The one-dimensional numerical simulation model of reservoir hydrodynamics, DYRESM, is used to examine the effects of Retention Time (RT) on reservoir stratification. The model is verified using data from 3 years of high flow (short retention time, RT), on two reservoirs in the Czech Republic. The ve
