Identification of corridors of river recovery for NSW Hunter 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 Hunter 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，可为河流系统构建韧性，以缓解由人为扰动或极端气候引发的未来洪涝与干旱灾害。本数据集可用于系统性分析：通过保护或修复手段，可在何处构建地貌型河流恢复廊道。该分析基于新南威尔士州规划与产业部（DPIE）公开可获取的《新南威尔士州河流类型数据库》（NSW River Styles Database）的恢复潜力图层，在ArcGIS中完成。该数据库于2021年1月获取。本数据集及配套工作流基于不同的恢复潜力等级组合，识别河段连接与源点连接：河段连接指首尾相连的上下游河流段；源点连接指可作为恢复起点并延伸至相邻河段的孤立河流区段。针对新南威尔士州亨特流域全部淡水溪流的此份专题地图，展示了基于保护类、战略类与高恢复潜力目标的组合及序列所得到的13类连接的空间分布。河流管理从业者关注的其他连接可通过protocols.io平台公开的工作流进行识别，并模拟运行超过80种用户自定义场景。
