Steven L. Namikas University of Southern California The doctoral dissertation research will involve a comprehensive field investigation of the saltation process and its influence on aeolian transport rates. A two phase field project will be undertaken at Pismo Beach State Park, CA to allow data collection under a range of wind conditions. Simultaneous high frequency measurements of all key saltation parameters will be collected. These will be used to investigate the interaction between the sub-processes of saltation and examine their influence on short term variability in aeolian transport. The overall research objective is to incorporate understanding of short term variations in transport gained in this research into existing models of aeolian transport and thereby improve our predictive modeling capabilities and our ability to deal with the environmental and geomorphic consequences of wind blown sand.

南加州大学的史蒂文·L·纳米卡斯大学的博士论文研究将涉及对跃迁过程及其对风沙输送速率的影响的全面实地调查。将在加利福尼亚州皮斯莫海滩州立公园进行一个两阶段的实地项目，以便在各种风力条件下收集数据。将收集所有关键跃迁参数的同步高频测量数据。这些将被用来研究跃迁的子过程之间的相互作用，并研究它们对风沙输送的短期变异性的影响。总体研究目标是将这项研究中获得的对风沙输送短期变化的理解纳入现有的风沙输送模型，从而提高我们的预测模拟能力和我们处理风沙的环境和地貌后果的能力。
