Estimation of Flood Volumes and Simulation of Flood Hydrographs for Ungaged SmallRural Streams in Ohio

摘要

The report summarizes the methods of data collection and analysis for this studyand presents the equations developed to estimate flood-volume frequency and basin lagtime. It also presents a method of simulating flood hydrographs by applying estimated basin lagtime and peak discharge to a dimensionless hydrograph. Finally, step-by-step examples are given showing how to use the equations and how to simulate flood hydrographs. The equations and methods developed are applicable to small rural streams in Ohio whose basin characteristics are similar to the basin characteristics of the study sites.
