Development of Predictive Method for Water Quality in a Bay by a Primary Ecological Model

Abstract

The objective of this research is to develop a method whereby the future of water quality leading to eutrophycation, origo-oxygen phenomena, etc. in the closed sea areas can be forecast and evaluated at a certain level. For this purpose, the environmental characteristics of the sea areas are researched from physical, chemical and biological aspects, and the condition of these characteristics is synthetically reproduced by means of the water quality model.
In this prediction and analysis of water quality, an attempt was made to predict the quality of water in Tokyo Bay on the basis of the flow field determined using the newly developed box model.
Comparison was made between calculations reproducing the present condition of the water quality in summer and measured values. As a result, we consider it basically possible to reproduce many items and to examine the effect of water quality in a diversified manner.
