利用HEC模型分析下垫面变化对洪水影响
nalysis how flood responds to the change of underlying surface with the HEC model
近些年，由于气候变化和人类活动的双重作用改变了流域下垫面的水文特性，探讨研究下垫面变化的水文响应过程具有重要的理论和现实意义。通过HEC模型对伊河东湾流域采用历史反演法的模拟结果表明，东湾流域在1964-2000年近40年来，下垫面的调蓄作用有所增大，次洪径流相对于往年的来说偏小了大约35.11%，次洪洪峰偏小了约5.15%。90年代之前和90年代之后下垫面条件下在较大洪水上差别不大，在较小洪水上的差别稍大。
In recent years, climate change and human activities have change the hydrological characteristics of underlying surface. In this condition, it is important to study how the flood responds to the changes of land which is also of important theoretical and practical significance. The final simulation results by applying the HEC model show that the food volume and peak flow value decreased by 35.11% and 5.15% respectively from 1964 to 2000 in Dong Wan basin. The effect of land-cover between current cover and past cover on hydrology was small for large storm and big for small storm events.
