这里描述的物理河流特征数据集提供了空间上一致的信息，以支持英国国家网格上1 km × 1 km分辨率的水文和洪水建模。物理河流特征数据集提供网格化数据集（流出排水方向、集水区、河岸河流宽度和河岸河流深度）和逗号分隔的NRFA（国家河流流量档案）测量站位置表。这些数据集来自一系列来源：流出排水方向，集水区和河岸宽度来自现有的高分辨率数据集，而河岸深度更难来源，而是来自稀疏的历史测量。新的网格化数据集为英国国家网格（BNG）上的每个英国陆地单元提供了派生值。逗号分隔的NRFA测量站位置表提供了1，499个河流流量测量站在1 km分辨率网格上的最合适位置，以及上游集水区1 km × 1 km网格划分的近似误差。本文解释了如何估计这些变量的英国范围的1 km网格，它们的格式以及如何使用它们。这些数据来自环境信息数据中心。
The physical river characteristics datasets described here provide spatially consistent information to support hydrological and inundation modelling at a 1 km × 1 km resolution across the United Kingdom, on the British National Grid. The datasets of physical river characteristics provide gridded datasets (outflow drainage directions, catchment areas, widths of bankfull rivers and depths of bankfull rivers) and a comma‐separated table of NRFA (National River Flow Archive) gauging station locations. These datasets are derived from a range of sources: outflow drainage directions, catchment area and bankfull river widths are derived from existing higher resolution datasets, whereas bankfull river depths were harder to source and instead are derived from sparse historical measurements. The new gridded datasets provide a derived value for each UK land cell on the British National Grid (BNG). The comma‐separated NRFA gauging station locations table provides the most appropriate locations of 1,499 river flow gauging stations on the 1 km resolution grids, together with the approximate error in the 1 km × 1 km gridded delineation of the upstream catchment area. This article explains how UK‐wide 1‐km grids of these variables were estimated, their format and how to use them. The data are available from the Environmental Information Data Centre (EIDC).
