Course abstract

The aim is to ensure, during training practice, that the student strengthens and supplements knowledge of river hydrological issues, familiarises himself with instruments for measuring flowrates of watercourses. Students familiarize themselves with the issues of lake research and management. Students shall carry out a survey of the water body in nature and an identification of indicative species allowing for the determination of the trophic status of the water body. Perform a morphological survey of the water body and a description of the problems. Practical training provides the competence of students to address issues relating to the protection of water bodies and the improvement of their ecological status.

Learning outcomes and their assessment

After successful completion of this course, student:
Shall be familiar with the basic questions on the ecological processes of the water body, the anthropogenic factors and techniques affecting it for improving the quality of the marine environment. Strengthened and enhanced knowledge on theoretical and practical issues of hydrometry.
• be able to apply theoretical knowledge by determining the atrophic level of the water body, by identifying anthropogenic factors affecting the water body.

• The ability to apply the acquired skills and the necessary information to perform hydrological calculations. Competence to develop a water body management plan. (practice report)
