Most of marine debris are mainly supplied from inland area, however there is no monitoring data for floating-litter transport from river to ocean due to no 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 an image processing technique in which a scatter- and mass-type of litters are separately analyzed. The results indicated that L evaluated by the present methods were in good agreement with the observed data in the Mogamigawa River, demonstrating the fundamental performance of the present monitoring method.
