| Abstract: | This paper studies the distribution laws of flow intensity along the flow direction, the depth direction and the transverse direction based on the flume experiments and theoretical analysis, drafting the contour maps of the flow turbulence intensity and turbulent kinetic energy of the five different types of dam structures and distribution laws. Furthermore, the effect of different dam angles on the flow turbulence intensity and turbulent kinetic energy is also explored. |

| Keywords: | turbulence intensity spur dike flow turbulent kinetic energy dam structure |
