【摘要】:為加強洪澤湖周邊滯洪區(qū)的洪水風(fēng)險管理,構(gòu)建了洪澤湖周邊蓄滯洪區(qū)一、二維耦合的洪水演進(jìn)數(shù)學(xué)模型。利用1991、2003、2006、2007年四年歷史洪水資料對模型參數(shù)進(jìn)行率定,驗證了模型的合理性。對洪澤湖50、100、300年一遇三種設(shè)計洪水方案進(jìn)行模擬計算,得到了各類洪水風(fēng)險要素的動態(tài)分布情況,并通過GIS疊加分析,估算了三種方案下的淹沒損失情況,該結(jié)果可為洪澤湖周邊滯洪區(qū)的洪水風(fēng)險管理提供參考依據(jù)。
[Abstract]:In order to strengthen flood risk management in flood detention area around Hongze Lake, a two dimensional coupled flood routing mathematical model was constructed for flood storage and detention area around Hongze Lake. The model parameters are determined by using the data of 1991 / 2003 / 2006 and four years' historical flood in 2007, and the rationality of the model is verified. The dynamic distribution of various flood risk elements is obtained by simulating and calculating three design flood schemes once in 500, 300 years in Hongze Lake, and the flood losses under the three schemes are estimated by GIS superposition analysis. The results can provide reference for flood risk management in flood detention area around Hongze Lake.
