This project concerns a numerical model that describes the atmospherical flows above a terrain with different types of vegetation. This numerical model was written in Fortran by dr. ir. R. Luppes in 1993. The aim of the project was to repair errors in the code with the help of mesh-refinement, which is possible because of the significant increase of memory of computers. This means we can do more computations in a shorter amount of time than back in 1993. The project will first consider the original model and its main problem, which is that the solutions of the model change if the top boundary layer changes in height. Then adjustments will be made to try to solve this problem. The main conclusion that grid refinement does not completely solve the main problem. The initial profiles resulting from different heights of the boundary layer do overlap, but the horizontal profiles still show deviation.
