本章回顾了各种水流路由算法，这些算法模拟了水在景观中的分布和流动。九个这样的算法和实验，已经进行了评估，在过去的15年中，他们的表现的显着特点进行了讨论。从那里，我们考虑了三组持久的挑战：（1）土壤和水之间的尺度和反馈的作用，以及在表征两者的属性时考虑这些问题的必要性;（2）在许多景观中需要动态流量路由算法和相关指标;（3）在土壤水分性质的表征中，将空间和时间作为连续变量处理的可能性。本章最后指出了当前的最新技术水平和我们可能从这里走向何方
This chapter reviews the various flow routing algorithms that simulate the distribution and flow of water across landscapes. The distinguishing characteristics of nine such algorithms and the experiments that have been conducted to evaluate their performance over the past 15 years are discussed. From there, we consider three sets of enduring challenges: (1) the role of scale and feedback between soil and water, and the need to consider these issues when characterizing the properties of both; (2) the need for dynamic flow routing algorithms and related indices in many landscapes; and (3) some of the as yet unrealized opportunities for treating space and time as continuous variables in the representation of soil water properties. The chapter concludes by noting the current state-of-the-art and where we might go from here
