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.
