Fig. 5. Results of a field test. Top: Time series of the upslope water supply and surface discharge rate 2-m downhill. Bottom: Time series of water level with time resolution of 30 s. Each line represents the mean value of six probes mounted on one crossbar with a defined distance to the upslope supply (Fig. 2). The vertical bars represent the standard deviation of the water level at the respective points. The arrow points to an abrupt increase in water supply to reveal the lag in water level changes.
