| The seasonal variation of phosphorus loading into the Lake Dalbang was surveyed in the three streams (Dalbang, Seohak, and Shinhung stream), at $1{sim}2$ week intervals from April 1994 to March 1995. Also, the variation of phosphorus concentration during storm runoff was surveyed at the shorter intervals of $5{sim}8$ hours from October 10 to 22. The average of total phosphorus (TP) concentration in three inflowing water was 7.7 (Dalbang stream), 19.4 (Seohak stream), 40.0 (Shinhung stream) $mgP/m^3$. In addition, during the storm periods (October, 12, 1994) the average TP concentration was 98 (Dalbang stream), 190 (Seohak stream), 1,330 (Shinhung stream) $mgP/m^3$. Shinhung watershed was major pollution sources, since that area has about 70% of total phosphorus generation. Because the TP concentration and the flow rate of the three inflowing waters were high during the flood period, most of annual phosphorus loading was concentrated in several episodic storm runoff. TP loading from the watersheds was calculated to be 236.9 kgP/yr. TP loading during the rainy season (October and November) accounted for about 71% of TP loading of Lake Dalbang. TP loading from the Dalbang, Seohak and Shinhung watersheds were calculated to be 21.0, 64.1, and 151.9 kgP/yr, respectively. The delivery ratio of TP was 10.7. |
