Figure 2. Mean arrival time and skew for flume runs and numerical model simulations where the longitudinal distribution density of logjams went from a one logjam (single) to five logjams (multiple). Both mean arrival time and skew increase with multiple jams. 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.
