2. Objectives and learning outcomes
2.1 Objectives
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.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. Familiarity with the most frequently encountered time series concepts and models employed in hydrological research and ability to apply them for one’s own research.
  2. Knows how to generate stochastic time-series with the Monte-Carlo approach.
  3. Aware of the conditions necessary for applying the Kalman filter for optimal model parameter estimation.
  4. Familiar with linear hydrological models and knows how to modify them for one’s own purpose.
B. Skills
  1. Advanced problem solving capacity in hydrological modelling and forecasting using linear and time series models.
  2. Thorough knowledge of linear models of hydrology, their modifications and problem-specific applications.
  3. Thorough understanding of time series models often employed in hydrology and water resources research, their correct applications and strengthened skill to further develop such models.
  4. Aptitude for writing MATLAB code performing „brute-force” calibration and its application for solving problems in hydrology and civil engineering.
  5. Capacity of solving complex modelling problems by MATLAB.
C. Attitudes
  1. Cooperates with the instructor during the learning process.
  2. Continuously and actively seeks ways of gaining knew knowledge even beyond the required curriculum and employs the internet for finding intuitive answers to research problems.
  3. Open to learn new software skills.
  4. Attempts to perform precise problem solutions.
D. Autonomy and Responsibility
  1. Resolution to solving homework on one’s own within feasible limits.
2.3 Methods
Lectures on theory. Practical guidance about the steps needed for solving computational/modelling problems and the software required. Consultation of the homework individually or in groups using one’s own laptop on top of written (e-mail) and personal oral communication during consultation hours.
