Steve Markstrom is a hydrologist with the USGS National Research Program, Central Region, Denver, Colorado. He has been a member of the Precipitation-Runoff Modeling research group since 1991. The research group has the broad goal of understanding precipitation-runoff processes and developing improved hydrologic models.

Steve Markstrom has worked as hydrologist at the USGS National Research Program, Central Region, Denver, Colorado since 1991 where he is a member of the Precipitation-Runoff Modeling research group. The research group has the broad goal of understanding precipitation-runoff processes and developing improved hydrologic models. He is currently part of the team developing an integrated gound- and surface- water simulation model (GSFLOW). He is a technical team leader for the Watershed and River Systems Management Program (WARSMP), a cooperative effort between the USGS and US Bureau of Reclamation to develop decision support systems and tools that integrate physically based process models and resource management models. Also, he develops and supports the Modular Modeling System (MMS).

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 areas. T

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. The USGS Modeling of Watershed Systems (MoWS) group is currently developing the infrastructure for a National Hydrologic Model (NHM) to support coordinated, compre

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 standard value

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).
