Interpretive Summary: In spite of strenuous efforts over the last half century, the engineering prediction of flow and sediment transport over bedforms, in general, and dunes, in particular, still presents a major obstacle in the solution of sedimentation problems in alluvial channels. For a given flow rate in a stream channel, predicting the flow depth and sediment transport rate has a large degree of uncertainty, and much of the difficulty can be traced to the development of bedforms. As a step forward in this process, an ASCE Task Committee has been organized with the aim of examining and synthesizing state-of-the-art knowledge concerning flow and sediment transport over dunes, emphasizing the progress over the past 20 years. Specific topics will include the equilibrium dune bed, transitory conditions of developing dunes, and other complications in bedform development and mechanics, including sediment heterogeneity. This committee, working with researchers from a variety of disciplines around the world, will publish in Journal of Hydraulic Engineering a series of papers examining each of these topics.
