Introduction to Hydrologic Modeling Using Geospatial Information

Arthur C. Miller, Ph.D., P.E., CFM, Science Practice Leader, AECOM. Dr. Miller is a nationally recognized expert in hydrology, hydraulic engineering, and dam safety.  He is a Distinguished Professor Emeritus of Civil and Environmental Engineering at Penn State University, where he was the head of the Water Resources Group prior to joining AECOM in 2006 as a Science Practice Leader.  He has over 40 years of experience in water resources performing research, consulting and publishing in hydrology, hydraulics, floodplain delineation, dam safety, bridge scour, river mechanics and sediment transport.  Dr. Miller served as Chair of the Energy Power Research Institute (EPRI) Task Committee on Standards for PMP for Dam Safety Analysis, he served on the Task Committee of ASCE that established their National Guidelines for the Hydrologic Safety of Dams and served as Chair of a Task Committee for FERC that established their Federal Guidelines for Dam Safety, he co-authored their chapter on hydrologic computations dealing with reservoir analysis.  In 2007, he was awarded the ASDSO Hampton Medal for outstanding contributions to research and practice in hydrologic and hydraulic engineering for dams.

Amanda J. Hess, P.E., CFM, H&H Group Manager, Gannett Fleming, Inc. Ms. Hess is a Hydrology and Hydraulics Group Manager and Senior Project Engineer in the Dams and Hydraulics Section of Gannett Fleming, Inc.  Amanda received her bachelor’s and master’s degrees in civil engineering from Pennsylvania State University under Dr. Arthur Miller.  She has over 15 years of experience working on dams, flood control projects, and water supply systems.  She is responsible for leading a team of engineers to perform hydrologic and hydraulic analyses for water resources projects and design hydraulic structures related to flood control reservoirs, dams, bridges, and channel improvement construction, rehabilitation, and reconstruction projects, including the design of spillways, outlet works, and stilling basins.  Amanda regularly instructs courses on hydrologic and hydraulic modeling.

Christopher D. Krebs, P.E., CFM, GISP. Vice President, Gannett Fleming, Inc. Mr. Krebs is Vice President and the Manager of GIS Services for Gannett Fleming, Inc. where he is responsible for leading the integration of spatial technologies with the everyday engineering and planning practices of the firm's Environmental Resources Division.  Chris has over 20 years of experience in utilizing geographic information system software to support engineering projects some of which include FEMA flood studies, storm water master plans, water supply modeling, and dam failure studies.  He is a certified ArcGIS Desktop Professional that has been developed numerous custom GIS applications related to digital terrain modeling, and flood and dam break modeling with HEC-HMS and HEC-RAS.
