AAWRE is pleased to announce the election of Dr. David T. Williams, Ph.D., P.E., P.H., CFM, CPESC, D.WRE, F.EWRI, F.ASCE as the At-Large Trustee on the AAWRE Board for 2021-2024.  Dr. Williams will begin his tenure on the Board beginning in October.

Dr. Williams has over 45 years of professional experience in the water resources industry and is known nationally and internationally for his contributions to the industry.  He served as Principal-in-Charge for several FEMA flood insurance studies in San Diego and Orange counties.  He has written the new HEC-6 User Manual for the U.S. Army Corps of Engineers Hydrologic Engineering Center, performed HEC-6 and local scour analysis of pipeline crossings in Arizona and New Mexico, headed the Keene Ranch groundwater modeling study and the Nile River sedimentation evaluations for the World Bank.  He is well versed in the computer programs HEC-1, HEC-HMS, HEC-2, HEC-RAS, HEC-6, STORM, and WQRRS.

Dr. Williams is also a recognized expert in sedimentation engineering and in developing innovative solutions to difficult hydraulic and hydrologic design problems in rivers and estuaries.  David has served as chair of the ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability and is past-chair of the EWRI Sedimentation, Computational Hydraulics, Stream Restoration, and Probabilistics (now Risk, Uncertainty and Probabilistic Approaches) Committees.  Dr. Williams was formerly an Associate Editor of the ASCE Journal of Hydraulic Engineering, as well as a reviewer.

With the exception of the 2019 and 2020 conferences, he has attended every EWRI (and Hydraulics Division) conference since 1978, either presenting a paper, on a discussion panel or session moderator.  Dr. Williams served as a two time President of the International Erosion Control Association and he served as a committee member of ASTM A05.12 (Wire specifications), where he helped develop the standards for both welded and twisted (woven) gabions.  He also served on ASTM D18.25 (Erosion Control Products), where he helped develop a variety of standards related to erosion control.  David was the chair of the Federal Interagency Technical Committee on Sedimentation when he was with the U.S. Army Corps of Engineers.

He is the author of more than 200 technical papers and reports on hydrology, hydraulics and sedimentation.  He was selected the 1993 Small Business Person of the Year by the Carlsbad, California Chamber of Commerce, and served as chair of the Carlsbad Beach Erosion Committee.  His professional experience includes more than 18 years as a hydraulic engineer with the USACE at the Waterways Experiment Station (WES, now ERDC) in Vicksburg, MS, both the Nashville and Baltimore Districts, and the Hydrologic Engineering Center (HEC) in Davis, California.  At HEC, he worked on the development of the cohesive and network versions of the HEC-6 sediment transport computer model, co-wrote the Reservoir Sedimentation Chapter of the USACE’s Engineering Manual on Sedimentation Investigations, helped in the development of spatial data management techniques and evaluation of the economic benefits of flood control projects.

Dr. Williams was acting Chief of the Hydrology and Hydraulics Section at the Baltimore District Corps of Engineers.  He has been a frequent short course instructor for ASCE, Federal and State Agencies for computer training workshops on using HEC-2, HEC-RAS, HEC-HMS and HEC-6. In addition, he has taught short courses on channel bed scour for toe protection design, sediment transport, fluvial geomorphology, risk and uncertainty, bridge scour, stream restoration and streambank protection.  Dr. Williams is a founding Diplomate of the AAWRE since 2005 and he has instructed the AAWRE's How to Serve as an Expert Witness sessions at the EWRI Congress for the past ten years. He is a proud graduate of the University of California, Davis and Colorado State University.

David stated: "I am grateful and honored for the opportunity given by my peers to further serve my profession as the At-Large Trustee for AAWRE.  All that know me also know that I am dedicated and passionate about being a water resources engineer and I will use that passion to help implement the work as envisioned by the AAWRE Board over the next few years and beyond.  I see many technical, societal and ethical challenges for the Board and look forward to embracing those challenges so that we can leave a better world for our children.”
