| Abstract: | The fluctuating uplift forces acting on various size of rock blocks at the bottom of the scour pool are measured in the Three Gorges spillway model. The experimental results agree with the theoretical analysis, which provides scientific basis for mechanism of rock scour and design of concrete slabs in a plunge pool. |

| Keywords: | scour pool model of transient flow fluctuating uplift |
