Quality of Water in Yamada River and Measures for a Maintaining Water Quality Control

Basic studies on the management of water quality used for agriculture water (III)

Abstract

In building up a water quality management system for the Yamada River Basin, the following procedures are important.
1) urderstanding the water pollution characteristics of the basin
2) water quality modeling and parameter estimation
3) predicting the quality of water in the future maintaining
4) planning measures for water quality
In this paper, we discuss the trial estimation of predicting the future quality of the Yamada River, using the water quality model presented in the last paper.
Secondly, supposing some measures for cutting the pollution load which would be produced in the basin in the future, we estimated the improvement in water quality by putting certain measures into practice.
