Abstract

Taking the middle and upper reaches of the Sanzhuang River in Donggang District, Rizhao City as the research object, three different special working conditions were proposed, and a one-two-dimensional coupled hydrodynamic model was used to simulate the flood evolution process along the river channel, and the flood simulation and inundation analysis under different flood recurrence periods were completed. The flood evolution process under different working conditions is simulated, and the flood inundation information under the three working conditions is obtained, and the flood inundation analysis is carried out. The results show that the simultaneous laying of bridges and barrages in the river channel has the greatest impact on the flood flow of the river, and the higher the number, the more likely it is to cause the flooding of the river, and the greater the flood overflow range of the same evolution. When flooding of the same frequency, the inundation caused by the bridge is greater than the inundation caused by the barrage.
