david-dawdyDavid Dawdy is a distinguished hydrologist, with over 60 years of experience in research, teaching and consulting.  He began his career at the USGS surface water branch in 1951, working with Luna Leopold and Walter Langbein.  He has made fundamental contributions to many topics in hydrology, including flood frequency analysis, hydrologic modeling, worth of hydrologic data and data network design for various water resource inventory purposes as well as scientific hypothesis testing, characterizing resistance to flow in alluvial channels, mapping flood hazard zones on alluvial fans, and urban hydrologic modeling practice.  The author of over 100 papers in hydrology, he has received numerous honors, including the Ven Te Chow Award and the Arid Lands Hydraulic Engineering Award from the ASCE, and the Ray K. Linsley Award from the American Institute of Hydrology (AIH), and was named a Fellow of the AGU in 1990. He has served on the AGU committees on surface water, sedimentation and the history of hydrology, and served for 12 years on the editorial board of the AGU Water Resources Monograph Series.  He was instrumental in initiating the AGU History of Hydrology Interview series starting in 1995. David Dawdy received a MS in Statistics from Stanford University and a BA in History from Trinity University, and was on the faculty of the Civil Engineering Department at Colorado State University.
