I develop and teach short courses for regional and international watershed modeling and management planning.
Introduction to EcoHydRological Modeling
I have developed and maintained short courses related to Ecohydrological modeling with the R statistical language. These courses have centered around student, watershed manager, and researcher use and adaptation of the CRAN distributed EcoHydRology software libraries.
Scope: Regional and International.
Including Topographical Driven Processes into the SWAT and APEX Watershed Models
I have developed and maintained short courses for integrating deterministic topographically driven processes into the SWAT and APEX watershed modeling systems. These short courses developed for watershed managers, students, and researchers, have been in support of the TopoSWAT ArcGIS toolbox that interfaces with the ArcSWAT watershed modeling GIS interface.
Scope: Regional and International
Forcing Hydrological Models Anywhere
I have developed and maintained short courses for interfacing global weather data sets with surface hydrological process models. These courses are developed for watershed managers, students, and researchers, supporting hydrological process models in any form from spreadsheet based, to higher level computer language based, to complex GIS interfaced modeling systems.
Scope: Regional and International.
I am a research scientist and engineer with 20 years of professional experience in complex problem solving and high performance computing. I work primarily as a scientific modeler bridging numerous fields to provide solutions that are better than solutions currently in existence in any one field. My current research involves coupling atmospheric modeling systems and re-analysis data sets with process based surface hydrological models, and refining land surface models to be more “process based” requiring less localized calibration and making them usable in modeling climate change.
My postdoc has been dedicated to building the foundational basis for my continued research. Significant projects include:
- Optimizing access into the massive weather and atmospheric datasets allowing researchers and watershed managers to perform atmospheric to hydrological coupling for any location in the world. Datasets we are currently coupling to are the 32 year hourly deterministic forecast based simulations initialized with reanalysis time steps from 1979 to present.
- Building toolsets to dynamically generate surface characterization parameterizations for any watershed in the world based off of global soil pedon dataset and globally available elevation models.
- Establishing cross scientific field domain and cross institutional research teams to optimally transcend into significant new scientific breakthroughs. These teams tightly couple the Virginia Tech Biological Systems Engineering Department to several of the leading atmospheric, oceanographic, and computational and information systems science collaboration teams around the world.
