Abstract:

A protocol is established to evaluate nine methods for defining hydrographs. Data from one site are used. The context is a need for dynamic hydraulic analysis to downsize drainage structures resulting from designs developed by using conservative steady-state flow assumptions. In addition, the analysis addresses a situation in which measured rainfall or runoff data are missing at a site. Data are generated for a hypothetical site and data requirements and computational methods are evaluated. The test results indicate that Snyder's method and its modification by Constant are superior. The protocol appears to be general enough to use in a comprehensive evaluation of hydrograph generation methods for use in ungauged watersheds. The comprehensive evaluation would draw on a national database and would determine criteria for selecting appropriate hydrograph generation methods to support dynamic hydraulic analysis.
