRTS conception. Hence, it is feasible to use EHRM to calculate IFRTS. |
