在本文中，我们简要概述了地貌瞬时单位过程线（GIUH）理论，并分析了其成功路径，同时不掩盖其局限性。 GIUH 的历史分为三个主要部分。第一个基于 Rodríguez‐Iturbe 和 Valdés 的里程碑式工作（Water Resources Research 1979；15(6): 1409–1420）和 Gupta 等人。 （Water Resources Research 1980; 16(5): 855–862），该论文认识到用“行程时间”处理排水可以为瞬时单位过程线（IUH）理论提供丰富的解释。我们展示了这是如何实现的，做出了哪些假设，哪些假设可以放宽，哪些已经过时并被丢弃。第二部分重点介绍基于宽度函数的 IUH（WFIUH）方法及其在评估网络拓扑和几何与水动力学的相互作用方面取得的成就。描述了 WFIH 方法的局限性，并提出了解决这些问题的方法。最后，引入并阐明了一种通过“行程时间”估算水预算的新正式方法，该方法源于对水预算方程和一些假设的适当使用。版权所有 © 2015 约翰·威利父子有限公司
In this paper we present a brief overview of geomorphological instantaneous unit hydrograph (GIUH) theories and analyze their successful path without hiding their limitations. The history of the GIUH is subdivided into three major sections. The first is based on the milestone works of Rodríguez‐Iturbe and Valdés (Water Resources Research 1979; 15(6): 1409–1420) and Gupta et al. (Water Resources Research 1980; 16(5): 855–862), which recognized that a treatment of water discharges with ‘travel times’ could provide a rich interpretation of the theory of the instantaneous unit hydrograph (IUH). We show how this was possible, what assumptions were made, which of these assumptions can be relaxed, and which have become obsolete and been discarded. The second section focuses on the width‐function‐based IUH (WFIUH) approach and its achievements in assessing the interplay of the topology and geometry of the network with water dynamics. The limitations of the WFIUH approach are described, and a way to work around them is suggested. Finally, a new formal approach to estimating the water budget by ‘travel times’, which derives from a suitable use of the water budget equation and some hypotheses, has been introduced and disentangled.
