摘要

    摘要
  • 摘要: 借助DEM提取汇水区是分布式水文模型计算和面源污染计算的前提条件。在平坦地区直接使用DEM提取出的水系、汇水区边界与现实情况差异很大。针对现有汇水区提取方法存在的问题,在RIDEM模型的基础上提出了一种平原河网地区汇水区划分的方法,该方法通过将道路、建筑物、水系、沟渠、坑塘等影响径流途径的地物要素融合进DEM,达到细化DEM的目的,从而使由细化的DEM生成的河网与实际河网能够精确拟合,优于原始DEM和RIDEM的提取效果,提高了水系提取和汇水区划分的精度,建筑物对径流的阻碍作用也能够得到体现。实证研究表明,该方法是一种方便、快捷、高效的处理方法。
    Abstract: The extraction of hydrological information from Digital Elevation Models(DEM) is an initial step in the application of spatially distributed hydrological models.Although,many automated methods have been proposed to extract the drainage structure from DEMs,the realistic river network and watershed boundary may not always be derived from conventional DEM processing methods.As a result,enhanced (or corrective) approaches have been proposed to improve the performance of existing single flow direction (D8) algorithms.However,those corrective measures may not always work over flat regions where the great uncertainty exists in DEM.Ambiguities in flow direction and parallel flow paths may arise if the surrounding cells have the same elevation as the central cell.In this paper,to downscale the DEM and extract drainage structures and watershed boundaries with improved accuracy a new method is proposed based on the Rural Infrastructure Digital Elevation Model is able to incorporate ancillary data and take into consideration of anthropogenic land cover features(i.e.roads and streams,buildings,some ponds and pipe systems) that influence drainage patterns.The method is applied to a watershed in the Shanghai drainage basin.The watershed can be characterized as a flat area undergoing a rapid urbanization process.The delineated maps and extracted stream networks are compared to those of using traditional methods.The result shows that the proposed method is able to produce more realistic results.The method is effective and easy to implement.
