2. Célkitűzések és tanulási eredmények
2.1 Célkitűzések
The course will focus on time series and linear models most frequently employed in hydrology. Solution of the practical problems with the help of MATLAB will enable one to apply, modify and build such models on one’s own for hydrological/civil engineering research.
