Uranium isotopes (234U/238U) were measured in eight well-studied boreal streams of different sizes and characters and in seven deep groundwater wells (up to 11m deep) adjacent to these streams. The measurements covered an entire spring flood cycle, from winter baseflow conditions, through the peak flow and into the early summer, thereby capturing much of the hydrological dynamics in these systems...
We present a framework for evaluating and communicating effects of human activity on water quality in managed forests. The framework is based on the following processes: atmospheric deposition, weathering, accumulation, recirculation and flux. Impairments to water quality are characterized in terms of their extent, longevity and frequency. Impacts are communicated using a “traffic lights” metaphor...
The effect of catchment scale and the influence of landscape characteristics on runoff generation were investigated during snow melt in 15 nested boreal streams within the Krycklan catchment in northern Sweden. We used detailed oxygen-18 analyses of soils from two characteristic landscape types, snow melt samples and water samples from 15 streams with subcatchments ranging in size from 0.03 to 67km...
