| Abstract: | The paper analyzes the change law of the bed roughness of river reach f from Baishatan to Sanchahekou or Neijiang river under different degree of middle and small floods, obtains the main channel roughness change law of the HaerNao. The roughness becomes smaller while the water level rising. when the water level is above 130.4 m and the floods over the bank, the roughness will increase. |
