Description
Summary:Increased knowledge of hydrology is essential to an understanding of the water quality function of stream riparian zones. We examined the effect of upland surficial aquifer size, topography and riparian sediment lithology on the subsurface hydrology of eight riparian sites on glacial till and outwash landscapes in southern Ontario, Canada. Riparian sites had a permanent subsurface hydrologic connection to the adjacent upland in landscapes where upland permeable sediment depths were 2–15 m. In contrast, a hydrologic connection was absent in summer and autumn at riparian sites with 5%. Where the riparian zone was level to gently sloping (
