Some sources and controls on nonstorm streamflow from a 19.8 ha agricultural hill land catchment located in east-central Pennsylvania were hypothesized and identified based on 18 O, Si, NO 3 , Cl and SO 4 concentration patterns. Streamflow, springflow, soil water, seepage and shallow groundwater were sampled routinely from 16 October to 20 November 1989, which included...
To increase understanding of hydrologic flow paths, two- and three-component tracer models were used to determine stormflow components on a 19.8 ha agricultural catchment in central Pennsylvania. Three events were studied during the 1989 autumn recharge period with the first and largest storm having a 5-10 year return period, 80 mm rainfall. Continuous precipitation and streamflow records were augmented...
