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.

史蒂文·纳米卡斯（Steven L. 将在加利福尼亚州Pismo Beach州立公园进行一个两期野外项目，以允许在一系列风条件下收集数据。 将收集所有关键盐参数的同时高频测量。 这些将用于研究盐的子过程之间的相互作用，并检查它们对风相化变异性的影响。 总体研究目的是将对现有风险运输模型的研究中的短期变化结合在一起，从而提高我们的预测建模能力以及我们应对风吹沙的环境和地貌后果的能力。
