Evaluation of Accuracy of Aeolian Velocity Measurement Using Image Analysis

Abstract

Study on Aeolian transport began in 1941 when Bagnold first conducted a study on aeolian transport in desert conditions. Aeolian transport study was mainly conducted on deserts, and the field of coastal engineering began with the application of Bagnold’s equation to the coast after 1980. However, many studies have shown that using the Bagnold equation on the coast overestimates the amount of aeolian transport. Currently, aeolian trap using various sensors ranging from simple forms have been developed and are being used in study. However, these aeolian traps have the disadvantage that there is a large difference in performance for each trap. In addition, in the case of existing traps, analysis is performed only on the amount of sand collected, and quantitative analysis of sand transport velocity or concentration is difficult. Therefore, in this study, we use image analysis techniques to evaluate the accuracy of aeolian transport velocity measurement and suggest a method that can be used in the study.
