Abstract

The goal of this study is to provide a technique that could be used to rapidly characterize grain sizes of remote sites with acceptable levels of accuracy. The AA. use the mixed-sediment beach of the Elwha River delta (Warrick et al., 2009) for method development and application, and demonstrate its potential transferability with an assessment of a mixed-sediment beach of Kachemak Bay, Alaska. The approach is considerably less sensitive to lighting conditions than object-detection methods. The effects of wet and dry conditions are also evaluated and discussed
