| 英文摘要 | Check dam systems are extensively utilized on the Loess Plateau. However, the development of the check dam system is restrained due to the failure hazard. To investigate the failure process of the check dam system and the corresponding effect, a hydrodynamic simulation was conducted in this study based on the failure of a typical check dam system, which occurred on 15 July 2012. The simulation was regarded as satisfactory based on verification with observed data of the peak discharge at the outlet of the catchment (NSE = 0.61, R-2 = 0.83), breaches of damaged check dams (relative error < 20%) and maximum water depths in the front of 2 check dams (relative error of - 13.4% and + 4%). The simulation results indicated that the series failure in the tributary ditch did not cause the stack of peak discharges, and the peak flood discharge at the outlet of the catchment in this failure increased 20% compared to the status without dam-break and decreased 87% compared to the status without check dam. |
