Prediction, time variance, and classification of hydraulic response to recharge in two karst aquifers
Andrew J. Long, Barbara Mahler
2013, Hydrology and Earth System Sciences (17) 281-294
Many karst aquifers are rapidly filled and depleted and therefore are likely to be susceptible to changes in short-term climate variability. Here we explore methods that could be applied to model site-specific hydraulic responses, with the intent of simulating these responses to different climate scenarios from high-resolution climate models. We...

Relating hyporheic fluxes, residence times, and redox-sensitive biogeochemical processes upstream of beaver dams
Martin A. Briggs, Laura Lautz, Danielle K. Hare
2013, Freshwater Science (32) 622-641
Abstract. Small dams enhance the development of patchy microenvironments along stream corridors by trapping sediment and creating complex streambed morphologies. This patchiness drives intricate hyporheic flux patterns that govern the exchange of O2 and redox-sensitive solutes between the water column and the stream bed. We used multiple tracer techniques, naturally...
