New experiments on aeolian sand transport have been conducted on two Belgian beaches in the period between 2016 and 2018. Meteorological variables and aeolian sand transport rates were simultaneously measured on the subaerial beach. The field study aims to provide insight into the relationship between the transport rate of dry sand and shear velocity. Previous results from similar field studies were included to extend the dataset. Various aeolian sand transport models, predicting equilibrium transport rates for dry sand, were evaluated. The key parameter in all these aeolian models is the shear velocity (u_*) derived from the measured velocity profiles. Mean shear velocities at the Belgian beaches were averaged over 10-minute periods and ranged from 0.2 to 0.7 m/s. Transport rates of dry sand ranged from 2 to 37 g/m/s. Zingg’s 1953 model produced the best results for the field data. Still, a large variability is found in the datapoints, advocating the need of high-quality field data on aeolian sediment transport.

2016 年至 2018 年期间，在比利时的两个海滩上进行了新的风沙输送实验。同时在地下海滩上测量了气象变量和风沙输送率。实地研究旨在深入了解干砂的输送速率与剪切速度之间的关系。包括先前类似实地研究的结果以扩展数据集。对预测干砂平衡输送速率的各种风积砂输送模型进行了评估。所有这些风成模型中的关键参数是剪切速度 (u _*) 来自测得的速度剖面。比利时海滩的平均剪切速度在 10 分钟内取平均值，范围为 0.2 至 0.7 m/s。干砂的传输速率为 2 至 37 g/m/s。Zingg 1953 年的模型对现场数据产生了最好的结果。尽管如此，在数据点中发现了很大的可变性，这表明需要关于风成沉积物运输的高质量现场数据。
