Abstract

In this paper, results of the Giri and Shimizu (2006) model are compared with laboratory data on bedform response to time-varying flows that produce changes in bedform morphology without total removal (so-called "washout") of bedforms. The goal of the research presented herein is to assess this method for making predictions of bedform behavior in time-varying flows and to try to identify aspects of the problem that need further research to develop this and similar methods into practical predictive tools for scientists and engineers. The experiments were carried out in the sediment transport research flume at the US Geological Survey's Geomorphology and Sediment Transport Laboratory (GSTL) in Golden, Colorado.
