EXPERIENCE NARRATIVE Mr. Harding has more than thirty-five years of diverse experience in water resources engineering. For more than twenty years he has focussed his practice on the design, development, and use of hydrologic and river/reservoir system models, decision support systems, hydraulic models, water-quality models, GIS, and databases. This experience includes over twenty years of project management, successfully directing engineers, scientists, and programmers in these areas. Mr. Harding currently leads Hydrosphere's efforts in the areas of forecasting, assessing climate change impacts, and the use of paleohydrology. He recently developed the first probabilistic analyses of water availability in the Colorado River Basin based on several different reconstructions of paleo flows. Mr. Harding has considerable recent experience with the development and use of Monte Carlo analyses in water resources and environmental science. Mr. Harding has served as an expert witness in original jurisdiction interstate compact litigation. In addition, he has served as an expert witness regarding the fate of toxic compounds in municipal water distribution systems and the estimation of human intakes of contaminants. He has applied Monte Carlo techniques to the estimation of human intakes of chemicals. Mr. Harding also has extensive experience managing and conducting the application of GIS to water resources investigations. His experience includes the development of extensive spatial databases of parcel and land use data and their application for estimating municipal water use. He managed the development of nationwide databases of streamflow, meteorological and water quality data. He is experienced with largescale data conversion, coordinate systems, issues of precision and scale, data sources, and the design and development of relational databases. Mr. Harding combines his experience and interest in water resources engineering with experience in the development of computer software, some of which is commercially marketed. Mr. Harding is fluent or has a working knowledge of several computer languages and has experience with the management of software and database development projects. Mr. Harding was the project manager and a principal author for Incentive Pricing Handbook for Agricultural Water Districts, written for the U.S. Bureau of Reclamation. (This document can be found at: http://www.usbr.gov/waterconservation/publications.html.) Following up on that work, Mr. Harding assisted the Mid-Pacific Region of Reclamation in developing Incentive Pricing Best Management Practice for Agricultural Irrigation Districts. Mr. Harding received his B.S. degree from the University of Colorado in 1971. He has been a registered engineer in Colorado since 1979.
