The course "Hydraulics II" is a basic core lesson with a focus on practical demonstration and application of the theoretical concepts taught in the Hydraulics I course of the previous semester.
The course introduces practical concepts such as the measurement of basic hydrological variables in a wide range of applications (from the measurement of atmospheric variables such as precipitation, surface hydrological variables such as river flow and underground hydrological such as aquifer level).
Experimental measurements in the lab serve to confirm fundamental concepts and theories of surface and underground hydrology.

Further objectives of the course are to understand the importance of the systematic recording of hydrological parameters and their importance in the management of water resources.

Upon successful completion of the course, the student has acquired the following skills:

• Ability to process experimental and numerical data.
• Ability to solve the equations for flow in open flow channels.
• Ability to determine hydraulic jump parameters.
• Ability to calibrate H-Q equations over rectangular, vee notch and broad crested weirs.4
• Capacity to identify flow type in open channels
• Ability to identify and apply appropriate equipment to measure river flow.
• Ability to assess the suitability of the control cross-sections.
• Ability to estimate flood peak discharge

• Practical understanding of concepts / theories
• Advance free, creative and causative thinking
• Work in groups
