Roger R. Wolvington
Software Engineer
Mr. Wolvington is a software engineer with over 20 years' experience developing applications for water resources engineering. He specializes in surface water, water quality and pipe network modeling and environmental database development.
As lead programmer of Hydrosphere's network modeling tool (XLCRAM), Mr. Wolvington has developed algorithms and constructs that represent both the physical and institutional aspects of river basin and water supply systems. His code captures water allocation rules such as compacts, decrees, and contracts, and hydrologic parameters such as hydropower, bank storage, return flows, conveyance losses, salinity/water quality, exchanges, instream flows and storage accounts. He has also developed and incorporated new designs for network analysis of river basins to detect and identify errors introduced during application. Other enhancements to XLCRAM made by Mr. Wolvington include: a method of detecting equal benefit paths that could cause arbitrary solutions, re-design of the tool to support 32-bit programming environments, and implementation of object-oriented structures. Mr. Wolvington has also played critical roles in the application of Hydrosphere's network modeling tool to the North Platte River basin, the Colorado River basin, the South Platte River basin, the Arkansas River basin and the Gunnison River basin.
Mr. Wolvington developed code to analyze TCE contamination through the simulation of water storage tanks, pumps, valves, and pressure-based pipe networks. He has produced several analytical software programs to facilitate the analysis of large volumes of both water quality and quantity data at daily and hourly time steps. He has also created tools for ammonia concentration analysis and modeling.
Mr. Wolvington has developed database applications using SQL, Microsoft Access, dBase III, and proprietary binary database systems. He played a key role in the development of environmental databases on CD-ROM. Mr. Wolvington is an expert in C/C++, Modula-2, Visual Basic (and Visual Basic for Applications), Delphi, Pascal and FORTRAN and has used several operating systems including Microsoft Windows, Linux, and DOS.
Mr. Wolvington holds a BS in Electrical Engineering from the University of Colorado.
