2. Objectives and learning outcomes
2.1 Objectives
The objective of the course is to give an introduction to hydrology within civil engineering, to its sub-disciplines and related fields. The student will learn about the global hydrological cycle, its elements and the estimation of the related fluxes; will master basic concepts in hydrometeorology, such as precipitation, evaporation, infiltration and runoff. He/she will be acquainted with the physical properties of streamflow and descriptors of lakes and groundwater. Will learn about the basic concepts of hydrometry and hydrography and eventually will be able to complete hydrological calculations related to civil engineering design.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. Knows the general jargon in hydrology and its relation to civil engineering applications.
  2. Able to list components of the water balance.
  3. Knows calculations pertaining to the water balance of small catchments.
  4. Able to list groupings of streams and lakes, their most important concepts.
  5. Became familiar with the methods of hydrometry and hydrography.
  6. Knows basic concepts of hydrogeology and their measurement methods.
B. Skills
  1. Can put into practice the mastered hydrological procedures.
  2. Able to conduct simple hydrological calculations.
  3. Employs empirical relationships in practice.
  4. Can Design precipitation measurements and analyse the measured data.
  5. Estimates design flood discharge levels for small catchments and understands simpler rainfall-runoff methods.
  6. Interprets hydrographic data, manipulates such databases.
  7. Able to express his/her thoughts in an organized fashion.
C. Attitudes
  1. Open to the use of information technology.
  2. Strives to achieve accurate problem solution.
D. Autonomy and Responsibility
  1. Independent in solving hydrological problems with available information sources.
  2. Employs a system-theory approach.
2.3 Methods
Lectures, exercise classes, written and oral communications, application of IT tools and techniques, assignments solved individually.

3.3 Evaluation system
3.4 Requirements and validity of signature
No signature can be obtained.
3.5 Grading system
At least 70% of the attendance of lectures and seminars/exercise classes are expected.
A midterm tests not exceeding 50% of the maximum score is failed.
In case of fulfilling the attendance requirements and passed midterm tests and homework assignments, the final grade is the average value of the grade of the midterm tests and the homework assignments weighted according to the clause 3.3.
3.6 Retake and repeat
  1. Homework – after the payment of the fee as described in the Regulations – can be submitted with delay until the deadline described in the Detailed course schedule.
  2. The submitted and accepted homework can be corrected without any fee until the deadline described in the point 1.
  3. The two midterm tests can be retaken free of charge. The date of the retake is described in the detailed course schedule. In case of correction the previous result will be replaced with the new result.
