According to the particular factors of hydrology, geography, and meteorology, building a proper water quality model should consider with the local characteristics and water identity.
This study analyzes the water quality simulation of Shih-Men reservoir, bases on the CE-QUAL-W2 developed by Waterway Experimental Station, U.S. Army Corps of Engineer. Assuming the volume of reservoir changing with time and taking into account of drift, settling, and disappearance of pollution, the relationship of water temperature and pollution distribution is discussed.
One can safely state that, CE-QUAL-W2 can get the trend of water simulation variation. Just only wet period comes, the concentration of water quality in the reservoir get higher. In conclusion, the change of water temperature of reservoir not only affects the change of fluid dynamic but also greatly worsens the water quality. There is only a slight relationship between the change of fluid dynamic and the quantity of water draws off in usual. Nevertheless, the descending temperature and disappearing stratification during the transient between summer and winter leading to severe overturn in reservoir generates sever change of reservoir fluid dynamic.||en_US|
