Abstract
A handy method was developed to assess reservoir water quality before the completion of dam reservoirs using information such as river water quality which is available even before the completion of reservoirs. Regression equation for mean surface Chlorophyll-a concentration in summer was obtained by using water quality data which have been measured in existing reservoirs and flowing in rivers. Since this method provides quantitative water quality prediction, it can complement the water quality assessment made by numerical simulations. Also have analyzed were distributions of several water quality indices when common phytoplankton species are abundant. This analysis showed the preference of phytoplankton species and it can be used to predict dominant phytoplankton species in reservoirs qualitatively when combined with outcomes by numerical simulations.
