Inferring Subsurface Preferential Flow Features from a Wavelet Analysis of Hydrological Signals in the Shale Hills Catchment

Abstract Preferential flow (PF)‐dominated soil structure is often considered a unique system consisting of micropores and macropores and thus supposed to provide dual‐pore filtering effects on hydrological signals, through which smoothing effects are likely to be stronger for matrix flow and weaker for PF via macropores. By using time series of hydrological signals (precipitation, canopy […]
