摘要

Abstract >The accuracy and efficiency of the simulations in distributed hydrological models must depend on the proper estimation of flow directions and paths. Numerous studies have been carried out to delineate the drainage patterns based on gridded digital elevation models (DEMs). The triangulated irregular network (TIN) has been increasingly applied in hydrological applications due to the advantages of high storage efficiency and multi‐scale adaptive performance. Much of the previous literature focuses mainly on filling the depressions on gridded DEMs rather than treating the special cases in TIN structures, which has hampered its applications to hydrological models. This study proposes a triangulation‐based solution for the removal of flat areas and pits to enhance the simulation of flow routing on triangulated facet networks. Based on the drainage‐constrained TIN generated from only a gridded DEM by the compound point extraction (CPE) method, the inconsistent situations including flat triangles, V‐shape flat edges and sink nodes are respectively identified and rectified. The optimization algorithm is an iterative process of TIN reconstruction, in which the flat areas are generalized into their center points and the pits are rectified by embedding break lines. To verify the proposed algorithm and investigate the potential for flow routing, flow paths of steepest descent are derived by the vector‐based tracking algorithm based on the optimized TIN. A case study of TIN optimization and flow path tracking was performed on a real‐world DEM. The outcomes indicate that the proposed approach can effectively solve the problem of inconsistencies without a significant loss in accuracy of the terrain model. </abstract> </span> <span

>分布式水文模型中模拟的准确性和效率必须取决于流动方向和路径的正确估计。已经进行了许多研究以基于网格数字高度模型（DEM）来描绘排水模式。由于高存储效率和多尺寸自适应性能，三角形的不规则网络（TIN）越来越多地应用于水文应用中。以前的大部分文献主要侧重于填补网格DEM上的萧条，而不是在锡结构中处理特殊情况，这阻碍了其对水文模型的应用。本研究提出了一种基于三角剖分的解决方案，用于去除平坦区域和凹坑，以增强三角形小平面网络上的流量路由的模拟。基于由化合物提取（CPE）方法仅由网格萃取（CPE）方法产生的排水限制锡，分别识别并整流包括平三角形，V形平边缘和沉积节点的不一致情况。优化算法是锡锡重建的迭代过程，其中平坦区域被广泛地进入其中心点，并且通过嵌入断线来整流凹坑。为了验证所提出的算法并研究流量路由的可能性，最陡下降的流动路径由基于型号的基于矢量的跟踪算法导出。对真实世界的DEM进行了对锡优化和流路跟踪的案例研究。结果表明，该方法可以有效解决不一致的问题，没有地形模型的准确性大幅损失。</
