| 1996년 7월에 유입된 소양호의 인부하량은 418.2tP/month로서 6월의 6.0tP/month에 비해 상당히 컸으며 6월에서 10월까지 유입된 총인부하량의 약 7.8%만이 방류구를 통해 방류되었다. 소양강의 탁도는 갈수기에 $1{sim}3NTU$, 홍수기에 $2{sim}78NTU$로 높았다. 홍수시 유입된 탁수는 같은 밀도의 수층을 따라 중층으로 댐까지 이동하였으며 탁수층에서 총인농도는 $20{sim}230;mgP/m^3$의 범위를 보였다. 홍수기 이후의 9월에도 댐앞 방류구 위치에 탁도와 인농도가 각각 $3{sim}6;NTU,;14{sim}33;mg/m^3$인 물이 남아 있었으며 이것은 가을 수직 혼합시에 표층으로 공급되는 것으로 나타났다. |

| In Korea most of nutrient loading into lakes is concentrated in stormy seasons. Phosphorus loading and transport of turbid storm runoff water was investigated in a reservoir, Lake Soyang, Korea. Concentration of phosphorus was measured at ten meter intervals on the monthly base in dry seasons and biweekly in stormy seasons. The loading from drainage basin was detemined by measuring total phosphorus (TP) concentration in the main inflowing stream, the Soyang River. Because total phosphorus concentration and flow rate of the Soyang River was high in flood period, most of annual phosphorus loading was concentrated in several sporadic storm runoff. In July of 1996 phosphorus input was 418 tP/month. It was much higher than that in June, 6.0 tP/month. 10% of annual total phosphours input was discharged through outlet during the period from June to October. Turbidity was much higher $(2{sim}78;NTU)$ in stormy seasons than in dry seasons $(1{sim}3;NTU)$. Cold storm runoff laden with high turbidity and phosphorus flowed into metalimnion along the layer of same density. Total phosphours concentration of intermediate turbid water ranged from 20 to $230;{mu}g^p/m^3$. After stormy seasons high nutrient concentration was con-sistently observed at intermediate layer until autumn turnover. In autumn descending mixing depth caused increase of phosphorus concentration in the epilimnion. |
