仍然有必要建立集水水文和运输模型,在考虑流速和速度差异的同时,适当地综合优先流的影响。这里提出了一种建模方法,它使用粒子跟踪方法来模拟在一个单一的一致的解决方案中的多个路径的流动和运输。水通量和储存量由颗粒的体积和密度决定,通过用信息标记颗粒来实现运输,这些信息可以在集水区中的颗粒的整个生命周期中进行跟踪。该方法允许通过使用粒子速度分布的优先流的表示,和路径之间的混合可以实现与路径过渡概率。首次提出了一种可转移的三维建模方法,并将其应用于在瑞典Gårdsjön的0.63公顷G1集水区进行的独特的步进同位素实验。该应用程序突出了结合流动和运输的重要性,在水文表示,并在获得满意的代表性的观测路径速度分布和相互作用的重要性。
There is still a need for catchment hydrological and transport models that properly integrate the effects of preferential flows while accounting for differences in velocities and celerities. A modeling methodology is presented here which uses particle tracking methods to simulate both flow and transport in multiple pathways in a single consistent solution. Water fluxes and storages are determined by the volume and density of particles and transport is attained by labeling the particles with information that may be tracked throughout the lifetime of that particle in the catchment. The methodology allows representation of preferential flows through the use of particle velocity distributions, and mixing between pathways can be achieved with pathway transition probabilities. A transferable 3‐D modeling methodology is presented for the first time and applied to a unique step‐shift isotope experiment that was carried out at the 0.63 ha G1 catchment in Gårdsjön, Sweden. This application highlights the importance of combining flow and transport in hydrological representations, and the importance of pathway velocity distributions and interactions in obtaining a satisfactory representation of the observations.
