Description

The Mogami River, which rises from Mt. Azuma, receives at Terazu of Tendo City a strong acid water river the Sukawa rising from Zao Spa. (the Mogami pH 7.1, the Sukawa pH 3.8). As the consequence, the ample water of the Mogami River is polluted into an acid water. I examind the mixing mechanism of different waters after the conflux of both the rivers. The results obtained are shown in the tables and diagrams.<BR>1) The waters of both the rivers do not mix easily before they come to the Murayama Bridge 3.4km down from the junction of two rivers.<BR>2) The distribution of pH (fig. 5) shows that it is closely related to the topography of the course of the river as shown in Fig. 1.<BR>3) From the results of analysis, it is able to find the pumping places of water suitable for industrial and irrigation purposes.
