A Simple, Regional Characterization of Wave-Generated Ripple Geometry and Orientation

Abstract

The goal of this study is to provide a simple, regional characterization of wave-generated ripple spacing, height and orientation through time. The approach is being tested against data collected during the Ripple DRI in association with the SAX04 field experiments as well as future Ripple DRI field campaigns. This project revisits the Wiberg and Harris (1994) method for calculating ripple geometry with three objectives in mind: 1) to review the literature for wave-generated ripple measurements made since our 1994 compilation, compare them to the ripple scalings we developed, and update our model as necessary; 2) to couple the ripple calculations with the SWAN and/or WaveWatchIII wave model to consider the regional-scale spatial and temporal distribution of wave-formed ripples; and 3) extend the wave ripple calculations to include ripple realignment and degradation.
