基于地貌单位线的汇流模型在陈河流域的构建与应用
|
摘要
针对陈河流域陡涨陡落的洪水过程,采用90 m分辨率的DEM数据提取了陈河流域的水系,进而提取出其瞬时地貌单位线,构建基于地貌单位线的汇流模型;再用该模型对陈河流域2003年到2012年间的13场洪水进行模拟演算,并将计算结果与新安江模型的计算结果相比较。分析结果表明,基于地貌单位线的汇流模型取得了理想的模拟结果。
As the characteristic of rapid rise and recession flood process in Chenhe Catchment,the DEM data with 90 m resolution is used to extract the river systems of Chenhe Catchment, and then, the geomorphologic instantaneous unit hydrograph is extracted. The confluence model based on the geomorphologic instantaneous unit hydrograph is finally constructed. The application of model to flood events between 2003 and 2012 in Chenhe Catchment and the comparison with Xin'anjiang model's simulation results show that the confluence model is effective in Chenhe Catchment.
