Identification of corridors of river recovery for NSW Lower North Coast catchments

By connecting corridors of river recovery, resilience can be built into river systems to mitigate against future floods and droughts driven by anthropogenic disturbance or climate extremes. This database can be used to systematically analyse where corridors of geomorphic river recovery could be created via conservation or rehabilitation. Analysis is undertaken in ArcGIS using the recovery potential layer of the Open Access NSW River Styles database that is available from DPIE (www.dpie.nsw.gov.au). The River Styles database was accessed in January 2021. The database and associated workflow identifies reach and loci connections based on different combinations of recovery potential classes. Reach connections are defined as an upstream to downstream section of river that is connected end-to-end, and loci connections are defined as isolated sections of river from which recovery can be seeded and extended into adjacent reaches. This map for all freshwater stream length of the NSW Lower North Coast catchments, shows the spatial distribution of thirteen connections based on combinations and sequences of conservation, strategic and high recovery potential targets. Other connections of interest to river practitioners can be identified and >80 different user-defined scenarios run using a workflow available at protocols.io.\r\n\r\nAttribution to: Macquarie University, D Agnew and K Fryirs (2022) Corridors of river recovery database and workflow.

通过连通河流恢复廊道（corridors of river recovery），可为河流系统构建韧性，以缓解人为扰动或极端气候驱动的未来洪涝与干旱灾害。

本数据集可用于系统分析：通过保护或修复手段，可在何处构建地貌河流恢复（geomorphic river recovery）廊道。分析工作基于新南威尔士州（New South Wales, NSW）公开获取的《河流类型（River Styles）》数据集的恢复潜力图层，在ArcGIS中开展，该数据集可从新南威尔士州规划与产业部（DPIE，www.dpie.nsw.gov.au）获取。本研究于2021年1月调取该河流类型数据集。

本数据集及其配套工作流基于不同恢复潜力等级的组合，识别河段连接与位点连接：河段连接指首尾相连的上下游河流区段；位点连接指可作为恢复起点、并可延伸至相邻河段的孤立河流区段。

针对新南威尔士州下北海岸流域的全部淡水溪流长度，本数据集的可视化地图展示了基于保护、战略性与高恢复潜力目标的组合及序列所得到的13类连通廊道的空间分布。河流管理从业者可借助protocols.io平台公开的工作流，识别其他所需的连通廊道，并运行超过80种用户自定义场景。
