Abstract—Water quality of the second Songhua River is
affected by both tributary pollution loads and upper boundary.
A set of hydrodynamics and water quality coupling model of the
second Songhua River was developed. Based on the model, the
pollution contribution ratios of tributaries pollution loads and
boundaries were ascertained. The impacts of the change of
water qualities of upper boundary and tributary were analyzed,
and the farthermost water quality improvement of second
Songhua River when upper boundary being better and
tributary meeting Class III of National Surface Water Quality
Standard was predicted. The results indicated: 1)if the
tributary (Yinma river )meets Class III of National Surface
Water Quality Standard, the water quality of WUJIA water
quality monitoring station in Songhua river improving will be
bigger from Jun through Aug, Ammonia and Nitrogen Index
was significantly improved, but to upper boundary, this kind of
impact is bigger. 2) Both reducing the tributaries pollution
loads and improving upper boundaries are necessary for
improving water quality in the second Songhua River.
Index Terms—Mathematical model, the second Songhua
River, tributary, water qualities.
