Spatial and temporal structure within moisture measurements of a stormwater control system

•Water content reflectometers measured permittivity beneath porous pavement and in soil.•Geostatistical characterization indicates that spatial correlation is not present in aggregate media.•A novel two-stage para-statistical model was developed to evaluate pavement clogging effects.•Novel data reduction methods are presented which are also applicable to other geospatial studies.•Quantile patterns illustrate unique rainfall-permittivity responses in aggregate and soil. This study develops novel geostatistical methods to investigate the spatial relationship between individual soil moisture sensors placed within native soil and #57 crushed stone aggregate subbase. The subbase sensors are beneath a 0.06ha (0.15acre) pervious concrete parking lot in Cincinnati, OH, USA. The parking lot treats runon from a 0.198ha (0.49acre) asphalt area. A geostatistical characterization of moisture (measured as permittivity) in the subbase beneath pervious concrete indicates that significant spatial correlation is either not present or only present at very short distances (
