On August 31, 2016 the Typhoon Lionrock landed on Primorsky Krai, Russia causing heavy rain
fall over around the border between the Russia and North Korea. The rain caused flooding along
the Tumen River, the border between North Korea and Russia. Several days after the flooding,
debris consisted with logs and household garbage were found along the East coast of Korea. The
debris, of course, had negative impact on the tourism and coastal eco system. In addition to the
debris landed on the East coast of Korea, there must be others drifting toward other areas or
floating in the ocean. Logs floating on coastal water could be hazardous to marine traffic, and
tracing the fate of the debris from the river is an important task. A Lagrangian particle model
utilizing ocean circulation model output is commonly used to trace marine litter. The debris due to
the typhoon is episodic and more focused approached is required. In addition, to cope with
potential danger posed by large flood debris near-real time tracking is indispensable. For real time
monitoring satellites are very useful. Debris is too small to be identified using a satellite. Flooded
water, however, could contain a large amount of sediment and could have distinct ocean color.
The trajectories of the debris from Lagrangian particle tracking modelling and the patterns of
anomalous ocean color are comparable. Typhoons hit Southeast Asia every summer causi
