Figure 5. Mean arrival time and skew for permeability flume runs and numerical model simulations where the permeability a single logjam went from high to low. Both mean arrival time and skew increase as jam permeability decreases (i.e., the logjam is more tightly packed). Note that flume-derived transient storage statistics are particularly sensitive to surface water flow, while model-derived transient storage statistics only focus on flow in the subsurface (they are not directly comparable). There are no replicate runs for the numerical model results.
