@dsear and @joewheaton,
I have developed up the tool that uses the floodplain partition to transfer DoD data to the segmented centre line. This was a raster developed in previous work which has a 2m resolution and the cell values represent m3 change.
Here is the DoD from 2011, reds are erosion, blues are deposition and the grey is zero change.
The tool will carry out zonal stats at the floodplain partition level, correct for NULL values and transfer over to the segment the SUM of erosion values (< 0), SUM of deposition (> 0) and compute gross change (Sum of Erosion * -1) + (Sum of Deposition)
Centre line showing gross change.
