Hydrology

The course aims at familiarizing students with basic concepts of Hydrology, and the use of Geographic Information Systems and Remote Sensing data for implementing integrated hydrological studies. By the end of this course the students will be able to:

1. Understand the concepts of hydrological cycle and hydrological balance.
2. Understand the concepts of spatial analysis and to use tools of spatial interpolation..
3. Study, process and analyse statistically hydrological data from stations or databases.
4. Process digital elevation models for extracting hydrological elements in GIS environment.
5. Process thermal and multispectral Remote Sensing data for calculating evapotranspiration

By the end of this course the student will, furthermore, have developed the following skills:

1. Analogue and digital calculation of basic parametres of the hydrological balance in GIS environment.
2. Analogue and digital calculation of morphometric parametres of drainage basins and drainage networks in GIS environment.
3. Implementation of integrated hydrological studies.
4. Buiding drainage and flood models in GIS environment.

In total, students after successful completion of the semester will be able to demonstrate their knowledge in hydrology,  to solve hydrological problems with the use of Geographic Information Systems and Remote Sensing data, to write independently integrated hydrological studies, and to produce thematic maps for information transfer to the public and the related services.
