Experimentelle Rinnenerosionsforschung vs. Modellkonzepte – Quantifizierung der hydraulischen und erosiven Wirksamkeit von Rinnen
Fig. 7: Runoff values after 25m, respectively. 15m for rill experiment 3.
In run A of RE 1 8.41 l of the 72 l inflow reached the measuring point at 15 m this is
equivalent to a runoff rate of 11.68 %. The maximum runoff at the outlet is 0.042 l s -1 that
means 28% of the inflow intensity. The runoff period counts 350 s and it begins 74 s after
stopping inflow. In the second run, 17.01 l reached the 25 m with a maximum intensity of
0,059 l s -1 , (39% of the inflow intensity) corresponding to a runoff rate of 23.63 %. The
duration is longer in the second run (434 sec) and starts earlier, 82 s before stopping
discharge. The r-l-factor in the first run is 2.92, in the second run 5.91. (Fig. 7a)
