On the basis of analyzing theorem of incipient motion for stone blocks on a slope under water flow action, from studying a single stone block on a slope and using the limit equilibrium condition of a special block′s incipient motion under water flow action, a formula for calculating average diameter of special blocks is derived. Then using this formula, the two shapes and their corresponding dimensions of concrete special blocks, one shape and its corresponding dimensions of a reinforced gabion and their engineering layout forms, are designed. Combining with engineering practice, the construction mechanism and effect of concrete special blocks and reinforced gabions are described briefly. The comparisons with classical bank protection form and with different materials are carried out. The suitable conditions of using concrete special blocks and reinforced gabions for bank protection and erosion control, are also described. Their application to reinforcing caving banks which are under rapid flow action, is suggested with major efforts. [
