Most marine debris are primarily supplied from inland areas; however, few monitoring data exist for floating-litter transport from rivers to the ocean due to the absence of appropriate monitoring methods. In this study, we developed an automatic and continuous monitoring technique for floating-litter transport L in rivers by using an image monitoring and processing technique in which different types of litter (scatter-type and mass-type) are separately analyzed. The results indicated that L evaluated by the present methods was in good agreement with the observed data in the Mogami River, Yamagata, Japan, demonstrating the fundamental performance of the present monitoring method.
