O článku:
Investigations indicate that correct estimation of seasonal thermal stratification in a dam reservoir is very important
for the dam reservoir water quality modeling and water management problems. The main aim of this study is to
develop a hydrodynamics model of an actual dam reservoir in three dimensions for simulating a real dam reservoir flows
for different seasons. The model is developed using nonlinear and unsteady continuity, momentum, energy and k-ε turbulence
model equations. In order to include the Coriolis force effect on the flow in a dam reservoir, Coriolis force parameter
is also added the model equations. Those equations are constructed using actual dimensions, shape, boundary
and initial conditions of the dam and reservoir. Temperature profiles and flow visualizations are used to evaluate flow
conditions in the reservoir. Reservoir flow’s process and parameters are determined all over the reservoir. The mathematical
model developed is capable of simulating the flow and thermal characteristics of the reservoir system for seasonal
heat exchanges. Model simulations results obtained are compared with field measurements obtained from gauging stations
for flows in different seasons. The results show a good agreement with the field measurements.
