EVALUATION OF THE IMPACTS OF CLIMATE CHANGE ON PHYTOPLANKTON CONCENTRATION DEPENDING ON THE SIZE OF DAM RESERVOIRS AND THE EFFECTIVENESS OF THE ADAPTATION MEASURE USING THE DESTRATIFICATION SYSTEM

Abstract

 Recently, the impact of climate change has been the serious effects on water environments. On dam reservoirs, it is concerned to advance eutrophication due to the increase of water temperature and nutrient loadings. Therefore, this study evaluated the impacts of climate change on phytoplankton concentration and the effectiveness of the destratification system as the adaptation measures depending on the size of imaginary dam reservoirs. As a result, the surface Chl-a concentration in May and June was tend to increase in the future climate change scenarios and the trend was stronger for scenarios with larger temperature increases and recognized in all the sizes of imaginary dam reservoirs. Furthermore, the estimation of water quality using the destratification system in the future climate change scenario indicated that it is possible to reduce the increased surface Chl-a concentration due to the impacts of climate change. These results showed the effectiveness of adaptation measures using the destratification system for eutrophication.
