摘要: 渭河下游河段洪澇災害易發,分析渭河下游防洪保護區的洪水風險,有助于完善渭河洪水防御體系,開展防汛應急工作和洪水風險管理。以渭河下游防洪保護區為研究對象,基于MIKE軟件建立一維、二維耦合模型,采用實測洪水數據驗證模型的合理性,進而模擬分析該保護區各潰口在相應類型和頻率洪水條件下的洪水演進過程、淹沒范圍和淹沒損失等。研究結果表明,渭河下游河勢復雜多變,不同位置潰口潰決后的風險差別較大,同頻率洪水下,最大淹沒面積、淹沒片區最大總損失、最大避險轉移等發生在不同的片區。

Abstract: The Lower Weihe River is prone to flood disasters. Flood risk analysis of this area can provide important information for floodcontrol system construction, flood control command and flood risk management. This paper established a onedimensional and twodimensional coupled hydrodynamic model, verified the correctness of the model with measured data and then applied it to the flood control protected area of the Lower Weihe River. Then it analyzed the evolution process, inundation areas of the floods under different operation conditions and flood recurrence periods. The results show that under the same conditions, the maximum inundated area, the greatest loss and the maximum number of residents transfer are occurred in different regions.
Key words: flood risk; flood routing; MIKE software; Lower Weihe River
