Integration of Stream Flow Duration with Hydraulic Geometry in the Southern Piedmont

Proceedings of the 2013 Georgia Water Resources Conference, April 10-11, 2013, Athens, Georgia.Stream hydrology is often described based on five fundamental properties of a river’s flow regime: magnitude, frequency, duration, timing, and rate of change. Flow duration curves provide a powerful tool for integrating magnitude, frequency, and duration. Though flow duration curves have been well established at regional scales, the correspondence between in-stream flow duration and the duration of flood events onto adjacent floodplains has not been adequately explored especially at subwatershed and stream reach scales. By combining flow duration curves with channel geometry, site-specific stage duration curves and flood duration can be created. Herein, flow duration curves are used in conjunction with channel hydraulic geometry to estimate flood duration of southern Piedmont floodplains.Sponsored by: Georgia Environmental Protection Division; U.S. Department of Agriculture, Natural Resources Conservation Service; Georgia Institute of Technology, Georgia Water Resources Institute; The University of Georgia, Water Resources Faculty.This book was published by Warnell School of Forestry and Natural Resources, The University of Georgia, Athens, Georgia 30602-2152.
