2. Objectives and learning outcomes
2.1 Objectives
The aim of the course is to provide the students with theoretical and practical knowledge required for the hydromorphological assessment of rivers. Accordingly, the following will be covered during the semester: i) the theoretical description of flows, and their practical applicability, ii) flow measurement methods, iii) the role of turbulence, its theoretical description and measurement methods, iv) theoretical and empirical description, and measurement methods of sediment transport, v) the analysis of bed material, vi) large-scale morphological assessment of rivers, vii) geophysical bed surveys and viii) catchment-scale sediment transport processes. In addition to the lectures, students also take part in a field course where they apply the theoretical knowledge acquired during the semester.

14 Field course: introduction and preparation
Field course: 3 days in the exam period. The students are working in groups of 4-5 students in the BME measurement camp in Göd. The measurements are carried out in the section of the Danube River near Göd. The field course has three main parts: field data collection, laboratory analysis and data processing:
  1. Field data collection:
    • riverbed topography survey
    • water surface slope measurement
    • acoustic flow measurements
    • suspended sediment sampling
  2. Laboratory analysis:
    • determination of suspended sediment concentration and particle size distribution by us-ing traditional direct (filtration) and indirect methods (laser diffraction and infrared scattering)
  3. Data processing:
    • preparation of riverbed topography map
    • evaluation of flow data, identification of special flow structures
    • sediment load calculations
    At the end of the field course, the groups will submit a report presenting the hydromorphological characteristics of the studied section of the Danube River, based on their measurements and knowledge.

The above programme is tentative and subject to changes due to calendar variations and other reasons specific to the actual semester. Consult the effective detailed course schedule of the course on the subject website.

II. Subject requirements

Assessment and evaluation of the learning outcomes
3.1 General rules
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via: attendance to lectures, a midterm test, attendance to the field course and preparation of a field study report, and a written exam.
3.2 Assessment methods
Evaluation formAbbreviationAssessed learning outcomes
midterm testMTA.1-A.4
field course (continuous performance evaluation)FCB.1-B.6; C.1-C.5; D.1-D.2
written examEA.5-A.7

The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.
3.3 Evaluation system
3.4 Requirements and validity of signature
To obtain the signature, it is required that the student participates in at least 70% of the lectures, 100% of the field course, and completes the midterm test and the field course at least at a Sufficient level.
3.5 Grading system
Exam score less than 40% of the total results in an Insufficient mark.
In case of fulfilling the attendance requirements, and passing the midterm test and the written exam, the final grade is calculated as a weighted (according to 3.3.), rounded average of the score of the midterm test, field course and written exam.
3.6 Retake and repeat
The midterm test can be retaken or repeated once in the week of repeats, free of charge. In case of correction, the favourable result will be taken into account. If the student is not able to obtain a grade other than Insufficient with the replacement, he/she may make a second attempt after the payment of the fee specified in the Regulations.
However, the field course – due to its nature – cannot be retaken, repeated or otherwise replaced.
