The study looked at how sediment moves along the Ishikawa coast in Japan, focusing on both local and regional factors. By analyzing data over 12 years, researchers found that sediment transport in the surf and offshore zones goes in opposite directions. Sediment from rivers and longshore transport contribute to sediment buildup in the surf zone, while outflow processes lead to a decrease in sediment in the offshore zone. The study also suggests a clockwise circulation pattern for sediment movement. This method can be used to study sediment transport in other coastal areas and help with future research on coastal sediment dynamics.
