Publikováno v: Journal of Japan Society of Civil Engineers, Ser. B2 (Coastal Engineering). 66:446-450

This study was aimed at investigating temporal and spatial variations of the bottom sediment characteristics at Tama River mouth in Tokyo Bay. The bottom sediment samples were taken every 3 months from 28 points, including an offshore site(

Flows of the Bottom Layer in Tokyo Bay and Its Influence on the Bottom Water in Dredged Trench

Autor: Kazunobu Morohoshi, Kojiro Suzuki, Ryuichi Ariji, Shoichi Matsuzaka, Nobuaki Suzuki, Yoji Tanaka

Publikováno v: PROCEEDINGS OF COASTAL ENGINEERING, JSCE. 55:1031-1035

At the head of Tokyo bay, blue tides often occur from summer to autumn by the bottom layer upwelling. It is a factorof blue tides that the anoxic water in the bottom of dredged trench produces sulfide in high concentration. The purposeof this paper i

Publikováno v: PROCEEDINGS OF COASTAL ENGINEERING, JSCE. 55:1081-1085

Temporal and spatial variations of hypoxic water mass in Tokyo Bay were investigated based on intensive field surveys coupled with numerical simulation in Summer 2007. Measurements results showed that the hypoxic water mass existed in the bottom laye
