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).

Effects of baseline conditions on the simulated hydrologic response to projected climate change
Changes in temperature and precipitation projected from five general circulation models, using one late-twentieth-century and three twenty-first-century emission scenarios, were downscaled to three different baseline conditions. Baseline conditions are periods of measured temperature and precipitation data selected to represent twentieth-century climate. The hydrologic effects of the climate projeAuthorsKathryn M. Koczot, Steven L. Markstrom, Lauren E. HayCharacterizing climate-change impacts on the 1.5-yr flood flow in selected basins across the United States: a probabilistic approach
The U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) model was applied to basins in 14 different hydroclimatic regions to determine the sensitivity and variability of the freshwater resources of the United States in the face of current climate-change projections. Rather than attempting to choose a most likely scenario from the results of the Intergovernmental Panel on Climate ChaAuthorsJohn F. Walker, Lauren E. Hay, Steven L. Markstrom, Michael D. DettingerSimulation of Runoff and Reservoir Inflow for Use in a Flood-Analysis Model for the Delaware River, Pennsylvania, New Jersey, and New York, 2004-2006
A model was developed to simulate inflow to reservoirs and watershed runoff to streams during three high-flow events between September 2004 and June 2006 for the main-stem subbasin of the Delaware River draining to Trenton, N.J. The model software is a modified version of the U.S. Geological Survey (USGS) Precipitation-Runoff Modeling System (PRMS), a modular, physically based, distributed-parametAuthorsDaniel J.

The U.S. Geological Survey Downsizer is a computer application that selects, downloads, verifies, and formats station-based time-series data for environmental-resource models, particularly the Precipitation-Runoff Modeling System. Downsizer implements the client-server software architecture. The client presents a map-based, graphical user interface that is intuitive to modelers; the server provideAuthorsChristian Ward-Garrison, Steven L. Markstrom, Lauren E. HayIntegrated watershed scale response to climate change for selected basins across the United States
As the questions of climate change has moved from “if” it is happening to “how” it is changing our environment, it has become important to have regional assessment designs to allow us to better understand how changes are occurring now and in the future. The authors are using the Precipitatation Runoff Modeling System (PRMS) to assess the potential effects of long-term climate change on 15 basins rAuthorsSteven L. Markstrom, Lauren E. HayUser's Manual for the Object User Interface (OUI): An Environmental Resource Modeling Framework
The Object User Interface is a computer application that provides a framework for coupling environmental-resource models and for managing associated temporal and spatial data. The Object User Interface is designed to be easily extensible to incorporate models and data interfaces defined by the user. Additionally, the Object User Interface is highly configurable through the use of a user-modifiableAuthorsSteven L. Markstrom, Kathryn M. KoczotGSFLOW - Coupled Ground-Water and Surface-Water Flow Model Based on the Integration of the Precipitation-Runoff Modeling System (PRMS) and the Modular Ground-Water Flow Model (MODFLOW-2005)
The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow requires the development of models that couple two or more components of the hydrologic cycle. An integrated hydrologic model called GSFLOW (Ground-water and Surface-water FLOW) was developed to simulate coupled ground-water and surface-water resources. The new model is basAuthorsSteven L. Markstrom, Richard G. Niswonger, R. Steven Regan, David E. Prudic, Paul M. BarlowA monthly water-balance model driven by a graphical user interface
This report describes a monthly water-balance model driven by a graphical user interface, referred to as the Thornthwaite monthly water-balance program. Computations of monthly water-balance components of the hydrologic cycle are made for a specified location. The program can be used as a research tool, an assessment tool, and a tool for classroom instruction.AuthorsGregory J. McCabe, Steven L. MarkstromStep wise, multiple objective calibration of a hydrologic model for a snowmelt dominated basin
The ability to apply a hydrologic model to large numbers of basins for forecasting purposes requires a quick and effective calibration strategy. This paper presents a step wise, multiple objective, automated procedure for hydrologic model calibration. This procedure includes the sequential calibration of a model's simulation of solar radiation (SR), potential evapotranspiration (PET), water balancAuthorsL.E. Hay, G.H. Leavesley, M.P. Clark, S.L.

The interdisciplinary nature and increasing complexity of water- and environmental-resource problems require the use of modeling approaches that can incorporate knowledge from a broad range of scientific disciplines.

A modular approach to model design and construction provides a flexible framework in which to focus the multidisciplinary research and operational efforts needed to facilitate the development, selection, and application of the most robust distributed modelling methods. A variety of modular approaches have been developed, but with little consideration for compatibility among systems and concepts. SAuthorsG.H. Leavesley, S.L. Markstrom, Pedro J. Restrepo, Roland J.
