WWNP Riparian Woodland Potential

This dataset has been produced as part of the Mapping Potential for Working with Natural Processes research project (SC150005). The project created a toolbox of mapped data and methods which enable operational staff in England to identify potential locations for Working with Natural Processes (WWNP).

Data has been produced for each intervention covered by the project. The final outputs include the following datasets:
• Floodplain Woodland Planting Potential
• Riparian Woodland Planting Potential
• Wider Catchment Woodland
• Floodplain Reconnection Potential
• Runoff Attenuation Features 3.3% AEP
• Runoff Attenuation Features 1% AEP
• Woodland Constraints

WWNP Riparian Woodland Potential is our best estimate of locations where tree planting may be possible on smaller floodplains close to flow pathways, and effective to attenuate flooding. The dataset is designed to support signposting of riparian areas not already wooded. The dataset is based upon a 50m buffer of available OS Open Data river networks. A set of open access constraints data was used to erase areas which contained existing woodland, watercourses, peat, roads, rail and urban locations.

The information provided is largely based on open data, and is indicative rather than specific. Locations identified may have more recent building or land use than available data indicates. It is important to note that land ownership and change to flood risk have not been considered, and it may be necessary to model the impacts of significant planting.

本数据集作为《与自然过程协同作业潜力映射》研究项目（项目编号：SC150005）的成果之一。该项目构建了一个包含测绘数据和方法的工具箱，旨在帮助英格兰的操作人员识别与自然过程协同作业（WWNP）的潜在地点。项目覆盖的干预措施均产生了相应数据。最终输出包括以下数据集：
• 洪泛平原森林植被种植潜力
• 河岸森林植被种植潜力
• 广泛流域森林
• 洪泛平原重新连接潜力
• 3.3% AEP径流减缓特征
• 1% AEP径流减缓特征
• 森林限制

WWNP河岸森林潜力数据集为我们提供了在靠近水流路径的小型洪泛平原上进行树木种植的可能地点的最佳估计，且对于减缓洪水具有显著效果。该数据集旨在为尚未林化的河岸区域提供指引。数据集基于50米缓冲区的开放OS Open Data河流网络数据。通过一套开放访问的限制数据集，消除了包含现有林地、水道、泥炭、道路、铁路和城市区域的区域。

提供的信息主要基于开放数据，具有指示性而非具体性。识别出的地点可能存在比现有数据所指示更为近期的建筑或土地利用。值得注意的是，未考虑土地所有权和洪水风险的变化，可能需要模拟重大种植的影响。
