The Webinar will have four ½ hour sessions and will begin with a brief review of the Hydraulics 101 Lectures. Uniform flow, specific energy, and gradually varied flow will be covered in the first session. Hydraulic modeling and water surface profile computations will be covered in the second session and geometric data requirements will be addressed in the third session. The final session will concentrate on the development of the Hydrologic Engineering Centers River Analysis System computer model (HEC-RAS).
The Webinar will stress the fundamental of hydraulics as applied to dam safety.
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 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.
