| 摘 要： | 1 INTRODUCTION The Lower Yellow River is a suspended river channel bed much higher than the adjacent ground behind the dikes, well known all over the world. The floods flow east into the sea under the constraints of dikes. The safety of the dikes or embankments mainly relies on the protection provided by the river training works that have been constructed and maintained for several thousand years. There are three types of river training works and they are spurs, guide banks, and reve…

| Abstract: | A formula for the computations of local scour depth at the head of spurs is derived according to the equilibrium principle of incipient motion of sediment particle. The proposed formula is verified with laboratory data and field measurements. In the derivation of this formula, two different scour resistance forces, the cohesive force and the gravitational force, are considered, and the integrated coefficient is calibrated using data from the Lower Yellow River. |
