  • The Barato River in northern Sapporo was formed from a cutoff meander of the Ishikari River. Since the river is in an urban area, it receives urban wastewater. As a largely enclosed water body withlittle exchange of water but with inflow load from the surrounding area, the Barato has undergone eutrophication, as evidenced by water bloom. We conducted a comprehensive study on the hydrological and material cycles of the Barato River basin. We clarified some causes of the water quality problem of the Barato River. One cause is rainfall runoff from the sewer system. Another is interaction between water and bottom deposits. The Barato River adjoins a backwater section of the Ishikari River, where flow alternates with backflow. Such a hydrological mechanism is considered to significantly affect the water and heat balances of the Barato River. In an effort to solve the eutrophication problem, we are conducting observations and simulations to identify additional causes, toward suggesting an effective water quality improvement method.
