Two-dimensional Modelling of Accidental Flood Wave Propagation 87Implementation of the initial and boundary conditions. Model calibration.The initial conditions refer to the overall calculation time and to the time step,parameters considered to be the global parameters of the model. In the case ofPoiana Uzului pilot project, the overall calculation time was Tt = 40000 s, and thetime step t = 300 s. The boundary conditions are implemented at the inlet andoutlet of the model and they are necessary for solving the equations system duringthe calculation.For the two scenarios an „inflow hydrograph” was introduced at the inlet of themodel (fig. 15), and downstream, at the outlet of the model, an „energetic slope”was defined (fig. 16). Due to the non-existence of a similar incident in the historyof the area, the calibration of the model could not follow a real event. Thecalibration might have helped to obtain an accurate adjustment of the roughnesscoefficients. Due to the lack of such data, the calibration of the model was notpossible. As mentioned before, the value of the roughness in the minor and majorriver bed was approximated on the basis of informations gathered during sitevisits and existing maps.Fig. 15.
