Reservoir Sedimentation and Sustainable Management

Dr. Annandale has more than 45 years of experience as a civil engineer specializing in water resources engineering.  He has published numerous peer-reviewed papers and is author and co-author of five books on sedimentation and scour. He was named by International Waterpower and Dam Construction as one of 20 engineers who globally made a significant contribution to dam engineering. He specializes in scour of rock and sustainable development of water resource infrastructure; focusing on reservoir sedimentation management, dam safety and climate change assessment. 

Dr. Gregory Morris is a professional engineer having extensive international experience working with sediment management in reservoirs and rivers. His professional experience includes consulting on sediment management problems in reservoirs on 5 continents. He is co-author of Reservoir Sedimentation Handbook (McGraw-Hill,1998), the first comprehensive publication on this topic, Extending the Life of Reservoirs (World Bank, 2016), and numerous other publications. 

Paul is the Regional Technical Specialist for Sedimentation and Alluvial Processes for the USACE Northwest Division in Omaha, NE. He has 18 years' service as Hydraulic Engineer, Regional Technical Specialist, and Project Manager in sediment related fields. He also has experience with hydraulic design using HEC-RAS, HEC-6T, RMA2, SED2D, ADH, and GSTARS-HTC, as well as managing engineering teams for various studies. Paul's experience includes a wide variety of field work including terrestrial and hydro surveying, sediment sampling, on-site management, and problem solving. He is the current chair of the SEDHYD Sedimentation Committee.

Currently, Paul's activities include being a team leader for 2-D Modeling with the Missouri River Recovery Program Habitat Assessment and Monitoring Plan (HAMP). He also takes part in the Lewis and Clark Lake Sediment Management/Flushing Study and serves as the Omaha team lead for the USACE Regional Sediment Management Program. In addition, he is the point of contact for sedimentation issues on the Missouri River Basin within USACE; and serves as the Technical Liaison for Missouri River Flow Frequency Update. Paul is also involved with Reservoir Sustainability Planning and Analysis and is the agency lead for the development of the Geomorphic Data Exchange Portal.

Tim Randle was formerly a Supervisory Civil Engineer (Hydraulics) and Manager of the Bureau of Reclamation's Sedimentation and River Hydraulics Group.  He received his B.S. in Civil Engineering from the University of Utah and his M.S. and Ph.D. in Civil Engineer from the University of Colorado.

Tim Randle is a registered professional engineer, member U.S. Society on Dams, member of the American Society of Civil Engineers, and a Diplomate, Water Resources Engineer for the American Academy of Water Resources Engineers. He presently serves as chair of the National Reservoir Sedimentation and Sustainability Team, board member for SEDHYD, Inc., and serves on the SEDHYD Sedimentation Committee. He is past Chair of the interagency Subcommittee on Sedimentation.

Tim Randle served the Bureau of Reclamation for 40 years—nearly all of that time with the Sedimentation and River Hydraulics Group.   He has developed several computer models and conducted geomorphic and hydraulic studies of many rivers throughout the western United States. He led an EIS for the reoperations of Glen Canyon Dam to deliver water, generate power, and improve environmental conditions in Grand Canyon. He provided the sediment management expertise for the Elwha River Restoration Project.  In 1997, he was honored as Reclamation’s “Engineer of the Year” and named one of the top ten Federal Engineers by the National Society of Professional Engineers.  In 2016, he received the Distinguished Service Award from the U.S. Department of the Interior.
