ABSTRACT
Wando is a semi-closed water area whose hydraulic characteristic is different from the main stream. It served as spawning place and nursery ground of fish juveniles. In this study, field observations were carried out to understand physical conditions of Wando. Study site was at the right bank of the Kako River mouth. As a result, the difference of the amount of deposit and its vertical distribution between Wand and the main stream were clarified. Moreover, the decrement effect of waves by vegetation was also confirmed.
