Course abstract

The aim of the study course is to provide students with opportunities to improve their knowledge of water cycle by taking into consideration the impacts and interactions of natural and anthropogenic factors. A set of knowledge and skills on methods and tools for measuring, calculating, forecasting and modeling hydrological parameters, as well as the applications of geographic information systems in analysis and visualization of hydrological processes are acquired during the study course.

Learning outcomes and their assessment

Upon the completion of this course students will have:
1. Knowledge and understanding in hydrology in terms of fundamental concepts, up-to-date research directions, and formation processes of natural waters - Test 1;
2. Ability to obtain, process, analyze and interpret results of hydrological measurements, as well as to apply theoretical and practical knowledge in evaluation and modeling of hydrological processes. Skills to use geographic information system software in determination, analysis and visualization of characteristics and hydrological regimes of water bodies - Test 2;
3. Competences to visualize results of hydrological processes modeling on a thematic map – Formal test.

Course Content(Calendar)

1. Introduction to hydrology, explanation of terminology, water cycle in nature (3 h).
2. Hydrology of rivers, lakes and bogs, the factors affecting hydrological processes (3 h).
3. Formation and characteristics of runoff in rivers (3 h).
4. Preparation and analysis of level-discharge relationships and hydrographs for hydrological observation stations (3 h).
5. Basic principles and applications in modeling of hydrological processes (3 h). Test 1 - the acquired theoretical knowledge.
6. Determination of catchment characteristics for a given river - acquisition, processing and analysis of geospatial information on the hydrological network and catchment area (3 h).
7. Determination of catchment characteristics for a given river - acquisition, processing and analysis of geospatial information on the digital elevation model (3 h).
8. Determination of catchment characteristics for a given river - acquisition, processing and analysis of geospatial information on the land use (3 h).
9. Determination of catchment characteristics for a given river - acquisition, processing and analysis of geospatial information on the soil properties (3 h).
10. Preparation of cross-sections for a given river (3 h).
11. Application of hydrology tools using a geographic information systems software (3 h). Test 2 - the acquired practical skills in the preparation of geospatial information.
12. The METQ model for hydrological processes modeling – structure, input data and setup (3 h).
13. Calibration and validation of the METQ model for hydrological processes modeling (3 h).
14. Analysis and interpretation of the results of hydrological processes modeling (3 h).
15. Application of the results of hydrological processes modeling in flood risk assessment (3 h).
16. Representation of the results of hydrological processes modeling on a thematic map (3 h). Formal test – the maps of flood risks with different exceedance probabilities should be prepared.

Requirements for awarding credit points

Formal test with a grade.
Two tests and one formal test must be passed according to the tasks and evaluation procedures specified for each work.

Description of the organization and tasks of students’ independent work

Student must independently prepare for two tests and one formal test using the information presented in all lectures and practical works and recommended literature.

Criteria for Evaluating Learning Outcomes

The final evaluation (100 points) upon completion of this study course will consists of the class attendance (10 points), Test 1 (20 points), Test 2 (20 points) and formal test (50 points).
The grades will be assigned based on the cumulative number of points obtained during the semester using the following scale:
4 - 41 ... 45 points;
5 - 46 ... 55 points;
6 - 56 ... 65 points;
7 - 66 ... 75 points;
8 - 76 ... 85 points;
9 - 86 ... 95 points;
10 - 96 ... 100 points.
