摘要:
为了进一步改善流域洪水空间变化与水库调节影响的模拟,应用分布式水文模型HEC-HMS,在考虑大型水库调节模拟的基础上,对东南沿海晋江流域的暴雨次洪进行多站点率定模拟分析。选取1972~1979年晋江流域15场特大暴雨洪水,以洪峰误差、洪量误差、峰现时间、效率系数为评价指标,进行10场参数率定和5场模型验证。安溪、洪濑、石砻三个水文站在模型率定期的平均效率系数分别为0.892、0.895、0.921,验证期的平均效率系数分别为0.866、0.822、0.853,模拟效果较好,精度较高。结果表明:利用多站点模拟的方法,可以从流域尺度上更客观地率定模型参数,改善模型的模拟效果;初损率与起涨流量相关性显著,为模型洪水预报应用时初损参数的确定提供重要依据;山美水库的径流调节对洪濑站和石砻站的模拟结果具有显著影响。
Abstract:
Extreme storm runoffs often cause flood hazards. The convective rainstorms and typhoon storms occur frequently in summer, and the loss caused by flood is often tremendous in the south-east coastal of China. In this study, a hydrological model(HEC-HMS)was applied to Jinjiang watershed in this region. In order to improve the flood simulation in spatial variation of river basin, three hydrological stations were used for calibration and validation in simulation. The regulation of a large reservoir was also simulated. Ten rainstorm flood events occurring from 1972 to 1975 were used to calibrate the model using a trial-and-error approach, and five rainstorm events occurring from 1975 to 1979 were used to validate the model. The simulation results were evaluated with the errors of flood peak discharge, flood volume and time of peak discharge, and efficiency coefficient. The average efficiency coefficients for calibration in three hydrological stations of Anxi, Honglai and Shilong were 0.892, 0.895 and 0.921, respectively, while 0.866, 0.822 and 0.853 in validation period. It shows that the calibration and validation with three stations result in more realistic parameter values and improve the simulation efficiency. The correlation between initial loss and initial discharge makes the model more applicable for flood forecasting. The regulation of Shanmei Reservoir has a great affect to the simulation of Honglai and Shilong.
