This research was conducted with the aim of efficiently managing large scale rivers such like Dalcheon through predicting water quality change with analyzing the characteristics of the flowing in nutrients and pollutants.
The main result outcome will be used as basic data for effectively operating reservoirs through controlling water quality and quantity. The relationship between quantity of flow and water quality was analyzed and pollution loading into the basin was estimated.
The correlation between quantity of discharge and pollution concentration and between quantity of discharge and pollution loading were analyzed by statistical method, respectively. we analyzed the correlation between quantity of discharge per unit area and pollution loading per unit area in each basin.
At dry season dissolved oxygen in occasion of Chungjucheon 5.9 ~ in the case of 9.5mg/l, urethra thousand 5.1 ~ appearing by 11.0mg/l generally good value appear .
Chungjucheon, whole concentrations do not change greatly both urethra thousand but can know special quality of rivers that pass urban district being expose that Chungjucheon that is piercing insect starting gaze is less sheep of dissolved oxygen averagely than urethra thousand.
At dry season T-N, T-P in occasion of Chungjucheon 0.403 ~ 10.50mg/l, 0.204 ~ in the case of 0.640mg/l, urethra thousand 1.02 ~ 3.00mg/l, 0.199 ~ value of 0.250mg/l appear .
The occasion of Chungjucheon if see correlation coefficient of discharge and pollution loading at rainy season BOD in the case of 0.816, urethra thousand, SS item appeared by thing which interrelationship is the lowest by 0.8607.
In the case of Chungjucheon, is judged by inflow of domestic sewage, and in the case of urethra thousand, is judged that suspended solids of urethra thousand upper stream construction sites forms interrelationship low reacting brittlely about flux.
Is judged that agree comparatively in presented expression because comparative high interrelation is seen appearing from two riverses of remainder quality of water items to sphere of 0.9039 ~ 0.9763 at rainy season.
A value that display base flow at dry season urethra thousand is displaying 1.0171 in the case of 0.3838, Chungjucheon from BOD item and base flow BOD concentration of Chungjucheon is displaying high value.
Because other quality of water items is higher than urethra cloth base flow price in general in Chungjucheon, show that quality of water of urban river is bad comparatively at dry season.
Can know that pollution loading by discharge increase reacts sensitively by 3.1775 in the case of 3.6913, urethra thousand in Chungjucheon in occasion of SS at dry season.
T-P, occasion of T-N was expose that pollution loading reacts sensitively according to discharge increase at dry season
