ABSTRACT

This study proposes a novel technique for soil characterization, utilizing laser transmission to observe the sedimentation process. This method significantly diminishes specimen disturbances, human errors, and the required sample size, making it a more time and cost-effective alternative to traditional methods. Detailed models capturing the intricacies of the sedimentation process, including influential factors such as particle diameter and mass concentration, are delineated. Moreover, we suggest a method to extrapolate the cumulative grain size distribution from the laser transmission profile of a soil sample. Collectively, this research presents an efficient and promising approach to soil characterization, leveraging laser light for sedimentation monitoring.
