Abstract

This dissertation is an investigation of the initiation of motion in aeolian sediment transport. The chapters within address transport thresholds for dry sands and spatiotemporal variability of surface moisture on natural beaches, both critical concerns for the study of aeolian processes. Results indicate a new model of transport threshold conditions provides substantial improvement in predictive capability. Field measurements closely match model predictions. In addition, results indicate that small scale variability and near surface gradients of surficial moisture are important components to aeolian systems. New techniques for measuring beach surface moisture provide improved accuracy over previous approaches.
