The pipe-shaped geotextile, long bags filled with earth, is a kind of soft structures for anti-scour. This paper sums up the design and construction of the structure and discusses its effects on anti-scour in practical engineerings for bank protection on the. lower Yellow River. The author thinks how to connect all bags togather as an entire structure and how to improve the technique for filling them with earth are the main problems in their application.

This paper presents the trial application of sawdust (with the specific mass gravity of 1. 2 t / m3) and the natural sand (with the specific mass gravity of 2.65t / m3) to fully simulate the bed load with a wide gradation in the course of the hydraulic model studies for the local scour downstream from the hydroelectric project and the slope stability of the cofferdams. In the design of the model materials it was stressed to simulate the coarse grain (d75) which could affect the stability of anti-scouring. At the same time, according to the different key parts simulated by the test, the corresponding time scales or scour and deposit to release the model flow had been determined and to get the topography of scour and deposit with needed extent. By verification or the measured data on the flood-discharging and the river bed closure works for the Shuikou project of Minjiang River, the trend and elevation of the topography variation due to scour and deposit, the grain sizes and amount of the dumping ma terials, as well as the hydraulic parameters for the open channel and the closure mouth, measured on the model, were all identical with those measured on the prototype.
