Abstract
en
The Barato River is largely an enclosed water area, the flow tends to become stagnant and the river is subject to the inflow of pollution loads from its surrounding areas. As a result, the growth of green algae and other eutrophication phenomena have emerged in recent years. To prevent the Barato River from becoming eutrophicated, it is necessary to understand the space structure and formation factors of the water quality. In this study, the focus is placed on the topographical classification of upper, middle and lower lake basins in calculating the water and load balances for each of these basins. The water and load balances are clarified in consideration of the complex outflow routes of the river water via urban sewerage. As a result, it was learned that incoming loads at times of rain and the loads from bottom sludge may be the primary supply source of suspended solids in the river. Based on the calculation results, this paper aims to comprehend characteristics related to the formation of water quality of each lake basin, in order to use these characteristics as the basic data for the purification of water quality and the preservation of the water environment.
