Inter-annual and spatial variability of Hamon potential evapotranspiration model coefficients Inter-annual and spatial variability of Hamon potential evapotranspiration model coefficients
Monthly calibrated values of the Hamon PET coefficient (C) are determined for 109,951 hydrologic response units (HRUs) across the conterminous United States (U.S.). The calibrated coefficient values are determined by matching calculated mean monthly Hamon PET to mean monthly free-water surface evaporation. For most locations and months the calibrated coefficients are larger than the...

Evaluation of statistically downscaled GCM output as input for hydrological and stream temperature simulation in the Apalachicola–Chattahoochee–Flint River Basin (1961–99) Evaluation of statistically downscaled GCM output as input for hydrological and stream temperature simulation in the Apalachicola–Chattahoochee–Flint River Basin (1961–99)
The accuracy of statistically downscaled general circulation model (GCM) simulations of daily surface climate for historical conditions (1961–99) and the implications when they are used to drive hydrologic and stream temperature models were assessed for the Apalachicola–Chattahoochee–Flint River basin (ACFB). The ACFB is a 50 000 km2 basin located in the southeastern United States. Three...

Understanding the Impacts of Glaciers on Streamflow in Alaska and Washington
Glaciers are a central component to the hydrology of many areas in Alaska and the Pacific Northwest. Glacier melt plays a crucial role in the movement of nutrients through a landscape and into the ocean, and the flow of water into streams that sustain many species. As air temperatures rise, increased rates of glacier melt may have significant impacts to the hydrology and ecology in these...
Developing a VisTrails Platform for Modeling Streamflow Hydrology and Projecting Climate Change Effects on Streamflow
Hydrologic models are used throughout the world to forecast and simulate streamflow, inform water management, municipal planning, and ecosystem conservation, and investigate potential effects of climate and land-use change on hydrology.

Southeast Regional Assessment Project (SERAP): Assessing Global Change Impacts on Natural and Human Systems in the Southeast
The Southeastern United States spans a broad range of physiographic settings and maintains exceptionally high levels of faunal diversity. Unfortunately, many of these ecosystems are increasingly under threat due to rapid human development, and management agencies are increasingly aware of the potential effects that climate change will have on these ecosystems. Natural resource managers...
