Hydrodynamic modelling of Prošćansko Lake
Within the project "Hydrodynamic Modeling of the Plitvice Lakes System", a hydrodynamic model of Prošćansko Lake was developed in order to facilitate management of water resources that are part of the protected area. The hydrodynamic model describes the physical processes that occur in the lake and at the water-air boundary. Shallow lakes respond quickly to atmospheric changes and forcing, so it is necessary to use an appropriate model that describes the processes of heat exchange at the water-air boundary, the processes of vertical mixing and turbulent energy transport between layers of the lake. Therefore, the 3D hydrodynamic model SCHISM (Semi-implicit Cross- scale Hydroscience Integrated System Model, Zhang et al.) was chosen. The model simulated the influence of atmospheric conditions above the lake of complex bathymetry and their coupling with the physical processes in the lake to gain insight into the thermal structure, currents, and changes in elevation of the lake. By adjusting various input variables (meteorological/hydrological data), model parameters (bottom friction coefficient, diffusion coefficients, albedo, windfactor, watertype), structuring the networks of different configurations, correctly selecting the numerically algorithms and the turbulent closure scheme, a good correlation between the model output variables (change in lake elevation and 3D temperature field) and measured values was reached.
