The past decade was the wettest on record for much of central and eastern North America. Near beginning this period regional water abundance, however, drought conditions reinforced concerns that high temperatures evapotranspiration foreshadowed a persistent imbalance in hydrologic cycle characterized by loss. These fluctuating were manifest level variability Laurentian Great Lakes, largest syst...

A watershed model can be used to better understand the relationship between land use activities and hydrologic and water quality processes occurring within a watershed. Two different models, SWAT (Soil and Water Assessment Tool) and HSPF (Hydrologic Simulation ProgramFortran), were selected in this study to simulate stream flow, sediment, and nutrients loading from the Polecat Creek watershed i...

Article history: Received 25 June 2015 Received in revised form 22 January 2016 Accepted 1 February 2016 Available online 11 February 2016 In Central America, seasonal and interannual shifts in the position of the Intertropical Convergence Zone (ITCZ) control the hydrologic budget. To better understand long-term changes in regional ITCZ-driven precipitation we re-examined a coral δO record from...

Climate models simulate an intensifying Arctic hydrologic cycle in response to climatic warming, however the role of surface-atmosphere interactions from degrading frozen ground is unclear in these projections. Using Modern-Era Retrospective Analysis for Research and Applications (MERRA) data in high-latitude Eurasia, we examine long-term variability in surface-atmosphere coupling as represente...

[1] Intensification of the Arctic hydrologic cycle and permafrost melt is expected as concentrations of atmospheric greenhouse gases increase. Quantifying hydrologic cycle change is difficult in remote northern regions; however, monitoring the stable isotopic composition of water runoff from Arctic rivers provides a means to investigate integrated basin-scale changes. We measured river water an...
