Sediment: Water Clarity, Suspended & Deposited Sediment
Switch tabs below to look at different variables.
Water clarity
Water clarity (m) results for the period 2015/16 to 2019/20 benchmarked against National Objectives Framework (NOF) guidelines. Modelled grades (coloured lines on the map) are shown for River Environment Classification reaches order three and above. See methods for details on modelling and benchmarks.
Drag and scroll on the map to move and zoom in on areas of interest, hover on the site circles and river lines to see more information, click the top right checkboxes to show/hide layers (double clicking will bring that layer to the front), and use the selection box on the top left of the map ( ) to subset table data.
Click on table rows to highlight those sites on the map above and click on table headers or the arrows next to them ( ↓↑ ) to sort that column.
Deposited fine sediment
Deposited fine sediment (% cover) results for the period 2015/16 to 2019/20 benchmarked against National Objectives Framework (NOF) guidelines. Modelled grades (coloured lines on the map) are shown for River Environment Classification reaches order three and above. See methods for details on modelling and benchmarks.

Suspended sediment concentration
Suspended sediment concentration (g/m3) results for the period 2017/18 to 2019/20.
Drag and scroll on the map to move and zoom in on areas of interest, hover on the site circles and river lines to see more information, click the top right checkbox to show/hide rivers order three and above on the map, and use the selection box on the top left of the map ( ) to subset table data.
Click on table rows to highlight those sites on the map above and click on table headers or the arrows next to them ( ↓↑ ) to sort that column. n refers to the number of samples and units are g/m3 unless otherwise noted.
Total suspended solids
Total suspended solids (g/m3) results for the period 2017/18 to 2019/20.
Drag and scroll on the map to move and zoom in on areas of interest, hover on the site circles and river lines to see more information, click the top right checkbox to show/hide rivers order three and above on the map, and use the selection box on the top left of the map ( ) to subset table data.
