Most hydrological model studies assume constant soil properties. When Lee et al.  redid one of the most famous hillslope hydrological experiments at the Coweeta Hydrologic Laboratory, their results showed that soil properties can change significantly within several decades. This is a very important finding. The outflow from the flume changed considerably compared to the original experiment due to a leak in the concrete. This allowed the researchers to determine the effect of permeable bedrock on hillslope outflow. Above all, the manuscript highlights the usefulness in redoing an experiment many decades later.
