Abstract:

© 2017 Engineers Australia. All Rights Reserved. Design flood estimation remains a problem for many professionals involved in the management of rural and urban catchments. Recorded flood data provides the basis for most design flood estimation; the recorded flood data is used in application of the design flood estimation technique (FFA) or in the development of the technique (RFFE). In general, data used for design flood estimation is the peak flow of the flood hydrograph. However, the data recorded at most gauging stations is the water level in the channel (the channel stage). To convert these stages to an equivalent flood flow, a rating curve or a stage-discharge relationship is used. For most design flood problems, extrapolation of the stage-discharge relationship is usually required to obtain flood peak flows. There is a need to consider the magnitude of this extrapolation of the stage-discharge relationship. Furthermore, there is a need to consider the data used for development of the stage-discharge relationship and the impact of these data on the subsequent extrapolation. Presented herein will be the results of an investigation into stage-discharge relationships and their basis.
