2. Objectives and learning outcomes
2.1 Objectives
The objective of the course is that the student get familiar with system theory, linear algebra and linear systems in general for solving simple hydrological problems and also advance his/her skill of MATLAB programming. Other objectives are that the student get acquainted with the hydrological forecasting approach having been used operatively in Hungary for over 30 years now, widen his/her knowledge on time series modelling, be able to solve such practical problems, get an insight into information systems used in hydrology, into flood forecasting, into data-driven models and optimization techniques employed in the water management practice in Hungary.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
- 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.
- Knows the function of the Hungarian hydro-informatics system.
- Knows the different service levels, modelling, and data requirements for flood alerting and forecasting.
- Can give examples for data-driven approaches and optimizations in water resources management.
B. Skills
- Advanced problem solving capacity in hydrological modelling and forecasting using linear and time series models.
- horough knowledge of linear models of hydrology, their modifications and problem-specific applications.
- 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.
- Aptitude for writing MATLAB code performing „brute-force” calibration and its application for solving problems in hydrology and civil engineering.
- Capacity of solving complex modelling problems by MATLAB.
C. Attitudes
- Cooperates with the instructor during the learning process.
- 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.
- Open to learn new software skills.
- Attempts to perform precise problem solutions.
D. Autonomy and Responsibility
- 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.

3.4 Requirements and validity of signature
Non-relevant.
3.5 Grading system
The table displays the final grade limits. The average grade of the homework assignments counts by 70% while the grade of the final test by 30%. The percentages are relative to the maximum score.
The final test must be completed by at least 40% of the maximum score.
| Grade | Score (P) |
| excellent (5) | 85%<=P |
| good (4) | 70<=P<85% |
| average (3) | 55<=P<70% |
