On the Spatial Distribution of Aquatic Plant in Gravel River
Author : Ryota Tsubaki and Yoshihisa Kawahara
The growth of submerged aquatic plants is one of the important components of the river ecosystem. A vast amount of invasive aquatic plant communities has taken root in the Gono River system in Japan, and this changed the river ecosystem substantially. In this paper, a seasonal change in the spatial distribution of the aquatic plant in a gravel bed river has been surveyed. The growth, shrink due to aging and washing-out due to flood are analyzed using the images recorded by the time-lapse cameras. The characteristics of the flow through aquatic plant communities with different arrangement are evaluated using a shallow water flow model.
