Abstract

Despite geomorphic processes being increasingly recognized as a vital component of river management projects, evidence suggests that they may not be adequately captured in common river assessment procedures. We reviewed 91 river assessment procedures from around the world to evaluate their effectiveness in capturing geomorphic processes relevant for river management goals. Our objectives were to summarize which common geomorphic indicators are measured and how in different types of river assessments categorized based on their main focus: geomorphic, physical habitat, mixed geomorphic and habitat, and hydromorphology. Our analysis identified differences in the types of geomorphic indicators included and measurement methodologies between the types of assessment procedures. Some geomorphic processes, such as sediment transport, are nearly completely absent from all assessments, despite their importance for geomorphic processes. The variability among assessment procedures suggests that a single procedure is unlikely to capture all geomorphic components required to support every river management programs. Here, we discuss how the strengths and limitations of different assessment types can be used to guide decisions around how to select assessments and geomorphic indicators to support management project goals. A companion paper expands the discussion of how to plan effective river assessment procedures to support unique management goals.

河流评估程序中的地貌测量 1:当前做法全球概览
尽管人们日益认识到地貌过程是河流管理项目的重要组成部分,但有证据表明,常见的河流评估程序可能没有充分反映地貌过程。我们审查了世界各地的 91 项河流评估程序,以评估它们在捕捉与河流管理目标相关的地貌过程方面的有效性。我们的目标是总结不同类型的河流评估根据其主要侧重点(地貌、物理栖息地、混合地貌和栖息地以及水文形态)测量了哪些常见地貌指标以及如何测量。我们的分析发现,不同类型的评估程序所包含的地貌指标类型和测量方法存在差异。有些地貌过程,如沉积物运移,尽管对地貌过程非常重要,但在所有评估中几乎完全没有出现。不同评估程序之间的差异表明,单一程序不可能涵盖支持每种河流管理计划所需的所有地貌要素。在此,我们将讨论如何利用不同评估类型的优势和局限性来指导如何选择评估和地貌指标,以支持管理项目目标。另一篇论文将进一步讨论如何规划有效的河流评估程序,以支持独特的管理目标。

期刊介绍: JAWRA seeks to be the preeminent scholarly publication on multidisciplinary water resources issues. JAWRA papers present ideas derived from multiple disciplines woven together to give insight into a critical water issue, or are based primarily upon a single discipline with important applications to other disciplines. Papers often cover the topics of recent AWRA conferences such as riparian ecology, geographic information systems, adaptive management, and water policy. JAWRA authors present work within their disciplinary fields to a broader audience. Our Associate Editors and reviewers reflect this diversity to ensure a knowledgeable and fair review of a broad range of topics. We particularly encourage submissions of papers which impart a ''take home message'' our readers can use.
