Abstract |
This study has been performed to investigate water quality and organic loading on Shingal reservoir and its tributries in order to collect basic data and to apply future hydrological and systemic water supply planning. Following results were obtaind, 1. The lower reaches of Shingal stream was more polluted than upper or middle reaches of a stream. Annual average BOD concentration of Site-4 which passed by Shingal Yub, was about 33.36㎎/1, and annual average COD concentration was 71.34㎎/1. The water quality of site-4 was worse than that of downstream(site-5), and proper measure is necessary to prevent water pollution. 2. For the vertical distribution of temperature in Shingal reservior, the stratification occurred in summer and winter, but not in spring and fall. 3. For the organic loading, domestic animals contributed most with 36% and residents contributed 34.1% of total BOD loading. 4. BOD loading estimation equation of Shingal reservoir was obtained from stepwise multiple regression analysis, and this equation was statistically significant(R²=0.7704, p$lt;0.001). |
