Groundwater-surface water exchange within montane and alpine regions of the Front Range and Rocky Mountains, Colorado
Climate-change modeling scenarios have projected that drought will be more likely to occur in dry regions of the world, surface-water and groundwater availability is likely to decrease, and water quality will be negatively impacted. Characterizing how excess nutrients and pollutants are naturally …

Impacts of climate change on stream hydrologic and geochemical fluxes
In the western U.S. climate change is causing more precipitation to fall as rain rather than snow. Precipitation shifts are decreasing total groundwater recharge, ultimately changing the way that groundwater is stored and transported before it contributes to streams. However, hydrologists don’t …

Expansion of bioenergy crops in the midwestern United States: implications for the hydrologic cycle under climate change
… the potential for significant impact on the hydrologic cycle in the region. This issue is further exacerbated by the uncertainty in the response of the vegetation under elevated CO2 and temperature. This study attempts to capture the eco-physiological acclimations of bioenergy crops under …

Assessment of irrigation use on crop yield and water supplies in the Midwestern U.S.
… plays an important role in many aspects of hydrological and agricultural systems. Temperature and precipitation are usually the main forcing inputs for hydrological and agricultural simulations, while wind effect has generally been neglected in previous research. Wind speed is, however, an …

Hydrologic Response to Conifer Removal and Upslope Harvest in an Encroached Montane Meadow
… larger river watersheds because of their unique hydrologic and ecological functions. Due to climate change, over grazing, and fire suppression, conifer encroachment into meadows has accelerated. In some western regions, nearly half of all meadow habitat has been loss due to conifer encroachment. …

Connectivity dynamics and its impact on material flux and transformations in a watershed
… within and between catchments. Catchment hydrologic connectivity can be described as the emergent property of a system resulting from the interaction of its inherent landscape properties, weather events, and the changing climate, as well as the influence of these factors on the ability of …

Lacustrine Turbidites from Tropical African Lakes as Indicators of Hydrologic and Climatic Changes
… in lake basins are proven indicators of hydrologic changes, yet their usefulness as recorders of tropical paleoclimate variability has long been overlooked. The primary focus of this dissertation research is to investigate the late Quaternary hydroclimatic changes in tropical Africa, …
