| Popis: | The goal of this study is the definition of the boundary conditions of a groundwater flow model by using rainfall data and trends of hydraulic heads in wells, to further calibrate it. The equations of the boundary conditions are comprised of a harmonic equation which derives from semiyearly rainfall data and a linear equation expressing the trends. The trends of the boundary conditions were approached as a function of the trend of the nearest well or as a function of the mean average of all trends. The criterion of improvement is the reduction of the error Bias, RMSE and MAE. In conclusion, the nearest well approach is proved to be superior by improving Bias by 22,83, RMSE by 14,88%, MEA 16,08%. This work was developed under the scope of the InTheMED project. InTheMED is part of the PRIMA programme supported by the European Union's Horizon 2020 research and innovation program under grant agreement No 1923. |
