This dataset contains tracer test breakthrough curves, streambed and water surface profile elevation along the thalweg 
and hydraulic conductivity of streambed sediments in ten stream reaches in southest of Sweden. 
Reffere to separate table for the approximate possition of each reach. 

In the folder "Tracer test breakthrough curves" ten text files are found, which represents the resulting breakthrough curves 
from Rhodamine WT (RWT) tracer tests in ten different reaches performed at ten different occasions. 
The file-names includes reach name and date of the injection.
Data description
First column: Time since injection at the upstream measuring point (seconds)
Second column: RWT concentration at the upstream measuring point (µg/L)
Third column: Time since injection at the downstream measuring point (seconds)
Forth column: RWT concentration at the downstream measuring point (µg/L) 
RWT was injected as a slug in the stream water column, a specific distance upstream the initial measuring point. 
Submersible fluorimeters (Cyclops C7, Turner Designs, Inc., U.S.A.) were employed upstream and downstream the investigated 
stream reach to detect the florescence.
Standard calibration curves were prepared in the lab to transform the resistivity (mV) into concentration RWT (µg/L). 
Tracer tests are described more thoroughly in Morén et al. (2021). 

In the folder "Elevation measurements", ten text files are found, which includes stream topography elevation and 
water surface profile elevation along the stream thalweg in ten different reaches.
First column: Distance along the stream thalweg (m)
Second column: Elevation of the streambed (m)
Third column: Elevation of the stream water surface profile (m)
Measurements were performed usin a Leica Sprinter 50 automatic leveling instrument (Leica Geosystems AG, Switzerland), 
at close time to the tracer tests found in this dataset. 
Topography measurements are described more thorouly in Morén et al. (2021). 

In the folder "Hydraulic conductivity measurements" an excell file including hydraulic conductivity data, for four to six cross sections
in eight of the ten reaches investigated in Morén et al. (2021). 
The hydraulic conductivity was measured in each point through a falling head tests using a piezometer, 
and measurements are described more thoroughly in Morén et al. (2021). 
In study reaches R6c and R6d, hydraulic conductivity was not measured as part of this study, but measurement preformed in previous studies 
with the same devise (Kunkel and Radke, 2011; Riml et al., 2013).
