  • The Barato River is the largest oxbow river channel formed by cutoff works on the Ishikari River. Its water areas has polluted as a result of flow stagnancy and inflow of pollutant loads from urbanized areas. While organic pollution has been considerably reduced by pervasion of the sewage system, it is still in an eutrophication condition and further improvement of the Bataro’s water environment is needed. In planning effective water quality improvement measures in a water body as long as the Barato, which runs for 20 km, the eutrophication condition needs to be understood in terms of spatial characteristics. To clarify the causes of eutrophication in the Barato River, an attempt was made to investigate the temporal and spatial changes in water quality using novel technology (a towed meter and remote sensing). The results suggest that the degree of eutrophication depends on substances and the stagnancy characteristics of water body.
