We're looking for photographs that show water level during the flood that retain the time-stamp (photographs taken by smartphones and most digital cameras generally include information on the time, date, and sometimes place, that the photo was taken.
We’re concentrating on the area either side of Aboyne Bridge BUT in the future we’d like to include studies elsewhere along the Dee during Storm Frank – from Banchory to Braemar for the Dee and its side streams. So we’d welcome any time-stamped photography of before the flood, DURING the flood, and after the flood. Our aim is to crowd source multiple photos of the same location taken at different times.

Crowd-Sourcing the Hydrograph
A hydrograph is a plot of water-level through time, for a single location. In general the data for these charts come from gauges in permanent monitoring stations mounted along rivers. But every photograph of a river carries information on water-level and can be used to reconstruct changing levels if we know the time (hours, minutes) that the photograph was taken – and can match the water-level on the photo to known objects (trees, buildings, telegraph poles, road surfaces etc.). We will calibrate the elevation of objects using a high-resolution survey.
We are also interested in photographs of the build-up of wood and debris around the bridge during and after the flood, and the patterns of sediment deposited.
In the diagram above a cross section shows the normal river level and how we might determine the river height at different times. If we source enough photography we can build up a 3D hydrograph upstream and downstream from the bridge.
The annotated photograph below shows the water level on the Birse side of the Aboyne Bridge at 10.44am – it is visible on the road by the motorbike. The other lines are annotated water levels on the road at different times 10.56am and 11.36am (as established from other photographs). The blue dot marks the height of the water on the fence at 13.06.
