Frequency of Commonwealth environmental water - wetland and floodplain inundation

Extent of surface water (outside of river channels) thought to contain Commonwealth environmental water either alone or in partnership with other water holders. Mapped as the annual frequency of inundation. Raster data set derived from Landsat and Sentinel-2 observations of water extent checked annually with water managers. Excludes natural flooding and inundation by other sources of environmental water where there was not a component of Commonwealth environmental water.\r\n\r\nCompiled by the Flow-MER Basin scale project.\r\n\r\n2014-2019 data based on information from the Long Term Intervention Monitoring (LTIM) project.\r\n\r\nThe CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings.

We respect their continuing connection to culture and Country, and we thank them for their knowledge and science and the values reflected in these data.\r\n\r\n###Citation\r\n\r\nCEWH (2024) Frequency of Commonwealth environmental water - wetland and floodplain inundation 2014-2021.

本数据集针对河道外的地表水范围，即单独包含或与其他水权持有者合作时涉及联邦环境水（Commonwealth Environmental Water）的区域，以年度淹没频率进行制图。该栅格数据集基于Landsat与Sentinel-2的水体范围观测数据制作，并每年由水管理方核验，不含自然洪水，以及未包含联邦环境水组分的其他来源环境水所造成的淹没区域。

本数据集由Flow-MER流域尺度项目编制。

2014至2019年的数据基于长期干预监测（Long Term Intervention Monitoring, LTIM）项目的相关信息生成。

联邦环境水持有者（Commonwealth Environmental Water Holder, CEWH）旗下的Flow-MER项目，旨在评估联邦环境水对《2012年流域计划》（Basin Plan）环境目标的贡献，并协助CEWH验证环境治理成效、对所持水资源开展适应性管理。如需了解该数据集的方法与报告详情，请访问：https://www.dcceew.gov.au/water/cewo/monitoring/mer-program。

###致谢

联邦环境水持有者与Flow-MER项目参与方谨此确认：第一民族（First Nations peoples）是墨累-达令盆地的土地、水道与空域的传统所有者与守护者。我们尊重其与文化及故土的持续联结，并感谢其贡献的知识与科学智慧，以及本数据集所体现的价值理念。
