Learning outcomes

After successful completion of the course, students are able to describe the basics of hydraulic engineering experiments at an academic level, to define the necessary model laws and model limits and to apply them to physical experiments in a meaningful way.

The basics of hydraulic engineering testing include the following topics:

- History, purpose and tasks of hydraulic engineering experiments

- Types, basic equipment and functioning of hydraulic laboratories

- Classification and model types of hydraulic models

- model laws - Basics of dimensional analysis

- mechanical, electrical and electronic measuring devices

- In-depth knowledge of building-, river engineering- and pipeline models

With this knowledge, the students can plan and carry out simple hydraulic model tests themselves, commission hydraulic model tests with correct content and critically analyze the results of model tests that have been carried out.

Subject of course

History of models in hydraulic engineering, similarity, scaling laws, get to know the dimensional analysis, river models with fixed or movable bed, models of hydraulic structures to find out discharge, energy dissipation, erosion, fluid forces and flow induced vi-brations, models of pipelines


Teaching methods

Lecture part:

Plenary lecture, guided tour through hydraulic engineering laboratory, self-study, discussion of projects

Exercise part:

Practical exercise in the hydraulic engineering laboratory in small groups with reference to practical issues

Mode of examination


Additional information

Exam mode when switching to online format:

The online exam is carried out entirely with ZOOM. It is a "written online exam on paper" according to the TU Wien guidelines.

Online exam procedure:

Webcam position: During the exam, the students have to align their webcam so that they and the desk can be seen (distance to the student approx. 1 - 1.5 m). If the webcam is integrated in the work device, the device must still be able to be operated by the student and the page with the test / information must be legible (e.g. adjust the font size). The camera (and the desk) should be positioned so that most of the room and the door can be seen. Make and check these settings offline in advance. If you don't have a webcam (separately or in your notebook / tablet) you can also use your smartphone (e.g. apps like DroidCam). The webcam must remain switched on during the entire test.

You should join the ZOOM web meeting (link in TISS) no later than 10 minutes before the start of the exam in order to have enough time for the setup. When entering the ZOOM web meeting, you have to authenticate yourself with your first and last name.

At the beginning of the test, the identity is checked using a video identification process (move head and student ID in front of the camera). Then a rotation of the camera through the room is required to ensure that there are no unauthorized aids or people in the room. The test is then started.

All participants are muted during the exam. Questions can be put to the examiner using the chat function.

During the entire test, the sound/loudspeaker must be activated in order to be able to hear and follow the auditor’s announcements. If fraud is suspected, the inspector's instructions must be followed (swiveling the camera again or releasing the current screen). If the exam participant does not follow the instructions or if a suspicion of fraud is confirmed, the exam will be canceled and this will be counted towards the permitted number of exam attempts.

In the event of technical interruptions, the examiner decides (depending on the duration and scope of the technical problems) whether the examination should be aborted or continued.

Do not write on the first sheet in the upper right corner (size of the student ID).

In order to submit the written examination, the described sheets (in full) must be scanned or photographed within 5 minutes after the examination and sent to the lecturer/examiner by email. The student ID is placed on the first sheet in the space reserved for it (top right corner) so that the student ID can also be scanned. Individual images may not be uploaded, only a coherent PDF document (use apps/programs (Adobe Scan, Office Lens)), make sure to test and familiarize yourself with them before the exam! The ZOOM web meeting connection must remain active during the scanning or photographing and uploading process, i.e. the scanning device must already be within range (if a smartphone is used as a webcam, this device CANNOT be used for scanning or photographing!).

The ZOOM web meeting connection is then terminated by the examiner after checking the submission. If students want to leave the exam before the end of the exam, this must be communicated via the chat; the connection is only terminated by the examiner. Should a student independently terminate the ZOOM web meeting connection during the exam, this will be considered an exam termination.

Assessment scheme for the online exam:

The assessment of the written online exam is carried out in the same way as the assessment of a written face-to-face examination.

 Required technical equipment for participation in the course and examination:


• PC / notebook / tablet with a camera, microphone and speakers (or headset)

• stable internet access


• PC / notebook / tablet with a camera, microphone and speakers (or headset)

• stable internet access

• an examination room in which the examinee is alone

• no disruptions during the exam

• 5 sheets of unlined white paper and writing materials (a transparent glass of water and a transparent beverage bottle without a label are allowed)

• a possibility to completely digitize/scan written sheets for submission (via scanner or smartphone scanner app)
