资源简介：
This layer shows the relative contribution of eight sources of phosphate in each WFD waterbody as predicted by the SAGIS model in 2024. The data was originally provided by the Environment Agency to The Rivers Trust as point data with multiple points per WFD waterbody. These point values have been averaged to give a single value for each WFD waterbody. Any catchments without a WFD waterbody IDs have been excluded from the analysis.
