Geospatial Data:- Watershed delineation based on hydrology toolbox in ArcGIS (ESRI, version 10.3)- Mapped disturbances based on aerial photographs from 1952 and 1970 (for Ice Creek East, Ice Creek West and Eastern Gully only) and satellite imagery from 2011 (GeoEye-1) and 2015 (WorldView2). Note that no disturbances were found in Slump D creek.Hydrology Data:- Manual flow measurements with the Flo-Mate 2000 Flow Meter different streams on Herschel Island- Runoff data in Ice Creek East - continuous measurements- Runoff data in Ice Creek West - continuous measurementsHydrochemistry Data:- hydrochemistry data of 2016 including pH, conductivity, turbidity, stable water isotopes, solutes, POC and DOCMore details on the methods can be found in the accompanying manuscript.
