There are three keynote speakers for the SEHDYD 2019 conference. The following provides a short biography, title of the presentations, and the abstract for each keynote speaker.

Dr. George Annandale, Consultant

Dr. Annandale has more than forty years of experience as a civil engineer specializing in water resources engineering. He offers services in the fields of hydrology and hydraulics, scour of rock and sustainable development of water resource infrastructure, focusing on reservoir sedimentation management, dam safety and climate change assessment.

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 Water Power and Dam Construction as one of 20 engineers who globally made a significant contribution to dam engineering.

He is known for his expertise in reservoir sedimentation management, having authored one of the first books on this topic, having co-developed the Life Cycle Management Concept for the World Bank, and having globally worked on numerous reservoir sedimentation management projects. The first book he authored, entitled “Reservoir Sedimentation”, deals with technical aspects of sediment deposition, while the books “Quenching the Thirst”, “Reservoir Conservation: The RESCON Approach” and “Extending the Life of Reservoirs” focus on sustainable management of water resource infrastructure; addressing the effects of climate change and reservoir sedimentation on water and power supply reliability.

Dr. Annandale’s keynote presentation is entitled “Reservoir Storage: Slowly Drifting into Failure?”


Dr. Lauren Hay, USGS

Dr. Lauren Hay has worked for the USGS since 1986. She is currently a research hydrologist residing in the Earth Systems Modeling Branch of the Integrated Modeling and Prediction Division of the Water Mission Area in Denver, Colorado. Prior to that she was the lead scientist for the Modeling of Watershed Systems research group for the now defunct National Research Program. Her research has the broad goal of understanding precipitation-runoff processes and developing improved hydrologic models.

Dr. Hay’s keynote presentation is entitled “The National Hydrologic Model: An Infrastructure for Collaboration in the Hydrologic Community”


Kristina Swallow, P.E., ENV SP, F.ASCE, ASCE President 2018

Kristina Swallow is the past president of the American Society of Civil Engineers (ASCE). Kristina is a civil engineering leader with more than twenty years of professional practice in water resources, transportation, and land development.
